R2A20114BFP is a boost converter IC with PFC (Power Factor Correction). Based on R2A20114AFP, R2A20114BFP has improved usability such as built-in PFC boost voltage control, current detecting amplifier with differential inputs, independent and high-functional error output pin, timer reset of OFF latch, and partial switch for PFC. 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. R2A20114BFP 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.
