Datasheet AC/DC Convertor IC Non-isolated Type PWM DC/DC Converter IC Built-in Switching MOSFET BM2P151S-Z General Description Key Specifications The PWM type DC/DC converter for AC/DC provides Power Supply Voltage Range an optimum system for all products that include an DRAIN Pin: 650 V (Max) electrical outlet. It enables simpler design of a high Current at Switching Operation: 850 A (Typ) effective converter specializing in non-isolation. Current at Burst Operation: 450 A (Typ) By a built-in startup circuit that tolerates 650 V, this IC Switching Frequency: 65 kHz (Typ) contributes to low power consumption. A current Operation Temperature Range: -40 C to +105 C detection resistor as internal device realizes the small MOSFET ON Resistor: 1.5 (Typ) power supply designs. Since a current mode control is utilized, the current can be restricted in each cycle and Package W (Typ) x D (Typ) x H (Max) an excellent performance is demonstrated in the DIP7K 9.27 mm x 6.35 mm x 8.63 mm bandwidth and transient response. The switching pitch 2.54 mm frequency is fixed to 65 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 makes the design easy.
