ROHM BM2P134Q-Z, 1-Channel, DC-DC DC-DC Converter 7-Pin, DIP

The PWM type DC/DC converter for AC/DC 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 series has a built-in starter circuit that tolerates 650 V (BM2P137Q) / 800 V (BM2P137QK), and it contributes to low power consumption. With a current detection resistor for switching 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 100 kHz A frequency hopping function is also on chip, and it contributes to low EMI. In addition, a built-in super junction MOSFET which tolerates 650 V / 800 V makes the design easy.
