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. The integrated power switch is optimized for excellent thermal performance up to 1A of output current. The standard buck input voltage range supports a fixed 5V or variable 6V to 25V range. The PWM regulator switches at a fixed frequency of 500kHz and utilizes simple voltage mode control with input voltage feed forward to prov...
