Precision in Every Test, Trust in Every Result
The R2A20112 is designed by Renesas to improve efficiency and reduce noise in power supply designs. Its schematic footprint typically includes:
A critical magnetic component that stores energy.
It often controls two MOSFETs in an interleaved manner to reduce input current ripple and decrease the physical size of the boost coil.
By sensing zero current, the IC reduces switching losses in the boost diode, leading to higher overall efficiency.
