Description
1200AP40 is PWM Current−Mode Controller for Universal Off−Line Supplies Featuring Low Standby Power. A PWM (Pulse Width Modulation) Current-Mode Controller is an electronic device used in power electronic circuits to regulate the output current of a system by modulating the width of the output pulses. This type of controller is commonly used in applications such as switching power supplies, voltage regulators, motor drives, and other systems where precise control of the output current is required.
Housed in SOIC−8 or PDIP−8 package, the NCP1200A enhances the previous NCP1200 series by offering a reduced optocoupler current together with an increased drive capability. Due to its novel concept, the circuit allows the implementation of complete off−line AC−DC adapters, battery charger or a SMPS where standby power is a key parameter. […]
