DAP008 - PWM Current-Mode Controller

General Description

Pin No.

1 Pin Name Adj Function Adjust the skipping peak current Description This pin lets you adjust the level at which the cycle skipping process takes place.

Shorting this pin to ground, permanently disables the skip cycle feature.

Key Features

  • two efficient protective circuitries: 1. In presence of an overcurrent condition, the output pulses are disabled and the device enters a safe burst mode, trying to restart. Once the default has gone, the device auto.
  • recovers. 2. If an external signal (e. g. a temperature sensor) pulls the Adj pin above 3.2 V, the output pulses are immediately stopped and the DAP008 stays latched in this position. Reset occurs when the VCC collapses to ground, e. g. the user unplugs the power supply. Featur.
