Dual DC/DC Controller Integrates I²C/PMBus Digital Control And Programmable Loop Compensation

Dual DC/DC Controller Integrates I²C/PMBus Digital Control And Programmable Loop Compensation
Linear Technology Corp.

The LTC3886 60V input dual output synchronous step-down dc/dc controller with programmable loop compensation and I²C-based PMBus interface employs a constant-frequency, current-mode architecture with programmable output voltage up to 13.8V. The device can be configured for dual or single output and is stackable up to six phases to support load current as high as 120A. Interleaved clock phasing for 2, 3, 4 or 6 phases reduces the input and output ripple, thereby reducing input and output capacitance. This device is supported by LTpowerPlay software development tools with a graphical user interface. In addition to delivering power to a point-of-load, the LTC3886 features configurability and telemetry monitoring of power and power management parameters over PMBus. Housed in a 7 mm x 8 mm QFN-52 package, price for the LTC3886 is $6.35 each/1,000. For a datasheet, visit http://www.linear.com/product/LTC3886
