PWM type DC/DC converter IC
Included 650V MOSFET
BM2PXX1 Series
●General Description
The PWM type DC/DC converter (BM2PXX1) for
AC/DC provide an optimum system for all products
that include an electrical outlet.
BM2PXX1 supports both isolated and non-isolated
devices, enabling simpler design of various types of
low-power electrical converters.
BM2PXX1 built in a HV starter circuit that tolerates
650V, it contributes to low-power consumption.
With current detection resistors as external devices, a
higher degree of design freedom is achieved. Since
current mode control is utilized, current is restricted in
each cycle and excellent performance is demonstrated
in bandwidth and transient response.
The switching frequency is 65 kHz. At light load, the
switching frequency is reduced and high efficiency is
achieved.
A frequency hopping function is also on chip, which
contributes to low EMI.
We can design easily, because BM2PXX1 includes
the switching MOSFET.
