DESCRIPTION
The LTC®3778 is a synchronous step-down switching regulator controller for computer memory, automobile and other DC/DC power supplies. The controller uses a valley current control architecture to deliver very low duty cycles without requiring a sense resistor. Operating frequency is selected by an external resistor and is compensated for variations in VIN and VOUT.

■ Sense Resistor Optional
■ True Current Mode Control
■ 2% to 90% Duty Cycle at 200kHz
■ tON(MIN) ≤ 100ns
■ Stable with Ceramic COUT
■ Dual N-Channel MOSFET Synchronous Drive
■ Power Good Output Voltage Monitor
■ ±1% 0.6V Reference
■ Adjustable Current Limit
■ Adjustable Switching Frequency
■ Programmable Soft-Start
■ Output Overvoltage Protection
■ Optional Short-Circuit Shutdown Timer
■ Micropower Shutdown: IQ ≤ 30µA
