Datasheet AC/DC Convertor IC PWM type DC/DC converter IC Integrated Switching MOSFET for non-Isolated type BM2P139TF/BM2P135TF/BM2P137TKF/BM2P129TF 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(BM2P13XTF/137TKF): 10.60V to 14.05V electrical outlet. It enables simpler design of a high VCC(BM2P129TF): 8.00V to 12.97V effective converter specializing in non-isolated devices. This series has a built-in HV starter circuit that DRAIN: to 650V/800V tolerates 650V/800V, and it contributes to low power consumption. With a current detection resistor for Normal Operation Current switching as internal device, it can be designed as BM2P1X9TF 0.85mA (Typ.) small power supply. Since current mode control is BM2P137TKF 1.20mA (Typ.) utilized, current is restricted in each cycle and BM2P135TF 0.95mA (Typ.) excellent performance is demonstrated in bandwidth Burst Operation Current 0.45mA(Typ.) and transient response. The switching frequency is Oscillation Frequency 100kHz(Typ.) fixed to 100 kHz. A frequency hopping function is also o o Operation Temperature Range - 40 C to +105 C on chip, and it contributes to low EMI. In addition, a MOSFET ON resistor: 4.5,7.5,9.5 (Typ.) built-in super junction MOSFET which tolerates 650V/800V makes the design easy.
