BM2P074KF-G
●General
The PWM type DC/DC converter (BM2P074KF-G) for
AC/DC provide an optimum system for all products
that include an electrical outlet.
BM2P074KF-G supports both isolated and
non-isolated devices, enabling simpler design of
various types of low-power electrical converters.
BM2P074KF-G built in a HV starter circuit that
tolerates 800V, it contribut 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 BM2P074KF-G
includes the switching MOSFET.
