R2A20104/114 Series

Continuous Conduction Mode Interleaving

PFC Control IC

R03DS0008EJ0301

Rev.3.01

Jan 08, 2016

Description

R2A20104/114 series is a boost converter control IC with PFC (Power Factor Correction). Employing continuous

conduction mode interleaving PFC, it performs higher efficiency and lower switching noise even for high power use.

The control of continuous conduction mode is carried out by detecting the current in power MOSFET. The R2A20114

series supports two types of current detection methods; current detection by current transformers (R2A20104SP/FP),

and that by shunt resisters (R2A20114SP/FP). So that, it can be applicable for a variety of applications. Interleaving

control of the boost converters, namely, producing 180 degrees phase shift between the output signals (GD1,2) driving

the boost converters, enables the system to perform high conversion efficiency and low switching noises and, at the

same time, to reduces ripple currents in input and output current and then this allows use of smaller components such as

boost inductors, input filters and output capacitors. R2A20114 series integrates a various kinds of protection circuits,

such as the detection circuit of breaking of wire in feedback loop, two modes of over voltage protection circuits, over

current protection circuit and error output circuit (*¹), which improve the reliability of the power supply system and

reduce the number of component parts on the system.
