AC/DC Drivers

PWM Control type

DC/DC converter IC

BM1P061FJ / BM1P062FJ / BM1P101FJ / BM1P102FJ

●General

The PWM type DC/DC converter (BM1Pxxx) for

AC/DC provides an optimum system for all products

that include an electrical outlet.

BM1Pxxx supports both isolated and non-isolated

devices, enabling simpler design of various types of

low-power electrical converters.

BM1Pxxx built in a HV starter circuit that tolerates

650V, it contributes to low-power consumption.

With switching MOSFET and 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.

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.

BM1Pxxx also has built-in function such as soft start,

burst mode, over current limiter per cycle, VCC over

voltage protection and over load protection.
