Datasheet AC/DC Convertor PWM Type DC/DC Converter IC Built-in Switching MOSFET for Non-Isolated Type BM2P189TF BM2P209TF General Description Key Specification The PWM type DC/DC converter for AC/DC provides Power Supply Voltage Operation Range an optimum system for all products that have an VCC(BM2P189TF): 10.60 V to 19.45 V electrical outlet. It enables simpler design of a high VCC(BM2P209TF): 10.60 V to 21.62 V effective converter specializing in non-isolated devices. DRAIN: 650 V(Max) This series has a built-in starter circuit that tolerates Pulse Operation Current 0.85 mA(Typ) 650 V, and it contributes to low power consumption. Burst Operation Current 0.45 mA(Typ) With a current detection resistor as internal device, it Oscillation Frequency 100 kHz(Typ) can be designed as small power supply. Since current Operation Temperature Range -40 C to +105 C mode control is utilized, current is restricted in each MOSFET ON Resistor 9.5 (Typ) cycle and excellent performance is demonstrated in bandwidth and transient response. The oscillation Package W(Typ) x D(Typ) x H(Max) frequency is fixed to 100 kHz. A frequency hopping SOP8 5.00 mm x 6.20 mm x 1.71 mm function is also on chip, and it contributes to low EMI. In pitch 1.27 mm addition, a built-in super junction MOSFET which tolerates 650 V makes the design easy.
