TinySwitch-III，Power Integration

TinySwitch-III 系列提供低功耗交流-直流功率转换（可高达 36.5W）

700V 内部 MOSFET 额定值

频率波动可减少 EMI

EcoSmart® 待机/空载功耗低

闭锁输出过电压保护

线路欠压 UV 闭锁

可选的电流限制

TinySwitch-III incorporates a 700 V power MOSFET, oscillator, high voltage switched current source, current limit user selectable and thermal shutdown circuitry. The IC family uses an ON/OFF control scheme and offers a design flexible solution with a low system cost and extended power capability.

Simple ON/OFF control, no loop compensation needed

Selectable current limit through BP/M capacitor value

Maximizes MOSFET and magnetics power delivery

Minimizes max overload power

ON-time extension

Self-biased: no bias winding or bias components

Frequency jittering reduces EMI filter costs

Pin-out simplified es heatsinking to the PCB
