Datasheet  
PWM Control Type  
DC/DC Converter IC for AC/DC Driver  
BD7679G  
General Description  
Key Specifications  
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.  
Power Supply Voltage range:  
8.5V to 25.0V  
0.60mA (Typ)  
0.40mA (Typ)  
65kHz (Typ)  
-40°C to +85°C  
Operating Current:  
Normal:  
Burst:  
Oscillation Frequency:  
Operating Temperature range:  
Package  
W(Typ) x D (Typ) x H (Max)  
2.90mm x 2.80mm x1.25mm  
SSOP6  
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.  
Features  
PWM frequency of 65kHz  
PWM current mode method  
Low circuit current when UVLO is ON  
(12μA at VCC=12V)  
Low circuit current without load  
(Burst operation when load is light)  
Applications  
AC adapters and household appliances (vacuum cleaners,  
humidifiers, air cleaners, air conditioners, refrigerators, IH  
cooking heaters, rice cookers, etc.)  
Built-in SW frequency hopping function  
250ns leading-edge blanking  
VCC UVLO / OVP (Auto restart)  
Per-cycle over current protection circuit  
Soft start  
Output overload protection(Auto-restart protection)  
External stop function for COMP pin (Auto restart)  
Typical Application Circuit
