Product Summary

The tny275g is an Energy-Efficient, Off-Line Switcher With Enhanced Flexibility and Extended Power Range. The device incorporates a 700 V power MOSFET, oscillator, high voltage switched current source, current limit (user selectable) and thermal shutdown circuitry. The tny275g uses an ON/OFF control scheme and offers a design fl exible solution with a low system cost and extended power capability. The applications of the tny275g include: Chargers/adapters for cell/cordless phones, PDAs, digital cameras, MP3/portable audio, shavers, etc, PC Standby and other auxiliary supplies, DVD/PVR and other low power set top decoders, Supplies for appliances, industrial systems, metering, etc.

Parametrics

tny275g absolute maximum ratings: (1)DRAIN Voltage: -0.3 V to 700 V; (2)DRAIN Peak Current: 400 (750) mA; (3)EN/UV Voltage: -0.3 V to 9 V; (4)EN/UV Current: 100 mA; (5)BP/M Voltage: -0.3 V to 9 V; (6)Storage Temperature: -65 to 150℃; (7)Operating Junction Temperature: -40 to 150℃; (8)Lead Temperature: 260℃.

Features

tny275g features: (1)Simple ON/OFF control, no loop compensation needed; (2)Selectable current limit through BP/M capacitor value; (3)Higher current limit extends peak power or, in open frame applications, maximum continuous power; (4)Lower current limit improves effi ciency in enclosed adapters/chargers; (5)Allows optimum TinySwitch-III choice by swapping devices with no other circuit redesign; (6)Tight I2f parameter tolerance reduces system cost; (7)Maximizes MOSFET and magnetics power delivery; (8)Minimizes max overload power, reducing cost of transformer, primary clamp & secondary components; (9)ON-time extension – extends low line regulation range/hold-up time to reduce input bulk capacitance; (10)Self-biased: no bias winding or bias components; (11)Frequency jittering reduces EMI fi lter costs; (12)Pin-out simplifi es heatsinking to the PCB; (13)SOURCE pins are electrically quiet for low EMI.
