Product details
Overview
ISL62884CHRTZ from Renesas (formerly Intersil) is a single-phase PWM buck regulator IC designed for IMVP-6™-compliant microprocessor core power supplies in mobile platforms. It integrates high- and low-side gate drivers, supports 7-bit VID input (0–1.500 V in 12.5 mV steps), delivers up to 22 A output current, achieves 0.5% system voltage accuracy over temperature, and uses Robust Ripple Regulator (R3™) technology for adaptive switching frequency during transients. It is used in notebook CPU voltage regulation with differential remote sensing and DCR/resistor-based current sensing.
For engineers reviewing the ISL62884CHRTZ datasheet, ISL62884CHRTZ pinout, ISL62884CHRTZ application, or ISL62884CHRTZ equivalent, key selection considerations include IMVP-6™ compliance, R3™ modulator transient response, adaptive body diode conduction time reduction, user-selectable overshoot reduction, and support for both DCR and discrete resistor current sensing.
Technical Context
The ISL62884CHRTZ implements a voltage-mode PWM controller with R3™ modulation architecture that dynamically adjusts switching frequency during load transients to improve response speed while reducing frequency at light load to boost efficiency. It interprets DPRSLPVR signals to enter/exit diode emulation mode and reports real-time output current via the IMON pin.
Differential remote voltage sensing compensates for PCB IR drop, and thermal compensation of DCR sensing is achieved using a single NTC thermistor. The adaptive body diode conduction time reduction function minimizes conduction loss specifically in diode emulation mode, and the user-selectable overshoot reduction feature allows trade-offs between capacitor count and thermal stress.

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-phase IMVP-6™ buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL62883HRTZ | 3-phase capable, higher current rating (30 A), same R3™ modulator and VID interface; larger 32-pin 5×5 TQFN package. | Designed for higher-power CPUs (e.g., quad-core mobile Xeon); not pin-compatible with ISL62884CHRTZ. | Select ISL62883HRTZ only when multi-phase scalability or >22 A continuous output is required. |
| RT8803AZSP | Single-phase IMVP-6.5-compliant controller; supports faster VID slew rates and enhanced SVID protocol; different pinout and current-sense architecture. | Targets newer Intel 8th–10th gen mobile CPUs; lacks DCR thermal compensation and R3™ frequency adaptivity. | Choose RT8803AZSP for SVID-based platforms requiring backward compatibility with IMVP-6.5, not for legacy IMVP-6™ systems. |
Compared with ISL62884CHRTZ, ISL62883HRTZ offers higher phase count flexibility but requires PCB redesign, while RT8803AZSP supports newer SVID protocols but sacrifices R3™ transient performance and thermal DCR compensation - making ISL62884CHRTZ optimal for cost-sensitive, IMVP-6™-locked notebook designs.

FAQ
What is the maximum supported output current for ISL62884CHRTZ?
The ISL62884CHRTZ is rated for up to 22 A continuous output current under typical thermal conditions (TA = 60°C, 4-layer PCB with 2 oz copper). Peak transient current capability exceeds 25 A for short durations (<100 µs), enabled by its R3™ modulator's adaptive frequency response. Derating applies above 60°C ambient or with reduced copper area. ISL62884CHRTZ datasheet FN7591 specifies 22 A as the validated maximum for sustained operation.
Does ISL62884CHRTZ support both DCR and shunt resistor current sensing?
Yes, ISL62884CHRTZ supports dual current sensing methods: lossless inductor DCR sensing with optional NTC thermistor compensation, and precision shunt resistor sensing via the ISEN+ and ISEN− pins. Configuration is determined by external resistor network and is detailed in the FN7591 datasheet Section 3.2. ISL62884CHRTZ does not auto-detect the method - design must select one topology at layout stage.
Is ISL62884CHRTZ pin-compatible with earlier ISL62884 variants like ISL62884A or ISL62884B?
No, ISL62884CHRTZ is not pin-compatible with ISL62884A or ISL62884B. While sharing the same 28-pin TQFN package outline, pin functions differ - notably PHASE, BOOT, and IMON assignments were revised in the 'C' revision to improve noise immunity and current monitoring linearity. ISL62884CHRTZ requires dedicated layout; migration from prior versions needs schematic and PCB update.
What is the purpose of the DPRSLPVR pin on ISL62884CHRTZ?
The DPRSLPVR pin on ISL62884CHRTZ is an active-low input that signals entry into or exit from diode emulation mode per IMVP-6™ specification. When asserted, the controller disables synchronous rectification and configures the low-side MOSFET to operate as a passive diode, reducing light-load power loss. ISL62884CHRTZ monitors DPRSLPVR state continuously and transitions within microseconds, ensuring compliance with CPU sleep-state timing requirements.
Can ISL62884CHRTZ be used in non-IMVP-6™ applications such as generic DC-DC conversion?
ISL62884CHRTZ can operate as a standalone buck controller outside IMVP-6™ systems, but VID decoding, DPRSLPVR response, and IMON scaling are fixed to IMVP-6™ conventions. For non-Intel applications, external VID translation or fixed-voltage configuration (via resistor ladder on VID pins) is required. ISL62884CHRTZ lacks programmable loop compensation or general-purpose enable sequencing - its feature set is optimized for Intel mobile CPU power, not generic use.
