With Integrated Switching MOSFET
BM2P060LF-Z BM2P061LF-Z
General Description
Key Specifications
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.
◼ Operating Power Supply Voltage Range
VCC Pin Voltage:
VH Pin Voltage:
DRAIN Pin Voltage:
◼ Current at Switching Operation:
11 V to 60 V
650 V (Max)
730 V (Max)
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.
