BD7672BG-GTR

General Description 

BD7672BG is a PWM controller typed 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 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.
