    Regulator Controller
    DESCRIPTION FEATURES n The LTC3812-5 is a synchronous step-down switching
    regulator controller that can directly step down voltages
    from up to 60V input, making it ideal for telecom and
    automotive applications. The LTC3812-5 uses a constant
    on-time valley current control architecture to deliver very
    low duty cycles with accurate cycle-by-cycle current limit
    without requiring a sense resistor. High Voltage Operation: Up to 60V
    Large 1О© Gate Drivers
    No Current Sense Resistor Required
    Dual N-Channel MOSFET Synchronous Drive
    Extremely Fast Transient Response
    В±0.5% 0.8V Voltage Reference
    Programmable Soft-Start
    Generates 5.5V Driver Supply
    Selectable Pulse-Skipping Mode Operation
    Power Good Output Voltage Monitor
    Adjustable On-Time/Frequency: tON(MIN) < 100ns
    Adjustable Cycle-by-Cycle Current Limit
    Undervoltage Lockout On Driver Supply ...
