Intersil's Multiple Output Controllers Deliver Industry-Leading Fault Protection and Reduced BOM

Wide Input Voltage Ranges and Small QFN Packages Make the ISL8501 and ISL8510 Ideal for Telecom and Handheld/Portable Designs

MILPITAS, CA--(Marketwire - November 28, 2007) - Intersil Corporation (NASDAQ: ISIL), a world leader in the design and manufacture of high-performance analog semiconductors, today announced a pair of multiple-output standard buck ICs that integrate critical power management functions to lower the number of components and save valuable board space. The triple and dual output regulators provide a single, high-efficiency power solution for a variety of point-of-load (POL) applications.

The ISL8501 and ISL8510 feature a 5V fixed input voltage capability and variable input voltage ranges up to 25V. These flexible voltage ranges make these devices ideal for a wide range of point-of-load applications such as 5V FPGA/CPLD and DSP power supplies, 12V telecom/datacom power supplies and 24V battery-powered handheld applications.

The ISL8501 is a triple output controller with two 500mA LDOs and a 1A standard PWM regulator with integrated high-side power MOSFET, while the ISL8510 is a dual output device with a single 500mA LDO and a 1A standard PWM regulator.

The ISL8501 and the ISL8510 integrate two PGOOD (Power OK) outputs for the PWM and the LDOs, along with dedicated ENABLE inputs, eliminating the need for a separate sequencer/supervisor. The enhanced fault protection features, such as undervoltage protection, thermal overload protection and overcurrent protection for both the PWM and LDO(s) make these devices ideal for a robust power supply solution.

The output voltage of the LDO(s) is fully adjustable from 0.6V to 4.2V and the PWM regulator's output voltage is adjustable form 0.6V to 20V.

The ISL8501 and ISL8510 are currently available with identical pin-to-pin configurations in 24-lead, thermally enhanced 4x4 QFN packages.
