Description
- Typical Application for LTC3858-2 - Low IQ, Dual 2-Phase Synchronous Step-Down Controller. The LTC3858-2 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 input capacitor ESR are minimized by operating the two controller outputs out of phase
