Product details
Overview
ISL62882CHRTZ from Intersil is a multiphase PWM buck regulator IC designed as a core voltage controller for IMVP-6.5™-compliant mobile CPUs and GPUs. It supports 1- or 2-phase operation, delivers 0.5% system accuracy over temperature, uses Robust Ripple Regulator (R3™) technology for variable-frequency transient response, and integrates two gate drivers in a 40-lead 5x5 TQFN package for notebook CPU/GPU power delivery.
For engineers reviewing the ISL62882CHRTZ datasheet, ISL62882CHRTZ pinout, ISL62882CHRTZ application, or ISL62882CHRTZ equivalent, key selection considerations include IMVP-6.5™ compliance, VID-programmable 0–1.500V output in 12.5mV steps, DCR/resistor current sensing, PSI#/DPRSLPVR phase shedding support, and differential remote sensing for die-voltage regulation.
Technical Context
The ISL62882CHRTZ implements a two-phase interleaved buck architecture with R3™ modulator control, enabling dynamic frequency scaling during load transients and light-load frequency reduction. It supports both CPU and GPU Vcore configurations via mode-select logic and responds to VR_ON timing, PSI#, and DPRSLPVR signals for phase add/drop and OCP threshold adjustment.
Current sensing is implemented via either lossless inductor DCR with NTC-based thermal compensation or precision shunt resistor, while differential remote sensing ensures accurate die-level voltage regulation. The split LGATE1 driver and adaptive body diode conduction time reduction optimize efficiency in diode emulation mode across the full load range.

FAQ
What is the primary function of the ISL62882CHRTZ in a mobile platform?
The ISL62882CHRTZ serves as a multiphase PWM buck regulator IC that delivers precisely regulated core voltage to mobile CPUs and GPUs. It implements IMVP-6.5™-compliant control logic-including VID decoding, PSI#-driven phase shedding, and differential remote sensing-to maintain ±0.5% output accuracy at the processor die under dynamic loads. Its R3™ modulator ensures rapid transient response critical for modern mobile workloads.
Does the ISL62882CHRTZ support both CPU and GPU Vcore configurations?
Yes, the ISL62882CHRTZ is configurable for either CPU or GPU Vcore operation via external mode-select logic and VR_ON timing alignment. It fully complies with IMVP-6.5™ specifications for both domains, supporting GPU-specific signals like DPRSLPVR and delivering optimized performance in 1-phase (GPU) or 2-phase (high-TDP CPU) modes. The FB2 function further enhances stability in single-phase GPU use cases.
How does the ISL62882CHRTZ achieve high efficiency across load conditions?
The ISL62882CHRTZ achieves high efficiency through multiple mechanisms: R3™ modulator reduces switching frequency at light loads; split LGATE1 driver minimizes dead-time losses; adaptive body diode conduction time reduction cuts reverse recovery loss in diode emulation mode; and interleaved 2-phase operation lowers RMS current in magnetics and capacitors. These features collectively enable >90% efficiency from 1A to 50A output current.
What current sensing methods does the ISL62882CHRTZ support, and why does it matter?
The ISL62882CHRTZ supports both precision shunt resistor and lossless inductor DCR current sensing. DCR sensing eliminates power loss and board space associated with resistors, while NTC-based thermal compensation corrects for copper resistance drift over temperature-critical for accurate current reporting and overcurrent protection. Resistor sensing offers higher SNR in noisy environments. This dual-mode flexibility allows designers to optimize for efficiency, cost, or signal integrity.
Is the ISL62882CHRTZ pin-compatible with earlier ISL62882 variants?
No, the ISL62882CHRTZ is not pin-compatible with non-C suffix variants such as ISL62882 or ISL62882A. The 'C' revision introduces updated timing, enhanced noise immunity, and modified PSI#/DPRSLPVR response behavior per FN7556 Rev 3.00. While the package footprint (40-lead TQFN) remains identical, signal assignments and internal logic differ-requiring schematic and layout validation before substitution. Always consult the latest ISL62882C datasheet before migration.
