AT1793 - 2-Channel Step-Down PWM Controller

General Description

AT1793 is a voltage-mode PWM step-down controller capable of driving loads over a wide input supply range with excellent line and load regulation characteristics.

High efficiency is obtained through the use of a low Rds(on) P-channel power switch.

Key Features

  • 4.75V to 26V supply voltage operating.
  • Efficiency up to 85%.
  • Typical frequency operation to 1MHz.
  • Voltage-mode PWM step-down regulation.
  • 1V±2% internal reference.
  • Shutdown current less than 30uA.
  • Soft-start built-in.
  • Short-circuit protection build-in.
  • QFN-16 & SOP-14 package.

AT1793 Preliminary Product Information 2-Channel Step-Down PWM Controller Features • 4.75V to 26V supply voltage operating. • Efficiency up to 85%. • Typical frequency operation to 1MHz. • Voltage-mode PWM step-down regulation. • 1V±2% internal reference. • Shutdown current less than 30uA. • Soft-start built-in. • Short-circuit protection build-in • QFN-16 & SOP-14 package. Applications •DC-DC power management. General Description AT1793 is a voltage-mode PWM step-down controller capable of driving loads over a wide input supply range with excellent line and load regulation characteristics. High efficiency is obtained through the use of a low Rds(on) P-channel power switch. It uses a fixed switching frequency up to 1MHz thus allowing smaller sized components.
