Description
TOP257MN is an electronic component model in the category of AC DC Converters and Offline Switchers. It is a cost-effective solution that incorporates various features onto a monolithic device. These features include a 700 V power MOSFET, high voltage switched current source, PWM control, oscillator, thermal shutdown circuit, and fault protection.
Specifications and features
The TOP257MN offers several specifications and features that make it highly desirable:
- Lower system cost
- Higher design flexibility
- Multi-mode operation for maximum efficiency at all loads
- New eSIP-7F and eSIP-7C packages
- Low thermal impedance junction-to-case (2 °C per watt)
- Low height, ideal for space-limited adapters
- Simple mounting using a clip for low-cost manufacturing
- 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
- No heat sink required up to 48 W at 230 VAC
- Output overvoltage protection (OVP) with user programmable latching/non-latching shutdown
- Allows both primary and secondary sensing
- Line undervoltage (UV) detection to prevent turn-off glitches
- Line overvoltage (OV) shutdown to extend 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) to reduce transformer and power supply size
- Half frequency option for video applications
- Frequency jittering to reduce EMI filter cost
- Heat sink connected to SOURCE for low EMI
- Improved auto-restart with less than 3% of maximum power in short circuit and open-loop fault conditions
- Accurate hysteretic thermal shutdown function that automatically recovers without requiring a reset
- Fully integrated soft-start for minimum start-up stress
- Extended creepage between DRAIN and all other pins for improved field reliability
Application Scenarios
The TOP257MN is suitable for various application scenarios, including:
- Adapters where space is limited
- Ultra-low height adapter and monitor applications
- Video applications
