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

• Minimum Operating Voltage of 21.5 V

• Internal High Voltage Start-up Regulator

• Dual Control Outputs with Adjustable Overlap Delay

• Single Resistor Oscillator Frequency Setting

• Fast Line Feedforward

• Line Under/Over Voltage Lockout

• Dual Mode Over Current Protection

• Programmable Maximum Duty Cycle Control

• Maximum Duty Cycle Proportional to Line Voltage

• Programmable Soft Start

• Precision 5.0 V Reference

Typical Applications

• Telecommunication Power Converters

• Industrial Power Converters

• High Voltage Power Modules

• +42 V Automotive Systems

• Control Driven Synchronous Rectifier Power Converters
