常見問題解答
What is TOP232PN?
The TOP232PN is a three-terminal off-line PWM switch by Power Integrations, designed for use in low power AC-DC power supplies and DC-DC converters. It integrates a 700 V power MOSFET, a PWM control, oscillator, over-temperature protection, and fault feedback circuitry in a single package, making it suitable for various power supply applications.
How Does TOP232PN Work?
The TOP232PN operates by converting high-voltage AC power to low-voltage DC power using pulse-width modulation (PWM) control. It provides efficient power conversion with comprehensive built-in protection features, ensuring reliable and safe operation. The device's three-terminal structure simplifies the design of isolated and non-isolated power supplies.
How Many Pins does TOP232PN have and What are the Functions of the Pinout Configuration?
The TOP232PN is housed in a 7-pin through-hole PDIP (Plastic Dual In-line Package). The pinout configuration includes:
- BP/M: Bypass capacitor pin for the internal 700 V MOSFET and for control circuitry.
- FB: Feedback pin for regulating the output voltage.
- EN/UV: Enable/undervoltage lockout (UVLO) pin for on/off control and protection.
- DM: Drain pin of the internal MOSFET, also serves as the drain voltage monitoring pin for fault protection.
- COM: Return terminal for both control and power circuitry, connected to the source of the internal MOSFET and the ground of the control circuitry.
What are the Pros and Cons of TOP232PN?
Pros:
- Integrated Design: Combines power MOSFET, control, and protection features in a single package, simplifying system design.
- Efficiency: Provides high-efficiency power conversion for low power applications.
- Comprehensive Protection: Incorporates over-temperature, overvoltage, and undervoltage protection for increased reliability.
- Compact Package: The 7-pin through-hole PDIP package offers a space-saving solution for power supply designs.
- Cost-Effective: Offers a cost-effective solution for low power supply applications.
Cons:
- Power Limitation: Suitable for low power applications and may not be ideal for high-power designs.
- External Components: May require additional external components for specific application requirements.
- Temperature Consideration: Thermal management may be required for high-temperature environments.
Are There Any Equivalents/Alternatives to TOP232PN for Recommendation?
- The TOP233PN from Power Integrations is a pin-compatible alternative to the TOP232PN with extended features.
- Alternatives to the TOP232PN include the NCP1200 from ON Semiconductor and the FSDM0265RN from Fairchild Semiconductor.
