NCP1560 Datasheet PDF (Full Featured Voltage Mode PWM Controller)

NCP1560 - Full Featured Voltage Mode PWM Controller

Description

Pin 1 Name Vin Application Information This pin is connected to the bulk DC input voltage supply.

A constant current source supplies current from this pin to the capacitor connected on the VAUX pin.

The charge current is typically 13.8 mA.

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.

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 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. Features http://onsemi.
