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 start-up 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

over-lap 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/over voltage lockout, fast

line feedforward, soft start and a maximum duty cycle limit.
