»View Reliability Data
»View Material Composition » Product Change Notification |
The NCP12700 is a fixed frequency, peak current mode, PWM controller containing all of the features necessary for implementing single-ended power converter topologies. The device features a high voltage startup capable of operating over a wide input range (9 – 120/200 V MSOP10/WQFN10) and supplying at least 20 mA to provide temporary bias to VCC during system startup.
The controller offers an adjustable soft-start, input voltage UVLO protection, and an adjustable Over-Power Protection circuit which limits the total power capability of the circuit as the input voltage increases, easing the system thermal design. The UVLO pin also features a shutdown comparator which allows for an external signal to disable switching and bring the controller into a low quiescent state.
