DESCRIPTION
The LTC®3888/LTC3888-1/LTC3888-2 is a PMBus-compliant
dual loop DC/DC synchronous step-down switching regulator
controller with eight expandable phases supporting
a wide range of master/slave configurations. The controller
uses constant frequency current mode architecture to
provide excellent transient response and output regulation.
Each PWM master is capable of producing output voltages
from 0.3V to 3.45V with multiple phase configurations using
DrMOS devices that provide an output current monitor.
PMBus configuration and monitoring is supported by
LTpowerPlay™ software. Programmable loop compensation
and built-in load step emulation facilitate setting bandwidth
based on input voltage and output load capacitance.
PMBus commands allow read back of input voltage, output
voltage and current, and operating status. Operating
parameters can be set via PMBus command or stored in
internal EEPROM for use at power up. Switching frequency,
phase configuration, output voltage (LTC3888/LTC3888-2),
output current limit (LTC3888-1) and device address can
also be set using external programming resistors.
