Supply original NCP1587ADR2G, PMIC - Voltage Regulators - DC DC Switching Controllers, by ON Semiconductor

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