AT1388A - 6-Channel DC-DC Controller

Download the AT1388A datasheet PDF. This datasheet also covers the AT1388 variant, as both devices belong to the same 6-channel dc-dc controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The AT1388/AT1388A is a 6-channel PWM DC/DC control IC for low voltage applications with a soft start function and short circuit detection function.

Key Features

  • Low start-up power supply voltage :1.4V(CH6).
  • Wide supply voltage range from 2.5V to 6.5V (CH1~6).
  • High speed operation is possible: Maximum 1 MHz.
  • Supports for up, flyback and up/down SEPIC conversion (AT1388:CH2,3,4,5,6 AT1388A:CH2,3,4,6).
  • Supports for down and up/down Zeta conversion (AT1388:CH1 AT1388A:CH1,CH5 ).
  • Synchronized rectification on CH1,CH2.
  • Supports for inverting converter CH5.
  • Built-in On/Off function.
