AC/DC Drivers

PWM type DC/DC converter IC

Included 650V MOSFET

BM2PXX4 Series

●General

The PWM type DC/DC converter (BM2PXX4) for

●Features

PWM frequency : 65kHz

PWM current mode method

AC/DC provide an optimum system for all products

that include an electrical outlet.

BM2PXX4 supports both isolated and non-isolated

devices, enabling simpler design of various types of

low-power electrical converters.

BM2PXX4 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.

A frequency hopping function is also on chip, which

contributes to low EMI.
