BM2P01A Datasheet, PDF (1/24 Pages) Rohm – PWM Type DC/DC converter IC Integrated Switching MOSFET

Datasheet
AC/DC Convertor IC
PWM Type DC/DC converter IC
Integrated Switching MOSFET
BM2PXXA/BM2PXXB Series
General Description
The PWM Type DC/DC converter for AC/DC provides an
optimal system for all products that include an electrical
outlet. BM2PXXA/BM2PXXB supports both isolated and
non-isolated devices, enabling simpler design of various
Types of high-efficiency electrical converters.
The built-in starter circuit which withstand 650V pressure
contributes to low-power consumption. Design can be
easily implemented because includes a sensing resistor.
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 100 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 Super
Junction MOSFET.
