DAP018C - PWM Current-Mode Controller

This page provides the datasheet information for the DAP018C, a member of the DAP018A PWM Current-Mode Controller family.

Datasheet Summary

Description

A resistive divider from the auxiliary winding to this pin sets the OPP compensation level.

voltage protection input.

Wiring a capacitor to ground helps selecting the timer duration.

This pin offers a way to adjust the frequency modulation pace.

Features

  • the device takes advantage of the auxiliary winding negative swing to let the user adjust the maximum power the converter can deliver in high line conditions (OPP). When the current setpoint falls below a given value, e. g. the output power demand diminishes, the IC automatically freezes the peak current and reduces its switching frequency down to 25 kHz. At this point, if further output power reduction occurs, the controller enters skip.
  • cycle. The DAP018X features an efficient protectiv.
