AC/DC Drivers

PWM type DC/DC converter IC

Included 650V MOSFET

BM2P0391

●General

The PWM type DC/DC converter BM2P0391 for

●Features

 PWM frequency : 100kHz

AC/DC provides an optimum system for all products

that include an electrical outlet.

 PWM current mode method

 Frequency hopping function

BM2P0391 supports both isolated and non-isolated

devices, enabling simpler design of various types of

low-power electrical converters.

 Burst operation when load is light

 Frequency reduction function

 Built-in 650V start circuit

BM2P0391 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.

Switching frequency adopts fixed system. Since

current mode control is utilized, current is restricted in

each cycle and excellent performance is demonstrated

in bandwidth and transient response.

 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 100 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

A frequency hopping function is also on chip, which

contributes to low EMI.
