Overview

ISL8501 OBSOLETE PRODUCT NO RECOMMENDED REPLACEMENT contact our Technical Support Center at 1-888-INTERSIL or www.intersil.com/tsc Triple Output Controller with 1A Standard Buck PWM and Dual LDOs DATASHEET FN6500 Rev 1.00 July 12, 2007 The ISL8501 is a high-performance, triple output controller that provides a single, high frequency power solution for a variety of point of load applications.

The ISL8501 integrates a 1A standard buck PWM controller and switching MOSFET with two 500mA LDOs.

The PWM controller in the ISL8501 drives an internal switching N-Channel power MOSFET and requires an external Schottky diode to generate an output voltage from 0.6V to 20V.

Key Features

  • include overcurrent, undervoltage, and thermal overload protection integrated into the IC. The ISL8501 power good signal output indicates loss of regulation on the PWM output. The ISL8501 features two adjustable LDO regulators using internal PMOS transistors as pass devices. Separate enable pins (EN_LDO1, EN_LDO2) control each LDO output. A single power good signal output indicates loss of regulation on either of the two LDO outputs. Independent overcurrent and thermal fault shutdown monitors ar.
