Datasheet AC/DC Convertor IC PWM type DC/DC converter IC Integrated Switching MOSFET for non-Isolated type BM2P161W-Z General Description Basic Specification The PWM type DC/DC converter series for AC/DC Power Supply Voltage Operation Range: provides an optimum system for all products that VCC: 8.00V to 18.16V include an electrical outlet. It enables simpler design of DRAIN: to 650V a high effective converter specializing in non-isolated devices. Normal Operation Current 1.50mA (Typ.) This series has a built-in HV starter circuit that Burst Operation Current 0.35mA(Typ.) tolerates 650V, and it contributes to low power Oscillation Frequency 65kHz(Typ.) consumption. With a current detection resistor as o o Operation Temperature Range - 40 C to +105 C internal device, it can be designed as small power MOSFET ON resistor: 1.9 (Typ.) supply. Since current mode control is utilized, current is restricted in each cycle and excellent performance is demonstrated in bandwidth and transient response. The switching frequency is fixed to 65 kHz. At light Package W (Typ) x D (Typ) x H (Max) load, the switching frequency is reduced and high DIP7K 9.27 mm x 6.35 mm x 8.63 mm efficiency is achieved. A frequency hopping function is pitch 2.54 mm also on chip, and it contributes to low EMI. In addition, a built-in super junction MOSFET which tolerates 650V makes the design easy. Features PWM frequency: 65kHz PWM current mode method Frequency hopping function Burst operation at light load Frequency reduction function Application Built-in 650V start circuit Households such as LED lights, air conditioners, and Built-in 650V switching MOSFET cleaners, etc.).
