BM2P26CK-Z集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

General Description

The PWM Type DC/DC converter for AC/DC provides an

optimal system for all products that include an electrical

outlet.

The built-in 650 V startup circuit contributes to low power

consumption. Small-sized power supplies can be

designed with a built-in current detection resistor for

switching. Current is restricted in each cycle and

excellent performance is demonstrated in bandwidth and

transient response since current mode control is utilized.

The switching frequency is 100 kHz by a fixed method. At

light load, the switching frequency is reduced and high

efficiency is achieved. A built-in frequency hopping

function also contributes to low EMI. A built-in 800 V

super junction MOSFET makes designs easy.
