BCT 811X / BCT 812X Family
SMPS Output Monitor and Linear Regulator
General Description
The BCT8113/BCT8123/BCT8115/BCT8123 is an advanced output control and monitoring circuit intended for use in the secondary side of the switching mode power supply (SMPS). It consist of a shunt regulator which is needed for the feedback control, additional linear regulator output and protection circuit. The chip can monitor the output over-voltage protection (OVP), load Over-current protection (OCP), VDD over-voltage protection, integrated thermal protection. In additional, the shut down (SHDN) and power good (PGOOD) are the control signals provided by BCT8123/ BCT8125 for any application which is incorporated with MCU or digital circuit.
The BCT8113/BCT8123/BCT8115/BCT8123 offers a quick solution to provide protection feature and increase the overall reliability to the end-user products. Besides, it offers simple circuit and cost effective solution with minimal external components and reduced PCB board space for switching power supply.
