NJW4132U2-C-TE1

NJW4132 is a boost switching regulator IC with built-in 45V/1.75A power MOSFET. Due to the current control method, output ceramic capacitors can be easily used. A built-in phase compensation circuit enables boost applications with minimal external components. The input of an external clock can synchronize the switching frequency with the outside. In addition, the soft-start function can stabilize the startup circuit, and the over-current and over-heat protection functions can protect the circuit in abnormal situations. This product is most suitable for boosting applications such as automotive electronic accessories, OA equipment, and industrial equipment, as well as LED power supplies. Features: Current mode control can be synchronized with external clock. Wide voltage range (4.5V~40V) switching current (1.75A min.) PWM control method. Built-in phase compensation circuit can correspond to ceramic capacitor oscillation frequency (300kHz typ. (A ver.) / 700kHz typ. (B ver.) / 2.0MHz typ. (C ver.)) Soft start function (10ms typ.) Built-in low voltage error operation prevention circuit overcurrent protection function (Hiccup method) Overheating protection function standby function package ( NJW4132U2:SOT-89-5-2)​
