Description
General part information
LTC3718 Series
The LTC3718 is a high current, high efficiency synchronous switching regulator controller for DDR and QDR™memory termination. It operates from an input as low as 1.5V and provides a regulated output voltage equal to (0.5)VIN. The controller uses a valley current control architecture to enable high frequency operation with very low on-times without requiring a sense resistor. Operating frequency is selected by an external resistor and is compensated for variations in VINand VOUT. The LTC3718 uses a pair of standard 5V logic level N-channel external MOSFETs, eliminating the need for expensive P-channel or low threshold devices.Forced continuous operation reduces noise and RF interference. Fault protection is provided by internal foldback current limiting, an output overvoltage comparator and an optional short-circuit timer. Soft-start capability for supply sequencing can be accomplished using an external timing capacitor. OPTI-LOOP®compensation allows the transient response to be optimized over a wide range of loads and output capacitors.ApplicationsBus Termination: DDR/QDR Memory, SSTL, HSTL,...Servers, RAID SystemsDistributed Power SystemsSynchronous Buck with General Purpose Boost
