R2A20134SP#W5

Overview

The R2A20134SP#W5 is an LED driver IC from Renesas designed for high-efficiency lighting applications. It features single-stage voltage step-down control to support high line-to-ground voltages. The device enables the use of low-voltage MOSFETs with voltage tolerances of 300 V to 500 V, reducing system costs compared to typical 700 V components. High-voltage control and critical-conduction mode facilitate zero-current switching at turn-on and low drain-source voltage switching. These mechanisms reduce power loss during switching, achieving a power factor of 92%.

Feature Summary

• Supports LED lighting applications with high efficiency and high power factor
• Enables selection of low-voltage MOSFETs (300 V to 500 V) to lower system cost
• Utilizes critical-conduction mode for zero-current switching at turn-on
