The LTC3884/LTC3884-1 from Analog Devices are dual output PolyPhase DC/DC synchronous step-down switching regulator controllers. They utilize an I2C-based PMBus compliant serial interface and a constant-frequency current mode architecture, optimized for sub-milliohm DCR sensing applications.
Key electrical specifications include a wide input voltage range of 4.5V to 38V. The output voltage can be regulated from 0.5V to 3.5V with low DCR settings, or 0.5V to 5.5V without low DCR settings. The device boasts ±0.5% output voltage accuracy over temperature. It supports accurate PolyPhase current sharing for up to 6 phases.
Features include telemetry read-back for VIN, IIN, VOUT, IOUT, temperature, and faults. It offers programmable voltage, current limit, digital soft-start/stop, sequencing, margining, and OV/UV/OC protection. The LTC3884 includes integrated N-channel MOSFET gate drivers, while the LTC3884-1 features three-state PWM pins for driving power blocks or DrMOS power stages. The controller is supported by the LTpowerPlay software development tool.
This component is AEC-Q100 qualified for automotive applications and is suitable for telecom, datacom, storage, industrial, and point-of-load applications. It is supplied in Tape & Reel packaging.
