BD7673AG is a PWM control type DC/DC converter IC designed for AC/DC applications, suitable for both isolated and non-isolated devices. It operates within a power supply voltage range of 8.5V to 25.0V and features a fixed PWM switching frequency of 65 kHz. The device incorporates peak current control for improved bandwidth and transient response, making it suitable for low-power converter designs. Key protective functions include soft start, burst operation for low load conditions, per-cycle overcurrent limiting, VCC overvoltage protection, and output overload protection with latch functionality. The operating temperature range is -40°C to +85°C, and the IC is packaged in a compact SSOP6 format measuring 2.90mm x 2.80mm x 1.25mm. Applications include AC adapters and various household appliances, such as vacuum cleaners and air conditioners.
BD7673AG 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. BD7673AG includes various protective functions such as soft start function, burst unction, 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.
