Overview
The LTC3882-1 is a dual channel/dual phase, constant
frequency analog voltage mode controller for DC/DC step-
down applications. It features a PMBus compliant digital
interface for monitoring and control of important power
system parameters. The chip operates from an IC power
supplybetween3Vand13.2Vandisintendedforconversion
from VIN between 3V and 38V to output voltages between
0.5V and 5.25V. It is designed to be used in a switching
architecture with external FET drivers, including higher
level integrations such as non-isolated power blocks.
Major features include:
• Digitally Programmable Output Voltage
• Digitally Programmable Output Current Limit
• Digitally Programmable Input Voltage Supervisor
• Digitally Programmable Output Voltage Supervisors
• Digitally Programmable Switching Frequency
• Digitally Programmable On and Off Delay Times
• Digitally Programmable Soft-Start/Stop
