STR-A61xx - Low Power Off-line SMPS Primary Switcher

Key Features

  • PRC Pulse Ratio Control : (8 µs fixed off-time, variable on-time) The switching frequency varies within an optimum range of 63kHz to 120kHz, according to load variations, to create a quasi-jittering, low-EMI noise operation. Auto burst standby: (No Load Consumption < 100 mW at AC 264V) Enables very low power consumption at no load. Typical results of a 5W universal input power supply are 35mW at AC110V and 43mW at AC220V. Auto bias function This function stabilizes operation during Auto Burst St.
