The LTC3858EGN-1 is a dual, 2-phase synchronous step-down switching regulator controller manufactured by Linear Technology (LT). This controller drives all N-channel synchronous power MOSFET stages and features a constant frequency current mode architecture. It allows for a phase-lockable frequency up to 850kHz and a programmable fixed frequency range of 50kHz to 900kHz.
Key electrical specifications include a wide input voltage range of 4V to 38V and a wide output voltage range from 0.8V to 24V. The device offers low operating quiescent current of 170µA (one channel on) and a very low dropout operation with a 99% duty cycle. It supports RSENSE or DCR current sensing and provides selectable continuous, pulse-skipping, or Burst Mode operation at light loads.
Packaged in a SSOP-28, the LTC3858EGN-1 is designed for applications requiring efficient power management. Its out-of-phase controller operation helps minimize input capacitor ESR and power supply induced noise. The controller also includes OPTI-LOOP® compensation to minimize COUT and features a Power Good output voltage monitor.
The input voltage range is 4V to 38V.
The output voltage range is 0.8V to 24V.
The operating temperature range is 0°C to 85°C.
The LTC3858EGN-1 is supplied in a SSOP-28 package.
The programmable fixed frequency range is 50kHz to 900kHz, and the phase-lockable frequency range is 75kHz to 850kHz.
The low operating quiescent current is 170µA with one channel on.
