Frequently Asked Questions
What is the input voltage range of the LTC3859ALEUHF#PBF and how many regulated outputs does it provide?
The LTC3859ALEUHF#PBF accepts an input voltage from 4.5 V to 38 V and provides 3 regulated outputs: 2 synchronous buck channels and 1 synchronous boost channel, with output voltage adjustable from 0.8 V to 24 V per rail.
How does the 28 µA Burst Mode quiescent current benefit battery-powered designs using the LTC3859ALEUHF#PBF?
The LTC3859ALEUHF#PBF's 28 µA Burst Mode IQ dramatically reduces power consumption during light-load or standby conditions, extending battery runtime in portable instruments and IoT nodes where the controller spends most of its time supplying low current from a multi-rail power tree.
For which multi-rail FPGA or processor board power architectures is the LTC3859ALEUHF#PBF a suitable choice?
The LTC3859ALEUHF#PBF suits FPGA core and I/O power supplies, DSP multi-rail boards, and server daughter cards that need simultaneous 2-buck and 1-boost regulation from a 4.5 V to 38 V input bus, generating independent outputs from 0.8 V to 24 V using current-mode PWM control.
