ISL95837IRZ

开关控制器 MULTI-PHS IMVP-7 SVD CORE CNTRLR 40LD 5X5

3+1 And 1+1 Voltage Regulator for IMVP-7/VR12™ CPUs

Compliant with IMVP-7/VR12™, the ISL95837IRZ ISL95835 provides a  complete solution for microprocessor and graphic processor  core power supply. It provides two Voltage Regulators (VRs)  with three integrated gate drivers. The first VR can be  configured as 3-, 2- or 1-phase VR while the second output is  1-phase VR, providing maximum flexibility. The two VRs share  the serial control bus to communicate with the CPU and achieve  lower cost and smaller board area compared with the two-chip  approach.
