产品概述

描述

The STCH02 is a PWM quasi resonant controller specifically designed for ultra-low standby power supplies. The built-in HV start-up cell with zero power consumption, the fully integrated blocks for primary side constant current output regulation and the advanced power management make this IC the best choice to build a high efficiency and ultra-low standby consumption power supply, with high overall and excellent dynamic performances.
  • 所有功能

    • Advanced power management for ultra-low standby power consumptions (under 10 mW at 230 Vac)
    • Fully integrated primary side constant current output regulation (CC)
    • 650 V embedded HV start-up circuit with zero power consumption.
    • Quasi resonant (QR) zero voltage switching (ZVS) operation
    • Automatic self-supply
    • Accurate and adjustable output OVP with autorestart after fault
    • Input voltage feedforward compensation for mains-independent CC regulation
    • Intelligent frequency jitter for EMI suppression
    • SO-8 package
