#5043: 1-Channel Intelligent Power Switch IC (TinySwitch-III, TNY277GN SMD)
R11.20
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
