AC/DC Converter
PWM Type DC/DC Converter IC
Built-in a Switching MOSFET
BM2P0161 BM2P0361
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
650 V(Max)
DRAIN:
BM2P0xxx supports both isolated and non-isolated
devices, enabling simpler design of various types of low
power consumption electrical converters.
The built-in 650 V starter circuit contributes to low-power
consumption.
Circuit Current (ON)1:
BM2P0161: 0.90 mA(Typ)
BM2P0361: 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: 1.0 Ω(Typ)
BM2P0361: 3.0 Ω(Typ)
Package
W(Typ) x D(Typ) x H(Max)
DIP7K 9.20 mm x 6.35 mm x 4.30 mm pitch 2.54 mm
Design can be easily implemented because includes a
650 V switching MOSFET.
