Targeting battery-powered portables, the FAN302HL pulse-width modulation (PWM) controller keeps standby power low by minimizing standby input power consumption to less than 10 mW at 230 V ac. As per the company, this exceeds the efficiency standards of Energy Star Program Requirements for Computers Version 5.0. The controller integrates a 500-V JFET and employs a patented constant-current control topology that simplifies circuit design by eliminating the need for secondary constant current feedback circuitry. Protection features include cycle-to-cycle current limiting, and the gate output clamps at 15 V to protect the power MOSFET from high gate-source voltage damages. Available in an eight-pin small-outline package, the FAN302HL costs $0.50 each in lots of 1000. A datasheet is available at www.fairchildsemi.com/ds/FA/FAN302HL.pdf.
