BM2PXX5F/BM2PXX6F/BM2PXX7F/BM2PXX8F Series
●General Description
The PWM type DC/DC converter (BM2PXXXF)
for AC/DC provides an optimal system for all products
that include an electrical outlet.
BM2PXXXF supports both isolated and non-
isolated devices, enabling simpler design of various
types of low-power electrical converters.
The built-in 650V HV starter circuit contributes
to low-power consumption.
A higher degree of design freedom can be
achieved with current detection resistors as external
devices. 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.
Design can be easily implemented because
includes a 650V switching MOSFET.
