The EL5192 and EL5192A are current feedback amplifiers with a very high bandwidth of 600MHz. This makes these amplifiers ideal for today’s high speed video and monitor applications. With a supply current of just 6mA and the ability to run from a single supply voltage from 5V to 10V, the amplifiers are also ideal for hand held, portable or battery-powered equipment. The EL5192A also incorporates an enable and disable function to reduce the supply current to 100µA typical per amplifier. Allowing the CE pin to float or applying a low logic level will enable the amplifier. The EL5192 is offered in the 5-pin SOT-23 package and the EL5192A is available in the 6-pin SOT-23 as well as the industry-standard 8-pin SO packages. Both operate over the industrial temperature range of -40°C to +85°C.

ISL6227 Dual Mobile-Friendly PWM Controller with DDR Option

ISL1557 is a dual operational amplifier designed by Intersil for VDSL2 and ADSL line driving in DMT based solutions. This device features a high drive capability of 750mA while consuming only 6mA of supply current per amplifier and operating from a single 4.5V to 12V supply. The driver achieves a typical distortion of -80dBc, at 150kHz into a 25Ω load. The ISL1557 is available in the thermally-enhanced 16 Ld QFN package and is specified for operation over the full -40°C to +85°C temperature range. The ISL1557 has control pins C0 and C1 for controlling the bias and enable/disable of the outputs. These controls allow for lowering the power to fit the performance/power ratio for the application. The ISL1557 is ideal for ADSL2+, SDSL, HDSL2 and VDSL line driving applications, including both 14.5dBm and 21dBm applications.

The CA3262 and CA3262A are used to interface low-level logic to high current loads. Each Power Driver has four inverting switches consisting of a non-inverting logic input stage and an inverting low-side driver output stage. All inputs are 5V TTL/CMOS logic compatible and have a common Enable input. Each output device has independent current limiting (ILIM) and thermal limiting (TLIM) for protection from over-load conditions. Steering diodes connected from each output (in pairs) to the Clamp pins may be used in conjunction with external zener diodes to protect the IC against over-voltage transients that result from inductive load switching. To allow for maximum heat transfer from the chip, all ground pins on the DIP, PLCC and SOIC packages are directly connected.

IRF140 is a power MOSFET produced by Intersil. It has a rated current and voltage of 28A and 100V, respectively, and a conduction resistance of 0.077Ω.

ISL6609, ISL6609A Synchronous Rectified MOSFET Driver is a high frequency, MOSFET driver optimized to drive two N-Channel power MOSFETs in a synchronous-rectified buck converter topology. This driver combined with an Intersil ISL63xx or ISL65xx multiphase PWM controller forms a complete single-stage core-voltage regulator solution with high efficiency performance at high switching frequency for advanced microprocessors. The IC is biased by a single low voltage supply (5V), minimizing driver switching losses in high MOSFET gate capacitance and high switching frequency applications. Each driver is capable of driving a 3nF load with less than 10ns rise/fall time. Bootstrapping of the upper gate driver is implemented via an internal low forward drop diode, reducing implementation cost, complexity, and allowing the use of higher performance, cost effective N-Channel MOSFETs. Adaptive shoot-through protection is integrated to prevent both MOSFETs from conducting simultaneously. The ISL6609, ISL6609A features 4A typical sink current for the lower gate driver, enhancing the lower MOSFET gate hold-down capability during PHASE node rising edge, preventing power loss caused by the self turn-on of the lower MOSFET due to the high dV/dt of the switching node. The ISL6609, ISL6609A also features an input that recognizes a high-impedance state, working together with Intersil multiphase PWM controllers to prevent negative transients on the controlled output.

ISL6226 is an advanced PWM and linear power controller for portable applications from Intersil (Onsemi). ISL6226 integrates a fixed, selectable frequency pulse-width-modulation (PWM) controller and a 3A LDO linear regulator controller with monitoring and protection circuitry in a single 24 lead SSOP. The PWM controller regulates the battery input voltage to a user selected output voltage. Light load synchronous converter and hysteretic operation contribute to a high efficiency over a wide range of input voltage and load variation. Efficiency can be further enhanced by using the lower MOSFET’s rDS(ON) as the current sense element. Input voltage feed-forward ramp modulation, current-mode control, and internal feed-back compensation provide fast and stable handling of input voltage load transients encountered in advanced portable computer chip sets. The internal linear regulator controller provides a user selected high current output from an unregulated input with user selected current limit.

The ISL59444 is a single-output 4:1 MUX-amp with a fixed gain of 1 and a 1GHz bandwidth. It is ideal for professional video switching, HDTV, computer display routing, and other high-performance applications. The device contains logic inputs for channel selection (S0, S1), latch control signals (LE1, LE2), and a three-state output control (HIZ) for individual selection of MUX amps that share a common video output line. All logic inputs have pull-downs to ground and may be left floating.
