Description
The R2A20112SP is an electronic component model that falls under the product category of IC Chips. It is designed to control a boost converter for active power factor correction. The R2A20112SP adopts critical conduction mode for power factor correction, resulting in high efficiency and low switching noise through zero current switching. It also features interleaving function to improve ripple current on the input or output capacitor by 180 degrees phase shift. Additionally, this model includes built-in features such as feedback loop open detection, two-mode overvoltage protection, and overcurrent protection, enabling it to form a highly reliable power supply system with minimal external parts.
