    Synchronous Controller
    FEATURES DESCRIPTION n The LTC®3836 is a 2-phase dual output synchronous
    step-down switching regulator controller with tracking
    that drives external N-channel power MOSFETs using few
    external components. The constant-frequency current
    mode architecture with MOSFET VDS sensing eliminates
    the need for sense resistors and improves efficiency.
    The power loss and noise due to the ESR of the input
    capacitance are minimized by operating the two controllers out-of-phase. Pulse-skipping operation provides high
    efficiency at light loads. The 97% duty cycle capability
    provides low dropout operation, extending operating time
    in battery-powered systems. No Current Sense Resistors Required
    Out-of-Phase Controllers Reduce Required Input
    Capacitance
    All N-Channel Synchronous Drive
    VIN Range: 2.75V to 4.5V
    Constant-Frequency Current Mode Operation
    0.6V ±1.5% Voltage Reference
    Low Dropout Operation: 97% Duty Cycle
