Datasheet AC/DC Convertor IC PWM type DC/DC converter IC Integrated Switching MOSFET for non-Isolated type BM2P109TF/BM2P159T1F/BM2P249TF General Basic Specification The PWM type DC/DC converter for AC/DC provides Power Supply Voltage Operation Range: an optimum system for all products that include an VCC(BM2P109TF) : 8.00V to 10.81V electrical outlet. It enables simpler design of a high VCC(BM2P159T1F) : 10.60V to 16.21V effective converter specializing in non-isolated devices. VCC(BM2P249TF) : 10.60V to 26.80V This series has a built-in HV starter circuit that DRAIN : to 650V tolerates 650V, and it contributes to low power consumption. With a current detection resistor for Normal Operation Current 0.85mA (Typ.) switching as internal device, it can be designed as Burst Operation Current 0.45mA(Typ.) small power supply. Since current mode control is Oscillation Frequency 100kHz(Typ.) utilized, current is restricted in each cycle and o o Operation Temperature Range - 40 C to +105 C excellent performance is demonstrated in bandwidth MOSFET ON resistor: 9.5 (Typ.) and transient response. The switching frequency is fixed to 100 kHz. A frequency hopping function is also on chip, and it contributes to low EMI. In addition, a Package built-in super junction MOSFET which tolerates 650V SOP8 5.00mm x 6.20mm x 1.71mm pitch 1.27mm makes the design easy. (Typ.) (Typ.) (Max.) (Typ.)
