R2A20133BSP#W5

Overview

The R2A20133BSP#W5 is a mixed-signal processor IC designed for critical conduction mode (CRM) power factor correction. It controls a boost converter to provide active power factor correction using zero-current switching to reduce switching noise. The device features second over-voltage protection (non-latching) and off-time control. It is housed in an 8-SOP package with embossed tape carrier packaging.

Feature Summary

• Implements critical conduction mode (CRM) control for single-stage PFC applications
• Utilizes zero-current switching technology to minimize switching noise
• Integrates second over-voltage protection with non-latching functionality
• Includes dedicated off-time control mechanisms

Applications

• Smart grid system power supplies
• Active power factor correction circuits
• Boost converter control systems

Procurement Notes
