Descripción
- Typical Application for LTC3857 - Low IQ, Dual, 2-Phase Synchronous Step-Down Controller. The LTC3857 is a high performance dual step-down switching regulator controller that drives all N-channel synchronous power MOSFET stages. A constant frequency current mode architecture allows a phase-lockable frequency of up to 850kHz. Power loss and noise due to the ESR of the input capacitor ESR are minimized by operating the two controller output stages out of phase
