The LTC3711EGN#PBF from Analog Devices is a synchronous step-down switching regulator controller designed for CPU power applications. It offers a wide operating input voltage range from 4V to 36V.
This controller supports a 5-bit programmable output voltage, allowing for precise voltage selection between 0.925V and 2.000V, adhering to Intel mobile VID specifications. It utilizes a valley current control architecture, enabling very low duty cycles without the need for a sense resistor. The switching frequency is adjustable via an external resistor, compensating for variations in input and output voltages.
Key features include dual N-channel MOSFET synchronous drive, power good output voltage monitoring, and programmable soft-start. Fault protection is provided through internal foldback current limiting, an output overvoltage comparator, and an optional short-circuit shutdown timer. The device is available in a 24-lead narrow SSOP package, suitable for surface mounting.
Applications include power supplies for mobile processors, notebook computers, palmtop computers, and PDAs.
