MAX1887 - Quick-PWM Slave Controllers

This page provides the datasheet information for the MAX1887, a member of the MAX1897 Quick-PWM Slave Controllers family.

Datasheet Summary

Description

The MAX1887/MAX1897 step-down slave controllers are intended for low-voltage, high-current, multiphase DC-toDC applications.

The MAX1887/MAX1897 slave controllers can be combined with any of Maxim’s Quick-PWM™ step-down controllers to form a multiphase DC-to-DC converter.

Features

  • Synchronized to the master’s low-side gate driver, the MAX1887/MAX1897 include the Quick-PWM constant ontime controller, gate drivers for a synchronous rectifier, active current balancing, and precision current-limit circuitry. The MAX1887/MAX1897 provide the same high efficiency, ultra-low duty factor capability, and excellent transient response as other Quick-PWM controllers. The MAX1887/MAX1897 differe.

19-2188; Rev 1; 9/02 MAX1887/MAX1897 Quick-PWM Slave Controllers for Multiphase, Step-Down Supplies General Description The MAX1887/MAX1897 step-down slave controllers are intended for low-voltage, high-current, multiphase DC-toDC applications. The MAX1887/MAX1897 slave controllers can be combined with any of Maxim’s Quick-PWM™ step-down controllers to form a multiphase DC-to-DC converter. Existing Quick-PWM controllers, such as the MAX1718, function as the master controller, providing accurate output voltage regulation, fast transient response, and fault protection features.
