AC/DC Drivers

PWM type DC/DC converter IC

Included 650V MOSFET

BM2PXX1 Series

●General Description

●Features

 PWM frequency : 65kHz

 PWM current mode method

The PWM type DC/DC converter (BM2PXX1) for

AC/DC provide an optimum system for all products

that include an electrical outlet.

BM2PXX1 supports both isolated and non-isolated

devices, enabling simpler design of various types of

low-power electrical converters.

BM2PXX1 built in a HV starter circuit that tolerates

650V, it contributes to low-power consumption.

With current detection resistors as external devices, a

higher degree of design freedom is achieved. Since

current mode control is utilized, current is restricted in

each cycle and excellent performance is demonstrated

in bandwidth and transient response.

 Burst operation when load is light

 Frequency reduction function

 Built-in 650V start circuit

 Built-in 650V switching MOSFET

 VCC pin under voltage protection

 VCC pin overvoltage protection

 SOURCE pin Open protection

 SOURCE pin Short protection

 SOURCE pin Leading-Edge-Blanking function

 Per-cycle over current protection circuit

 Soft start

The switching frequency is 65 kHz. At light load, the

switching frequency is reduced and high efficiency is

achieved.

 Secondary Over current protection circuit

 BR pin AC input low voltage protection

 BR pin AC input high voltage protection

A frequency hopping function is also on chip, which

contributes to low EMI.

We can design easily, because BM2PXX1 includes

the switching MOSFET.
