TMS-SCE-1-4-S3-9 TMS-SCE-1-4-S3-9 TMSSCE14S39 Price The LTC~3720 is a synchronous step-down switching regulator controller for CPU power. An output voltage between l.05V and l.825V is selected by a 5-bit code (Intel VRM8.5 VID specification). The controller uses a valley current control architecture to deliver ve ry low duty cycles without requiring a sense resistor. Operating fre- quency is selected by an external resistor and is compen- sated for variations in VIN and VOUT.
