TOP253PN - Brand New Power Integrations AC DC Converters, Offline Switchers
-
Description
TOP253PN is an electronic component model belonging to the AC DC Converters and Offline Switchers product category. It is a cost-effective solution that incorporates a 700V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, fault protection, and other control circuitry onto a monolithic device.
Specifications and features
- Lower system cost
- Higher design flexibility
- 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 35W using P, G, and M packages with universal input voltage and up to 48W at 230VAC
- 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
- 132kHz 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
- Heat sink is connected to SOURCE for low EMI
- Improved auto-restart delivers <3% of maximum power in short circuit and open loop fault conditions
- Accurate hysteretic thermal shutdown function automatically recovers without requiring a reset
- Fully integrated soft-start for minimum start-up stress
- Extended creepage between DRAIN and all other pins improves field reliability
