The LTC3884IUK#TRPBF from Analog Devices is a dual output PolyPhase DC/DC synchronous step-down switching regulator controller. It utilizes an I2C-based PMBus compliant serial interface for digital power system management.
This controller operates with an input voltage range of 4.5V to 38V and supports output voltages from 0.5V to 3.5V with low DCR sensing, or 0.5V to 5.5V without it. It offers ±0.5% output voltage accuracy over temperature. The device employs a constant-frequency current mode architecture and supports sub-milliohm DCR current sensing for excellent performance.
Key features include programmable loop compensation, independent power good indicators, and fault functions for both outputs. The LTC3884 variant includes integrated N-channel MOSFET gate drivers, while the LTC3884-1 has three-state PWM pins for driving external power stages. It is suitable for applications in telecom, datacom, storage systems, and industrial point-of-load applications.
The LTC3884IUK#TRPBF is supplied in a 48-QFN (7x7) package and is designed for surface mount applications. It operates within a temperature range of -40°C to 125°C (TJ).
