BD7672BG-GTR

Overview

The BD7672BG-GTR is a PWM controller type AC/DC converter IC designed for offline flyback switching applications. It operates with an external power MOSFET and current detection resistor, supporting both insulated and non-insulated power supply designs. The device features a fixed switching frequency of 65kHz and utilizes peak current control mode for superior bandwidth and transient response. Integrated protection circuits include soft start, burst operation for light loads, per-cycle overcurrent limiting, VCC overvoltage protection, and thermal shutdown.

Feature Summary

Supports flexible power supply design through integration with external switch MOSFETs and current detection resistors.
Incorporates built-in frequency hopping to assist in achieving low electromagnetic interference (EMI).
Provides comprehensive protection mechanisms including soft start, burst operation, and multiple fault protections.

Applications

Insulated AC/DC converters for products with AC plugs
Non-insulated AC/DC converters for products with AC plugs
Low-power DC/DC converters requiring high efficiency at light loads

Procurement Notes

Verify the specific ordering suffix and package variant against the official Rohm Semiconductor datasheet to ensure compatibility with your design requirements. Confirm that the component meets all necessary safety and regulatory standards for your target market. Check the current supply status as availability may vary by region and distributor.

Selection Notes

Select this component for designs requiring a fixed 65kHz switching frequency with peak current mode control. It is suitable for applications needing integrated EMI reduction via frequency hopping and robust protection features without external logic. Ensure the external MOSFET and transformer are compatible with the internal driver capabilities and voltage ratings.

Part Context

This part belongs to Rohm's series of AC/DC converter ICs aimed at achieving high efficiency and miniaturization. The family includes various models with different protection levels and operating characteristics, all sharing the goal of reducing light-load power consumption and integrating low-noise functions within compact packages.
