PWM Control type DC/DC converter IC - Rohm

1 Datasheet AC/DC Drivers PWM Control type DC/DC converter IC. BM1P061FJ / BM1P062FJ / BM1P101FJ / BM1P102FJ. General Features The PWM type DC/DC converter (BM1 Pxxx) for PWM frequency : 65kHz, 100kHz AC/DC provides an optimum system for all products PWM current mode method that include an electrical outlet. Frequency Hopping function BM1 Pxxx supports both isolated and non-isolated Burst operation / Frequency reduction function devices, enabling simpler design of various types of when load is light low-power electrical converters. Built-in 650V start circuit BM1 Pxxx built in a HV starter circuit that tolerates VCC pin under voltage protection 650V, it contributes to low-power consumption. VCC pin over voltage protection With switching MOSFET and current detection CS pin Open protection resistors as external devices, a higher degree of CS pin Leading-Edge-Blanking function design freedom is achieved.

2 Switching frequency Per-cycle over current protection circuit adopts fixed system. Since current mode Control is Current protection with AC voltage compensation utilized, current is restricted in each cycle and Soft start excellent performance is demonstrated in bandwidth Secondary Over current protection circuit 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 Package contributes to low EMI. SOP-J8 Pitch BM1 Pxxx also has built-in function such as soft start, (Typ) (Typ) (Typ) (Typ). burst mode, over current limiter per cycle, VCC over voltage protection and over load protection. Basic specifications Operating Power Supply Voltage Range: VCC to VH to 600V.

Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry.

5 Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings. Operating Conditions Ta=25 C .
