R2A20274FT#GO GOLB - Brand New RENESAS IC Chips
-
Description
R2A20274FT#GO GOLB is a boost converter control IC with PFC (Power Factor Correction). 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 series supports two types of current detection methods, current detection by current transformers and that by shunt resistors, making it applicable for a variety of applications. Interleaving control of the boost converters enables the system to perform high conversion efficiency and low switching noises, and reduces ripple currents in input and output current. It integrates various kinds of protection circuits, such as the detection circuit of breaking of wire in the feedback loop, overvoltage protection circuits, overcurrent protection circuit and error output circuit, which improve the reliability of the power supply system and reduce the number of component parts on the system.
