AT1380A - Switching Regulator Controller

Download the AT1380A datasheet PDF. This datasheet also covers the AT1380A-GlobalMixed variant, as both devices belong to the same switching regulator controller family and are provided as variant models within a single manufacturer datasheet.

General 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

Key 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.
