MAX15022ATI+T

Overview

The MAX15022ATI+T is a quad-output power management IC featuring two high-performance PWM synchronous step-down regulators and two LDO controllers. It operates within an input voltage range of 2.5V to 5.5V. The first buck output delivers up to 4A with adjustable voltage from 0.6V to 5.5V, while the second provides up to 2A with similar voltage adjustability. The device supports switching frequencies between 500kHz and 4MHz. It is housed in a 28-TQFN (5x5) package with an exposed pad and functions across a temperature range of -40°C to +125°C.

Feature Summary

Integrates two synchronous buck converters and two LDO controllers for comprehensive power management
Supports flexible switching frequency adjustment from 500kHz to 4MHz
Includes internal sequencing control for regulated power-up sequences
Designed for surface-mount installation in compact electronic applications

Applications

Power supply solutions for Altera FPGAs
Power supply solutions for Xilinx FPGAs
General-purpose PMIC for portable electronics requiring multiple voltage rails

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm package integrity and pin alignment before integration. Review manufacturer documentation for handling precautions related to the exposed thermal pad. Ensure compatibility with existing PCB layout constraints and thermal management requirements during procurement planning.

Selection Notes

Select this component when designing systems requiring integrated buck and LDO regulation within a single small footprint. Consider the 4A and 2A current capabilities for primary logic loads. Evaluate the 500kHz to 4MHz frequency range against EMI constraints and inductor size requirements. Verify that the 2.5V to 5.5V input range matches the system's available power source.

Part Context

This part belongs to the MAX15022 family of power management ICs designed for FPGA applications. It consolidates multiple voltage regulation functions into one device, reducing bill-of-materials count. The ATI suffix indicates tape-and-reel packaging suitable for automated assembly processes.
