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 < 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 Standby mode, by preventing a Hiccup mode.
The Auto Bias function forces the IC to turn on before the V
CC
voltage reaches V
CC (OFF)
, thereby
stabilizing the entire power supply operation.
●
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.
No V
DSS
de-rating is required.
●
Various protecting functions
• Over current protection ------------ pulse by pulse
• Over voltage protection ------------ with latch
• Overload protection ---------------- Auto restart
• Thermal shutdown ------------------ with latch
