Analog Devices LTC3886

The LTC3886 is supported by the LTpowerPlay® software development tool with graphical user interface (GUI). The EXTVCC pin supports voltages up to 14V allowing for optimized circuit efficiency and die temperature, and for the controller output to supply the chip power. Both outputs have an independent power good indicator and FAULT function.

APPLICATIONS

The LTC®3886/LTC3886-1 is a dual PolyPhase DC/DC synchronous step-down switching regulator controller with I2C-based PMBus compliant serial interface. This controller employs a constant-frequency, current-mode architecture, with high voltage input and output capability along with programmable loop compensation.
