The TOP232YN is a high-performance off-line switcher IC from the TOPSwitch family, designed to simplify the development of switch-mode power supplies (SMPS). It integrates a high-voltage power MOSFET, PWM controller, oscillator, and multiple protection circuits into a single package. This integration reduces external component count, lowers design complexity, and improves overall system reliability, making it ideal for compact and efficient power supply designs.
This TOP232YN operates directly from rectified AC mains and is suitable for various topologies such as flyback, forward, and buck converters. It includes advanced features like auto-restart during fault conditions, thermal shutdown, and line voltage protection. The TO-220-7B package enhances thermal performance, allowing it to handle higher power levels in applications such as adapters, chargers, and consumer electronics power supplies.
Features:
- Integrated high-voltage power MOSFET.
- Built-in PWM controller and oscillator.
- Supports multiple SMPS topologies.
- Auto-restart protection during faults.
- Thermal shutdown protection.
- Line over-voltage and under-voltage protection.
- High efficiency power conversion.
- Reduced external component count.
- Frequency jittering for EMI reduction.
- Internal current limiting.
- Suitable for universal AC input.
