BM2P161W/BM2P163W
General
The PWM type DC/DC converter series 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 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 65 kHz. At light
load, the switching frequency is reduced and high
efficiency is achieved. 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.

A: Normal operation
B: The input AC voltage is stopped. The DRAIN voltage starts to drop.
C: If the DRAIN voltage drops below a certain voltage, it becomes MAX duty and over load protection operates.
D: If the output voltage drops, the VCC pin voltage, too. And recharge operation is started.
E: The recharge operation is stopped.
F: If the DRAIN voltage drops below a certain voltage, the VCC pin voltage lowers below UVLO in order to stop
recharge operation.
