TOP203YN - Brand New Power Integrations AC DC Converters, Offline Switchers
-
Description
The TOP203YN is a high-performance electronic component belonging to the AC DC Converters and Offline Switchers product category. It is part of the TOPSwitch family, which incorporates all the essential functions required for an off-line switched mode control system. This includes a high voltage N-channel power MOSFET with a controlled turn-on gate driver, a voltage mode PWM controller with an integrated 100 kHz oscillator, a high voltage start-up bias circuit, a bandgap derived reference, a bias shunt regulator/error amplifier for loop compensation, and fault protection circuitry. The integration of these functions into a single integrated circuit reduces total cost, component count, size, weight, and increases efficiency and system reliability. The TOP203YN is designed for use in 100/110/230 VAC off-line Power Supply applications in the 0 to 100 W (0 to 50 W universal) range and 230/277 VAC off-line power factor correction (PFC) applications in the 0 to 150 W range.
Specifications and features
- Low Cost Replacement for Discrete Switchers
- 20 to 50 fewer components - cuts cost, increases reliability
- Source-connected tab and Controlled MOSFET turn-on reduce EMI and EMI filter costs
- Allows for a 50% smaller and lighter solution
- Cost competitive with linears above 5 W
Application Scenarios
The TOP203YN is highly versatile, making it suitable for various application scenarios:
- Implements Buck, Boost, Flyback, or Forward topology
- Easily interfaces with both opto and primary feedback
- Supports continuous or discontinuous mode of operation
