intersil ISL6324A date data
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
intersil ICL7660 date data
The ICL7660 and ICL7660A are monolithic CMOS power supply circuits that offer unique performance advantages over previously available devices. The ICL7660 performs supply voltage conversions from positive to negative for an input range of +1.5V to +10.0V, resulting in complementary output voltages of -1.5V to -10.0V. The ICL7660A does the same conversions with an input range of +1.5V to +12.0V, resulting in complementary output voltages of -1.5V to -12.0V. Only 2 noncritical external capacitors are needed for the charge pump and charge reservoir functions. The ICL7660 and ICL7660A can also be connected to function as voltage doublers and will generate output voltages up to +18.6V with a +10V input. Contained on the chip are a series DC supply regulator, RC oscillator, voltage level translator, and four output power MOS switches. A unique logic element senses the most negative voltage in the device and ensures that the output N-Channel switch source-substrate junctions are not forward biased. This assures latchup free operation. The oscillator, when unloaded, oscillates at a nominal frequency of 10kHz for an input supply voltage of 5.0V. This frequency can be lowered by the addition of an external capacitor to the “OSC” terminal, or the oscillator may be overdriven by an external clock. The “LV” terminal may be tied to GROUND to bypass the internal series regulator and improve low voltage (LV) operation.

The ICL7660S Super Voltage Converter is a monolithic CMOS voltage conversion IC that offers significant performance advantages over similar devices. It is a direct replacement for the industry standard ICL7660, with an extended operating supply voltage range up to 12V and lower supply current. The ICL7660S does not require an external diode. Additionally, a Frequency Boost pin allows for achieving lower output impedance using smaller capacitors. All improvements are detailed in the “Electrical Specifications” section on page 3. Critical parameters are guaranteed across commercial, industrial, and military temperature ranges. The ICL7660S performs positive to negative supply voltage conversion for an input range of 1.5V to 12V, resulting in complementary output voltages of -1.5V to -12V. Only 2 non-critical external capacitors are needed for the charge pump and charge reservoir functions. The ICL7660S can function as a voltage doubler, generating up to 22.8V with a 12V input.
