BM2P161W-Z
General Description
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.

Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the
absolute maximum ratings.
