Product details
Overview
ISL6363CRTZ from Intersil is a dual-output multiphase PWM controller for VR12™ desktop CPU core and graphics power supplies. It integrates three gate drivers, supports 4/3/2/1-phase VR1 and 1-phase VR2, delivers 0.5% system voltage accuracy over temperature, enables DCR current sensing with single NTC compensation, and operates across 0°C to +70°C in a 48-lead 6×6 mm TQFN package.
For engineers reviewing the ISL6363CRTZ datasheet, ISL6363CRTZ pinout, ISL6363CRTZ application, or ISL6363CRTZ equivalent, this page provides verified technical context, confirmed pin functions, VR12-compliant SVID interface details, R3 modulator transient response characteristics, and validated alternative options for desktop VR design.
Technical Context
The ISL6363CRTZ implements Intel VR12™ specifications via a dual-regulator architecture: VR1 (configurable 1–4 phase) and VR2 (fixed 1-phase), sharing a single SVID serial bus. Its Robust Ripple Regulator (R3) modulator uses variable switching frequency during load transients and achieves faster settling than fixed-frequency PWM.
Both outputs support differential remote voltage sensing, lossless DCR current sensing with NTC-based thermal compensation, programmable VBOOT, IMAX/TMAX, and PS2-mode high-frequency transient compensation. The controller features adaptive body diode conduction time reduction and separate PGOOD indicators per VR.
Key Specifications

FAQ
What is the operating temperature range for the ISL6363CRTZ?
The ISL6363CRTZ is rated for commercial temperature operation from 0°C to +70°C. This range is validated per FN6898 Rev 1.00 and applies to all electrical specifications including ±0.5% system accuracy, 200–500 kHz switching frequency adjustability, and SVID interface timing. It is not rated for industrial (-40°C to +85°C) use - that specification applies only to the ISL6363IRTZ variant.
Does the ISL6363CRTZ support both DCR and resistor-based current sensing?
Yes, the ISL6363CRTZ supports both methods. For DCR sensing, it uses ISUMP/ISUMN and ISEN1–ISEN4 pins with optional NTC compensation on NTC/NTCG. For resistor sensing, it accepts shunt-based signals on the same summing inputs. The ISL6363CRTZ datasheet confirms identical OC threshold values (e.g., 50–71 µA) and droop implementation for both methods - no hardware reconfiguration is needed.
How does the R3 modulator in the ISL6363CRTZ improve transient response compared to standard PWM?
The ISL6363CRTZ R3 modulator improves transient response by dynamically increasing switching frequency during load steps - generating master clock pulses more frequently as COMP voltage rises. This yields sub-2 µs settling time for 65A steps (per Figure 1), versus >5 µs for fixed-frequency controllers. The ISL6363CRTZ achieves this without sacrificing light-load efficiency or voltage accuracy, unlike hysteretic solutions.
Can the ISL6363CRTZ be used for VR2-only applications without enabling VR1?
No - the ISL6363CRTZ requires VR_ON assertion to enable both VR1 and VR2. However, VR1 can be disabled post-startup by pulling PWM3/PWM4 high to force 1- or 2-phase operation, or by configuring SVID registers to reduce active phases. VR2 remains fully functional regardless of VR1 phase count, with independent PGOODG, IMONG, and NTCG monitoring.
What is the purpose of the PSICOMP pin on the ISL6363CRTZ?
The PSICOMP pin on the ISL6363CRTZ enables an external Type-3 compensation network during PS2/PS3 power states to boost loop gain and phase margin under high-frequency load transients. As documented on page 21 of FN6898, connecting a resistor-capacitor network from PSICOMP to VR1's output improves stability when the CPU enters deeper C-states - a function not available on standard COMP pin configurations.
