MAX15022ATI+

Overview

The MAX15022ATI+ is a quad-output power management IC featuring two high-performance PWM synchronous step-down regulators and two LDO controllers. It operates with an input voltage range of 2.5V to 5.5V. The switching buck converters provide output currents of 4A and 2A, supporting adjustable output voltages from 0.6V to 5.5V. The integrated switching frequency ranges from 500kHz to 4MHz. The device is housed in a 28-TQFN (5x5) package and supports operation temperatures from -40°C to +125°C.

Feature Summary

• Integrates dual synchronous buck converters and dual linear controller channels for comprehensive power delivery.
• Supports flexible switching frequencies up to 4MHz to optimize component size and transient response.
• Includes built-in sequencing capabilities to manage multi-rail power-up and power-down sequences.

Applications

• Power supply solutions for Altera FPGAs
• Power supply solutions for Xilinx FPGAs
• Quad-output DC-DC converter systems

Procurement Notes
