3+1 AND 1+1 PWM Voltage Regulators for IMVP-7™ AND VR-12™ CPUs

Compliant with IMVP-7™ and VR12™, the ISL95835 and
the ISL95837 provide a complete solution for microprocessor and graphic processor core power supply.

The ISL95835 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 ISL95837 provides two single-phase Voltage...​
NCT6779D.png
1. GENERAL DESCRIPTION
The NCT6779D is a member of Nuvoton’s Super I/O product line. The NCT6779D monitors several critical parameters in PC hardware, including power supply voltages, fan speeds, and temperatures. In terms of temperature monitoring, the NCT6779D adopts the Current Mode (dual current source) and thermistor sensor approach. The NCT6779D also supports the Smart Fan control system, including “SMART FANTM I and SMART FANTM IV, which makes the system more stable and...​
