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.

Startup

V_FB/OLP

GND

●

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.

Drain

V_CC

S/OCP

No V_DSSde-rating is required.
