Description

This is Switching Power Controller IC.

PWM controller of high-performance current mode is specially designed for AC/DC transformer with high performance and price ratio, which supplies continuous output power of 12W within the range of wide-voltage between 85V and 265V, the output power of peak value can be up to 18W. The combination of optimized reasonable circuit design and bipolar facture technology with high performance and price ratio economizes the whole cost ultimately.

3BR1065JF datasheet

Description

The 3BR1065JF is Off-Line SMPS Current Mode Controller with integrated 650V CoolMOS® and Startup cell (frequency jitter Mode) in FullPak.

The CoolSET-F3R FullPak is the enhanced version of CoolSET-F3 and targets for the Off-Line Adapters and high power range SMPS in DVD R/W, DVD Combi, set top box, etc. It has a wide Vcc range to 25V by adopting the BiCMOS technology. With the merit of Active Burst Mode, it can achieve the lowest Standby Power Requirements (<100mW) at no load and V in = 270VAC.

Pinouts:
