R2A20114规格书详情
Description
R2A20114 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.
