Product details
Overview
ISL95210HRZ-T7A from Renesas (formerly Intersil) is a high-efficiency, integrated 5V-input, 10A synchronous buck regulator in a 32-lead 6mm×4mm QFN package. It delivers ±0.6% output voltage accuracy over –10°C to +100°C, supports pin-selectable output voltages from 0.60V to 1.80V, and operates with R4™ hysteretic control-enabling stable regulation without external compensation. It is designed for point-of-load power in notebook computers and compact embedded systems requiring full 10A output at +90°C ambient without airflow.
For engineers reviewing the ISL95210HRZ-T7A datasheet, ISL95210HRZ-T7A pinout, ISL95210HRZ-T7A application, or ISL95210HRZ-T7A equivalent, key selection criteria include its 2.97V–5.5V input range, programmable switching frequency (400/533/800 kHz), margining capability, thermal robustness up to +125°C junction, and integrated protection against overcurrent, overvoltage, undervoltage, and overtemperature conditions.
Technical Context
The ISL95210HRZ-T7A implements Renesas' patented R4™ current-mode hysteretic control architecture, generating a synthetic current signal on-die to eliminate reliance on external current-sense components or loop compensation. Its balanced modulator achieves ±0.6% system output voltage accuracy across temperature without an integrator in the feedback path.
It integrates low-RDS(on) PMOS (14.8 mΩ typical) and NMOS (3.8 mΩ typical) power switches, supports three operating modes via FCCM pin (CCM, DCM, audio mode), and provides digital control of output voltage (VSEL0/VSEL1), margining (MSEL/MPCT), power-good monitoring (PG_IN/PGOOD), and frequency (FSET). All protections-including valley overcurrent trip (10–14 A), thermal shutdown (150°C), and soft-discharge (45 Ω typical)-are fully internal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Current | 10 A continuous - supports full-rated load at +90°C ambient without forced airflow. |
| Input Voltage Range | 2.97 V to 5.5 V - compatible with standard 3.3 V and 5 V rails; PVCC requires separate 5 V ±10% supply. |
| Output Voltage Accuracy | ±0.6 % over –10°C to +100°C - ensures tight regulation for CPU/GPU core rails and memory interfaces. |
| Switching Frequency | 400 / 533 / 800 kHz (pin-selectable) - enables trade-off between efficiency, size, and EMI performance. |
| Efficiency | Up to 95 % - achieved using integrated MOSFETs with low conduction losses and optimized gate drive. |
| Thermal Shutdown | 150 °C junction - protects device during overload or poor PCB thermal design; recovers at 125 °C. |
| Package | 32-lead 6 mm × 4 mm QFN with exposed thermal pad - requires thermal vias to PGND plane for +90°C operation. |
Pinout & Package
ISL95210HRZ-T7A is housed in a 32-lead, 6 mm × 4 mm, 0.5 mm pitch QFN package (Pb-free, RoHS-compliant, JEDEC MO-220 WWJJJD-3). The exposed thermal pad (T-PAD) must be soldered to a PGND copper plane with ≥9 thermal vias (0.3 mm diameter) for thermal integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| FCCM | Mode control input | Selects CCM (VCC), DCM (AGND), or audio mode (floating) - determines light-load efficiency strategy and ripple profile. |
| FSET | Frequency programming input | Sets switching frequency: GND = 400 kHz, float = 533 kHz, VCC = 800 kHz - directly impacts inductor size and EMI filtering. |
| EN | Enable logic input | Active-high enable: >2.0 V to start regulation; <1.0 V to disable - supports sequencing and system-level power management. |
| PHASE (pins 4–10) | Power switch node | Connects to output inductor - all 7 pins must be shorted on PCB to minimize parasitic inductance and ensure current sharing. |
| VIN (pins 16–18) | Main input power rail | 2.97–5.5 V supply input - bypassed with ≥10 µF ceramic capacitor to PGND; multiple pins reduce IR drop and improve current handling. |
| PGND (pins 12,13,19–23, T-PAD) | Power ground return | Low-impedance return path for switching currents - all PGND pins and T-PAD must be connected to a solid inner-layer PGND plane. |
| VSEL0 / VSEL1 | DAC voltage programming inputs | 3-state logic inputs selecting 9 preset output voltages (0.60–1.80 V) - eliminates need for external resistor divider in most applications. |
