NCP1560 - Full Featured Voltage Mode PWM Controller
The NCP1560 PWM controller contains all the functions and flexibility required to implement a single-ended DC/DC converter in high voltage mode control performance. The device is cost effective to reduce part of the system, several listed high voltage start-up regulators operate over a wide input range of 21.5 V to 150 V. The NCP1560 provides two control outputs, the output controls the main PWM switch with adjustable and OUT2 over-turn delay , which can control a synchronous rectifier switch or an active clamp/reset switch. Other unique features include: two-mode overcurrent protection, overvoltage lock-on/line, fast feedforward, soft-start and maximum duty cycle limit.
