Packages The LTC®3865/LTC3865-1 are high performance dual
synchronous step-down DC/DC switching regulator
controllers that drive all N-channel synchronous power
MOSFET stages. A constant frequency current mode
architecture allows a phase-lockable frequency of up to
770kHz. Power loss and noise are minimized by operating …
