The ROHM BM2P104QF series PWM type DC/DC converter IC has SOP8 package and provides an optimum system for all products that include an electrical outlet. It enables simpler design of a high effective converter specializing in non-isolated devices. This IC has a built-in starter circuit that tolerates 650V, and it contributes to low power consumption. With a current detection resistor as internal device, it can be designed as small power supply. Since current mode control is utilized, current is restricted in each cycle and excellent performance is demonstrated in bandwidth and transient response. The oscillation frequency is fixed to 100kHz. In addition, a built-in super junction MOSFET which tolerates 650V makes the design easy.
