AC/DC Drivers
PWM type DC/DC converter IC
Included 650V MOSFET
BM2PXX3F Series
●General
●Features
The PWM type DC/DC converter (BM2PXX3F) for
AC/DC provide an optimum system for all products that
include an electrical outlet.
PWM frequency : 65kHz
PWM current mode method
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
BM2PXX3F supports both isolated and non-isolated
devices, enabling simpler design of various types of
low-power electrical converters.
BM2PXX3F 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.
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.
Secondary Over current protection circuit
