Off Line Switcher 6-Pin ESIP-C
Avnet Manufacturer Part #:
TOP257EN
RoHS 6 Compliant
TOPSwitch-HX cost effectively incorporates a 700 V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection and other control circuitry onto a monolithic device.
Key Features
- Multi-mode operation maximizes efficiency at all loads
- New eSIP-7F and eSIP-7C packages
- Low thermal impedance junction-to-case (2 °C per watt)
- Low height is ideal for adapters where space is limited
- Simple mounting using a clip to aid low cost manufacturing
- Horizontal eSIP-7F package ideal for ultra low height adapter and monitor applications
- Extended package creepage distance from DRAIN pin to adjacent pin and to heat sink
- No heat sink required up to 35 W using P, G and M packages with universal input voltage and up to 48 W at 230 VAC
- Output overvoltage protection (OVP) is user programmable for latching/non-latching shutdown with fast AC reset
- Allows both primary and secondary sensing
- Line undervoltage (UV) detection prevents turn-off glitches
- Line overvoltage (OV) shutdown extends line surge limit
- Accurate programmable current limit
- Optimized line feed-forward for line ripple rejection
- 132 kHz frequency (254Y-258Y and all E/L packages) reduces transformer and power supply size
- Half frequency option for video applications
- Frequency jittering reduces EMI filter cost
