Description
TNY278PN Power Integrations Intelligent Power Switch, CV Adapter, 12W DIP-8C
TinySwitch-III, Power Integrations
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 ?exible 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 ?lter costs
Pin-out simpli?ed es heatsinking to the PCB