| MSEL / MPCT | Margining control inputs | Configure ±10%/±15%/±20% output voltage margining for production test - supports high-side, low-side, or nominal regulation. |
Key Features
| Feature | Design Value |
|---|---|
| R4™ Control Architecture | Eliminates external compensation components and enables stable regulation across wide LOUT/COUT ranges - reduces BOM count and layout sensitivity. |
| Integrated Power MOSFETs | 14.8 mΩ high-side PMOS + 3.8 mΩ low-side NMOS - enables 10 A output in compact footprint with no external FETs or drivers required. |
| Programmable Light-Load Efficiency | FCCM pin selects CCM (best transient response), DCM (highest light-load efficiency), or audio mode (ultra-low-noise switching) - adapts to dynamic load profiles. |
| Digital Output Voltage Margining | MSEL/MPCT pins enable ±10–20% output voltage offset - supports end-of-line functional testing without hardware changes. |
| Comprehensive Internal Protection | Valley overcurrent (10–14 A), overvoltage (112–120% VOUT), undervoltage (81–87% VOUT), and thermal shutdown (150°C) - prevents damage under fault conditions without external circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RTQ2132BGQW | 3.3–18 V input, 12 A output, 500 kHz fixed frequency, requires external compensation; smaller 4×4 mm QFN but higher RDS(on). | Targets wider input range (e.g., 12 V intermediate bus); less suitable for 5 V-only systems due to lower light-load efficiency. | Choose RTQ2132BGQW when input exceeds 5.5 V or when board space is more constrained than thermal budget. |
| TPS546D24RQFR | 4.5–18 V input, 60 A peak (dual-phase), PMBus interface, requires external inductor and compensation; larger 6×6 mm QFN. | Designed for server-grade VR13/IMVP8 compliance; supports telemetry, margining, and dynamic voltage scaling via digital interface. | Choose TPS546D24RQFR when digital control, phase interleaving, or >10 A per rail is required - not a drop-in replacement. |
Compared with RTQ2132BGQW and TPS546D24RQFR, the ISL95210HRZ-T7A offers superior thermal performance at 5 V input, eliminates compensation components via R4™ control, and delivers verified 10 A operation at +90°C ambient - making it optimal for space-constrained, thermally demanding 5 V point-of-load applications where analog simplicity and proven reliability are prioritized.

FAQ
What is the maximum ambient temperature at which ISL95210HRZ-T7A can deliver full 10A output?
The ISL95210HRZ-T7A is rated for full 10 A continuous output at +90°C ambient temperature without airflow, provided the PCB includes adequate thermal vias to the PGND plane and meets the recommended layout guidelines in AN1485. Its junction temperature limit is +125°C, and thermal shutdown activates at +150°C.
Does ISL95210HRZ-T7A require external compensation components?
No, the ISL95210HRZ-T7A uses Renesas' proprietary R4™ hysteretic control architecture, which generates a synthetic current signal internally and eliminates the need for external compensation components such as type-II or type-III error amplifier networks. This simplifies design and improves stability across varying output filter configurations.
How is output voltage programmed on ISL95210HRZ-T7A?
Output voltage on the ISL95210HRZ-T7A is programmed digitally using the VSEL0 and VSEL1 pins, which select nine preset DAC values from 0.60 V to 1.80 V. A resistor divider may be added to fine-tune within ±5% of the selected DAC value, but the internal DAC eliminates the need for external resistors in most standard applications.
What protection features are integrated into ISL95210HRZ-T7A?
The ISL95210HRZ-T7A integrates valley overcurrent protection (10–14 A trip), overvoltage (112–120% VOUT), undervoltage (81–87% VOUT), thermal shutdown (150°C), and soft-discharge (45 Ω typical) - all implemented without external components. These protections activate autonomously and recover without latch-up unless re-enabled via EN pin.
Can ISL95210HRZ-T7A operate with a 3.3 V input supply?
Yes, the ISL95210HRZ-T7A supports input voltages from 2.97 V to 5.5 V, so it is fully compatible with 3.3 V input rails. However, PVCC must still be supplied with a regulated 5 V ±10% source independent of VIN - this requirement remains unchanged regardless of VIN level.
