AC/DC Converter IC
PWM Type DC/DC Converter IC
With Integrated Switching MOSFET
BM2P060MF-Z BM2P061MF-Z BM2P063MF-Z
General Description
The PWM Type DC/DC Converter for AC/DC provides an
optimal system for all products that include an electrical
outlet. This IC supports isolated power supply and
enables simpler designs of various low power
consumption electrical converters.
It realizes the high flexibility in power supply design
by incorporating a switching MOSFET and with external
current detection resistor.
This IC can make high efficiency power supply because it
has AC low voltage protection function and X capacitor
discharge function and operates frequency reduction,
minimum ON width adjustment and burst operation at
light load.
This IC has following various protection functions.
