The ADP3155JRU-REEL from Analog Devices is a highly efficient synchronous buck switching regulator controller. It is optimized for converting a 5V main supply into the core supply voltage required by high-performance processors like the Pentium III and AMD-K6.
This controller features a 5-bit digitally programmable output voltage ranging from 1.3V to 3.5V, controlled via an internal DAC that reads the processor's voltage identification (VID) code. It utilizes a current-mode, constant off-time architecture and supports active voltage positioning for superior load transient response. The device includes short circuit protection and an overvoltage crowbar function to protect microprocessors.
Designed for desktop PC power supplies and VRM modules, the ADP3155JRU-REEL is supplied in a 20-TSSOP package. It is compliant with VRM 8.2, VRM 8.3, and VRM 8.4 standards, making it suitable for demanding processor power applications.
Key features include active voltage positioning, optimal compensation for load transient response, and a total output accuracy of 1% over temperature. The controller also incorporates two onboard linear regulator controllers.
