Power Integrations, AC-DC Converter 120 (MDCM) mA, 170 (CCM) mA, Minimum of 50 V 7-Pin, SMD LNK3204G-TL

Supports buck, buck-boost and flyback topologiesLow component-count buck converter. Selectable device current limitHigh current limit extends peak power and maximizes continuous output power. Low current limit allows the use of lowest-cost surface mount buck chokes 66 kHz operation with accurate current limit. Allows the use of low-cost off-the-shelf inductors. Reduces size and cost of magnetics and output capacitor.Low component-count buck converter Excellent load and line regulation Selectable device current limit 66 kHz operation with accurate current limit Allows the use of low-cost off-the-shelf inductors Reduces size and cost of magnetics and output capacitor Frequency jittering reduces EMI filter complexity Pin-out simplifies PCB heat sinking Auto-restart for short-circuit and open loop faults Limits power delivery to 3% of maximum during a fault
