NCP1560
Full Featured Voltage Mode
PWM Controller
The NCP1560 PWM controller contains all the features and
flexibility needed to implement voltage ? mode control in high
performance single ended DC ? DC converters. This device cost
effectively reduces system part count with the inclusion of a high
voltage startup regulator that operates over a wide input range of

21.5 V to 150 V. The NCP1560 provides two control outputs, OUT1
which controls the main PWM switch and OUT2 with adjustable
overlap delay, which can control a synchronous rectifier switch or an
active clamp/reset switch. Other distinctive features include: two
mode over current protection, line under/overvoltage lockout, fast line
