Datasheet  
AC/DC Converter  
PWM Type DC/DC Converter IC  
Built-in a Switching MOSFET  
BM2P0161-Z BM2P0361-Z  
General Description  
Key Specification  
Operating Power Supply Voltage Range:  
The PWM type DC/DC converter for AC/DC provides an  
optimal system for all products that require an electrical  
outlet.  
VCC:  
8.9 V to 26.0 V  
730 V (Max)  
DRAIN:  
BM2P0161-Z and BM2P0361-Z support both isolated and  
non-isolated devices, enabling simpler design of various  
types of low power consumption electrical converters.  
The built-in 730 V starter circuit contributes to low-power  
consumption.  
Circuit Current (ON)1:  
BM2P0161-Z: 0.90 mA (Typ)  
BM2P0361-Z: 0.65 mA (Typ)  
0.30 mA (Typ)  
Circuit Current (ON)2:  
Oscillation Frequency1:  
65 kHz (Typ)  
Power supply can be designed flexibly by connecting  
current sensing resistor for the switching externally.  
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.  
Operating Ambient Temperature: -40 °C to +105 °C  
MOSFET ON Resistance:  
BM2P0161-Z: 1.0 Ω (Typ)  
BM2P0361-Z: 3.0 Ω (Typ)  
Package  
W (Typ) x D (Typ) x H (Max)  
9.27 mm x 6.35 mm x 8.63 mm  
Pitch 2.54 mm  
DIP7K  
DIP7WF  
9.35 mm x 6.35 mm x 8.10 mm  
Pitch 2.54 mm  
Design can be easily implemented because includes a  
730 V switching MOSFET.
