Description

General part information

BD7672BG Series

BD7672BG is a PWM controller type DC/DC converter for AC/DC that provides an optimum system for all products that requires an electrical outlet. This product supports both isolated and non-isolated devices. IC enables simple design of low-power electrical converters. With switching MOSFET and current detection resistor as external devices, it enables more freedom in design. Since the peak current control is utilized, peak current is controlled in each cycle, application excels wide bandwidth and transient response. BD7672BG includes various protective functions such as soft start function, burst function, per-cycle over current limiter, VCC overvoltage protection and overload protection. An external latch pin (COMP pin) is provided, so that latch stopping (OFF) can be set by external signals. This function is available as overheating protection and over output voltage protection. The PWM switching frequency is fixed at 65 kHz. A frequency hopping function is included which contributes to low EMI.You can choose from a variety of power and topologyevaluation boards.
