General Description

The MAX16064 is a fully integrated 4-channel digital power-supply controller and monitor IC that can be connected up to four power supplies to provide complete digital configurability. By interfacing to the power-supply reference input or feedback node, and the output enable, the MAX16064 takes control of the power supply to provide tracking, soft-start, sequencing, margining, and dynamic adjustment of the output voltage.

Features

♦ Accurate Voltage Output Control (AVOC) Controls Output Voltage with ±0.3 Accuracy

♦ PMBus Interface for Programming, Monitoring, Sequencing Up and Down, and Margining

♦ Output Voltage and Temperature Monitoring with Adjustable Monitor Rate

♦ Programmable Soft-Start and Soft-Stop Ramp Rates

♦ Power-Supply Control using REFIN or FB Terminals

♦ Master-Slave Clocking Option Provides Accurate Timing Reference Across Multiple Devices

♦ External EEPROM Interface for Autoboot on Power-Up

♦ 3.0V to 3.6V Operating Voltage Range

♦ 6mm x 6mm, 36-Pin TQFN Package
