The LTC3858EUFD-1 from Analog Devices is a high-performance dual, 2-phase synchronous step-down switching regulator controller. It is designed to drive all N-channel synchronous power MOSFET stages. The controller features a constant frequency current mode architecture, allowing for a phase-lockable frequency up to 850kHz.
Key electrical specifications include a wide input voltage range from 4V to 38V and a wide output voltage range from 0.8V to 24V. It offers selectable continuous, pulse-skipping, or Burst Mode operation at light loads and very low dropout operation with a 99% duty cycle. The device also features RSENSE or DCR current sensing capabilities.
Packaged in a 28-lead QFN (4mm x 5mm) with an operating temperature range of -40°C to 125°C, the LTC3858EUFD-1 is suitable for various power management applications. Its out-of-phase controller operation helps minimize input capacitance requirements and power supply induced noise.
The output voltage is adjustable from 0.8V to 24V.
The input voltage range is 4V to 38V.
It is packaged in a 28-QFN (4mm x 5mm) package.
The operating temperature range is -40°C to 125°C.
The frequency is programmable from 50kHz to 900kHz and phase-lockable from 75kHz to 850kHz.
The typical output current is 25A per channel.
The operating quiescent current is typically 170µA with one channel on.
