●General
The PWM type DC/DC converter (BM1Pxxx) for
AC/DC provides an optimum system for all products
that include an electrical outlet.
BM1Pxxx supports both isolated and non-isolated
devices, enabling simpler design of various types of
low-power electrical converters.
BM1Pxxx built in a HV starter circuit that tolerates
650V, it contributes to low-power consumption.
With switching MOSFET and current detection
resistors as external devices, a higher degree of
design freedom is achieved. Switching frequency
adopts fixed system. Since current mode control is
utilized, current is restricted in each cycle and
excellent performance is demonstrated in bandwidth
and transient response.
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.
BM1Pxxx also has built-in function such as soft start,
burst mode, over current limiter per cycle, VCC over
voltage protection and over load protection.
