Power Integrations TNY277PN, Off Line Switcher Power Switch IC 7-Pin, PDIP

The TinySwitch-III family provides Low Power AC-DC Power Conversion (Up to 36.5 W)

700V Internal MOSFET Rating
Frequency Jitter Reduces EMI
EcoSmart® Low Standby/No-load Power Consumption
Latching Output Overvoltage Protection
Line Undervoltage (UV) Lockout
Selectable Current Limit

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
