64kHz integrated BJT optimized for 12Vout, 7W output

The iW1815 is an AccuSwitch™ digital PWM controller that simplifies design and lowers cost in power supplies. The iW1815 integrates a highly accurate control circuit with an 800V-rated BJT power switch. The output is optimized for a 12V output voltage at loads up to 7W and is designed to start up into large output capacitors (6,000µF). It operates in a quasi-resonant mode to optimize efficiency and also incorporates a low-power mode that achieves <30mW no-load power consumption, easily meeting global energy efficiency standards, ideal for applications such as energy-standard compliant home appliances.
