STR-A6100Series

PRC, Auto Burst Standby, Current-Mode Control

Low Power Off-line SMPS Primary Switcher

Features

●

PRC〔Pulse Ratio Control〕: (8µs 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 <100mW at AC264V)

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 Standby mode, by preventing a Hiccup mode.

The Auto Bias function forces the IC to turn on before the V_CCvoltage reaches V_CC(OFF), thereby

stabilizing the entire power supply operation.

Package (DIP-8)

●

Integrated startup circuit

600V BCD process allows direct connection of the STARTUP pin to the rectified high voltage

rail. This reduces component count and improves overall efficiency.

Current mode control

Leading edge blanking

Not required the external Low-pass filter circuit which prevent the malfunction due to the leading

edge spike current.

●

Avalanche energy guaranteed MOSFET with high V_DSS

The built-in power MOSFET simplifies the surge absorption circuit since the MOSFET guarantees

the avalanche energy.
