BM2P159PF
General
The PWM type DC/DC converter BM2P159PF for
AC/DC provides an optimum system for all products
that include an electrical outlet. It enables simpler
design of a high effective converter specializing in
non-isolated devices.
This series has a built-in HV starter circuit that
tolerates 650V, and it contributes to low power
consumption. With a current detection resistor for
switching as internal device, it can be designed as
small power supply. 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
fixed to 100 kHz. A frequency hopping function is also
on chip, and it contributes to low EMI. In addition, a
built-in super junction MOSFET which tolerates 650V
makes the design easy.
