AT1380A - Switching Regulator Controller

Download the AT1380A datasheet PDF (AT1380A-GlobalMixed included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for switching regulator controller.

Description

The AT1380A is a single-channel PWM control IC for DC/DC conversion with soft start function and short circuit detection.

Adjustable soft start is programmed with an external capacitor on SCP pin.

The AT1380A is ideal for up, down and fly-back conversion.

LCD Displays

Features

  • 2.5 to 15 V supply voltage operating range.
  • Low current consumption: 6 mA in operation, 1μA or less in stand-by.
  • 20 kHz to 1 MHz operation frequency range.
  • Provides a fixed output current with minimal supply voltage fluctuations by using an external resistor to set the output current.
  • Totem-pole output.
  • Built-in soft start circuit.
  • Built-in timer-latch short circuit detection and protection circuit (SCP). General.
