BIT3251 Datasheet PDF – Low Cost PWM Controller – BiTEK

Part Number: BIT3251

Function: Low Cost PWM Controller

Manufacturer: BiTEK


BIT3251 datasheet



The BIT3251 is a high frequency PWM controller integrates required fuctions for boost conversion in a small SOP-8 package. A low 0.2V feedback voltage and over voltage protection make the BIT3251 be an ideal controller for LED backlight supplies. CMOS process greatly reduces the operating current when comparing to similar products.

TNY264PN Datasheet – Low Power Off-line Switcher – Power

Part Number: TNY264PN

Function: AC/DC Converters 6W 85-265 VAC 9W/230 VAC

Manufacturers : Power Integrations





TinySwitch™-II integrates a 700 V power MOSFET, oscillator, high voltage switched current source, current limit and thermal shutdown circuitry onto a monolithic device. The start-up and operating power are derived directly from the voltage on the DRAIN pin, eliminating the need for a bias winding and associated circuitry. In addition, the TinySwitch-II devices incorporate auto-restart, line undervoltage sense, and frequency jittering. An innovative design minimizes audio frequency components in the simple ON/OFF control scheme to practically eliminate audible noise with standard taped/varnished transformer construction.





Product Highlights

1. TinySwitch-II Features Reduce System Cost

(1) Fully integrated auto-restart for short circuit and open loop fault protection – saves external component costs

(2) Built-in circuitry practically eliminates audible noise with ordinary dip-varnished transformer

(3) Programmable line undervoltage detect feature prevents power on/off glitches – saves external components

(4) Frequency jittering dramatically reduces EMI (~10 dB) – minimizes EMI filter component costs

(5) 132 kHz operation reduces transformer size – allows use of EF12.6 or EE13 cores for low cost and small size

(6) Very tight tolerances and negligible temperature variation on key parameters eases design and lowers cost

(7) Lowest component count switcher solution

(8) Expanded scalable device family for low system cost
