AAT2629IUG-1T1

The AAT2629IUG-1T1 is a power management integrated circuit designed by Analog Technologies for portable electronic devices. It features an integrated triple-output regulator, comprising two synchronous step-down converters and one low-dropout linear regulator. This design provides over-temperature and over-current protection, contributing to reliable operation.

Key electrical specifications include an input voltage range of 2.7V to 5.5V and an output voltage range from 0.6V to VIN. The device operates at a fixed switching frequency of 1.5MHz, enabling the use of smaller external components. It boasts high efficiency, reaching up to 95%, and supports output currents of up to 800mA for each of the two step-down converters and up to 300mA for the LDO output. Programmable soft-start functionality helps limit inrush current, and automatic transition between PWM and PFM modes enhances efficiency under light load conditions.

The AAT2629IUG-1T1 is supplied in a QFN33 package, offering a compact form factor suitable for space-constrained applications. Its high integration reduces PCB space and overall system costs. This component is built to Analog Technologies' high standards for quality and reliability.

Typical applications for the AAT2629IUG-1T1 include mobile phones, portable media players, handheld game consoles, personal digital assistants (PDAs), and other portable consumer electronics. It is designed for long operational life and energy efficiency, contributing to extended battery life in portable devices.
