BD7679G is a PWM controller type DC/DC converter IC 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 cycles, application excels wide bandwidth and transient response. BD7679G includes various protective functions such as soft start function, burst function, per-cycle over current limiter, VCC overvoltage protection and overload protection. An external stop pin (COMP pin) is provided, so that switching stopping can be set by external signals. The function is available as overheating protection and over voltage protection of secondary output, so on. 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 topology evaluation boards.
