Description
TOP253GN is an AC DC converter and offline switcher component designed to lower system costs while providing higher design flexibility. It 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.
Specifications and features
- Multi-mode operation maximizes efficiency at all loads.
- New eSIP-7F and eSIP-7C packages available.
- Low thermal impedance junction-to-case (2 °C per watt).
- Low height and 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.
- 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.
Application Scenarios
The TOP253GN component is ideal for AC DC converter and offline switcher applications that require efficient operation, reliable thermal management, and small size. Its low thermal impedance, low height, extended creepage distance, and optimized line feed-forward make it an excellent choice for ultra-low height adapter and monitor applications.
