The ISL6324A dual PWM controller delivers high efficiency and tight regulation from two synchronous buck DC/DC converters. The ISL6324A supports hybrid power control of AMD processors which operate from either a 6-bit parallel VID interface (PVI) or a serial VID interface (SVI). The dual output ISL6324A features a multi-phase controller to support uniplane VDD core voltage and a single phase controller to power the Northbridge (VDDNB) in SVI mode. Only the multi-phase controller is active in PVI mode to support uniplane VDD only processors. A precision uniplane core voltage regulation system is provided by a 2-to-4-phase PWM voltage regulator (VR) controller. The integration of two power MOSFET drivers, adding flexibility in layout, reduce the number of external components in the multi- phase section. A single phase PWM controller with integrated driver provides a second precision voltage regulation system for the North Bridge portion of the processor. This monolithic, dual controller with integrated driver solution provides a cost and space saving power management solution. For applications which benefit from load line programming to reduce bulk output capacitors, the ISL6324A features output voltage droop. The multi-phase portion also includes advanced control loop features for optimal transient response to load application and removal

The ISL6324 is a monolithic dual PWM hybrid controller with I2C interface designed by Linear Technology for AMD SVI Split-Plane and PVI Uniplane processors. This device supports dual outputs, including a multiphase controller supporting uniplane VDD core voltage and a single phase controller supporting Northbridge (VDDNB) voltage. In SVI mode, ISL6324's multiphase controller is active, only supporting uniplane VDD processors. In PVI mode, ISL6324's multiphase controller is not active, only supporting uniplane VDD processors.

The ISL6323B is a monolithic dual PWM hybrid controller supporting AMD SVI split-plane and PVI uniplane processors, providing high efficiency and tight regulation

This is a Monolithic Dual PWM Hybrid Controller that supports AMD SVI Split-Plane and PVI Uniplane processors and provides high efficiency and tight regulation of synchronous buck DC/DC converters.

The ISL6323 is a hybrid SVI/PVI monolithic dual PWM hybrid controller that powers AMD SVI split-plane and PVI uniplane processors

The ISL6265A is a multi-output controller with integrated MOSFET drivers for AMD SVI capable mobile CPUs. It features a single-phase controller for the Northbridge portion of the CPU and two additional channels that can be configured for two-phase or individual single-phase outputs. The ISL6265A can be used for both uniplane and dual-plane processors. It utilizes Intersil's R3 Technology™ for faster transient response.

ISL6265 is a multi-output controller with integrated MOSFET drivers from Intersil for AMD SVI capable mobile CPUs. The ISL6265 features a single phase controller that powers the Northbridge (VDDNB) portion of the CPU. The remaining two controller channels can be configured for two-phase or individual single-phase outputs. For uniplane CPU applications, the ISL6265 is configured as a two-phase buck converter. This allows the controller to interleave channels to effectively double the output voltage ripple frequency and thereby reduce output voltage ripple amplitude with fewer components, lower component cost, reduced power dissipation, and smaller area. For dual-plane processors, the ISL6265 can be configured as independent single-phase controllers powering VDD0 and VDD1. The heart of the ISL6265 is Intersil’s patented R3 Technology™, the Robust Ripple Regulator modulator. Compared with the traditional buck regulator, the R3 Technology™ has a faster transient response. This is due to the R3 modulator commanding variable switching frequency during a load transient. The Serial VID Interface (SVI) provides the means for the CPU to communicate with the ISL6265 via the I²C bus and thus receive input voltage, output voltage, and temperature information.

The HIP4020 is a half amp full bridge power driver for small 3V, 5V and 12V DC motors. This device has 4-quadrant load control function, which can change the direction of current flow by controlling the voltage between OUTA and OUTB terminals.

ISL6801 is a high voltage bootstrap high side driver produced by Intersil. It has two independent output pins that can independently control the rise and fall times.

The ISL6700 is an 80V/1.25A peak, medium frequency, low cost, half-bridge driver IC. It is available in 8-lead SOIC and 12-lead QFN plastic packages. The low-side and high-side gate drivers are independently controlled and matched to 25ns. This gives the user maximum flexibility in dead-time selection and driver protocol. Undervoltage protection on both the low-side and high-side supplies force the outputs low. Non-latching, level-shift translation is used to control the upper drive circuit. Unlike some competitors, the high-side output returns to its correct state after a momentary undervoltage of the high-side supply.

The ISL2110 and ISL2111 are 100V high-frequency half-bridge N-Channel power MOSFET driver ICs. They are based on the popular HIP2100 and HIP2101 half-bridge drivers, but offer several performance improvements. The peak output pull-up/pull-down current has been increased to 3A/4A, which significantly reduces switching power losses and eliminates the need for external totem-pole buffers in many applications. Additionally, the low end of the VDD operational supply range has been extended to 8VDC. The ISL2110 has additional input hysteresis for superior operation in noisy environments, and the inputs of the ISL2111, like those of the ISL2110, can now safely swing to the VDD supply rail.

ISL2100A, ISL2101A 100V, 2A Peak, High Frequency Half-Bridge Drivers are Intersil's 100V high frequency half bridge N-channel power MOSFET driver ICs. They have input hysteresis, DFN package, 100V conductor spacing guidelines, Pb-Free Plus Anneal, pin voltage max to 114VDC, 1Ω pin diode, multi-MHz circuits fast propagation time, 1nF load typical rise/fall time 10ns, CMOS compatible input thresholds, 3.3V/TTL compatible input thresholds, independent inputs provide flexibility, no start-up problems, outputs unaffected by supply Gl etc.

isl83202 is a medium-frequency h-bridge fet driver from isl company. Its rated voltage is 55v and its driving current is 1a, which is used to drive high- and low-side n-channel mosfets in medium-voltage applications. It is optimized for pwm motor control and uninterruptible power supply systems, and isl83202 enables simple and flexible bridge-based design. With typical input-to-output propagation delays as low as 25ns and with a user-programmable dead-time range of 0.1µs to 4.5µs, the isl83202 is ideal for switching frequencies up to 200kHz. The dead-time of the isl83202 is programmable via a single resistor. The isl83202's four independent driver control inputs (ali, ahi, bli, and bhi) allow driving of every possible switch combination except those that would cause a shoot-through condition. A global disable input, dis, overrides input control and causes the isl83202 to refresh the bootstrap capacitor when pulled low. Integrated undervoltage protection and shoot-through protection ensure reliable system operation. The isl83202 is available in compact 16 Ld soic and 16 Ld PDIP packages and operates over the range of -55°c to +125°c.
