Datasheet  
AC/DC Converter IC  
PWM type DC/DC converter IC  
Included a Switching MOSFET  
BM2PXX5F/BM2PXX6F/BM2PXX7F/BM2PXX8F Series  
General Description  
The PWM type DC/DC converter (BM2PXXXF)  
Basic specifications  
Operating Power Supply Voltage Range:  
for AC/DC provides an optimal system for all products  
that include an electrical outlet.  
BM2PXXXF supports both isolated and non-  
isolated devices, enabling simpler design of various  
types of low-power electrical converters.  
VCC  
DRAIN  
8.9V to 26.0V  
to 650V  
Normal Operating Current:  
The built-in 650V HV starter circuit contributes  
to low-power consumption.  
(BM2Px5xF) 0.60mA (Typ.)  
(BM2Px9xF) 0.50mA (Typ.)  
A higher degree of design freedom can be  
achieved with current detection resistors as external  
devices. Current is restricted in each cycle and  
excellent performance is demonstrated in bandwidth  
and transient response since current mode control is  
utilized. The switching frequency is 65 kHz. At light  
load, the switching frequency is reduced and high  
efficiency is achieved. A frequency hopping function  
that contributes to low EMI is also included on chip.  
Design can be easily implemented because  
includes a 650V switching MOSFET.  
Burst Operating Current:  
Oscillation Frequency:  
Operating Temperature:
