Product details
Overview
ISL8002AFRZ-T13 from Renesas (formerly Intersil) is a monolithic synchronous buck regulator delivering up to 2A continuous output current from a 2.7V–5.5V input, operating at 2MHz switching frequency with internal/external compensation options and integrated PMOS/NMOS power FETs. It supports 100% duty cycle operation at 1MHz (not applicable here), achieves up to 95% peak efficiency, and features PFM/PWM mode selection for light-load optimization in FPGA, LCD panel, and set-top box power rails.
For engineers reviewing the ISL8002AFRZ-T13 datasheet, ISL8002AFRZ-T13 pinout, ISL8002AFRZ-T13 application, or ISL8002AFRZ-T13 equivalent, key selection criteria include its −40°C to +125°C junction temperature rating, 2MHz fixed-frequency PWM capability, 0.6V feedback reference with ±5mV tolerance, thermal shutdown at 150°C, and 8-pin 2mm×2mm TDFN package with exposed thermal pad.
Technical Context
The ISL8002AFRZ-T13 uses peak current-mode control architecture with slope compensation (900mV/Ts) to ensure stability across wide duty cycles and load transients. Its integrated PMOS high-side switch eliminates the need for a boot capacitor, simplifying layout and reducing BOM count.
It implements dual-mode operation: PWM mode (forced continuous conduction) for low-noise, predictable EMI performance, and PFM mode (discontinuous conduction) for ultra-low quiescent current (35µA typical) during light loads-enabling extended battery life in portable applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7V to 5.5V - supports single-cell Li-ion, USB, and 3.3V/5V rail inputs without external regulators. |
| Output Current Max | 2A continuous - sufficient for core logic, DDR memory termination, and mid-power FPGA I/O banks. |
| Switching Frequency | 2MHz nominal - enables use of sub-2.2µH inductors and compact 22µF ceramic output capacitors. |
| Feedback Reference | 0.600V ±5mV - sets precise output voltage via resistor divider; supports 0.6V–VIN adjustable range. |
| Quiescent Current | 35µA typical in PFM mode - minimizes standby power loss in always-on subsystems. |
| Thermal Shutdown | 150°C with 25°C hysteresis - protects against sustained overload or poor PCB thermal design. |
| Efficiency Peak | Up to 95% - achieved at mid-load (e.g., 1.2A @ 1.8VOUT, VIN=3.3V, PFM mode). |
Pinout & Package
ISL8002AFRZ-T13 is housed in an 8-pin 2mm×2mm TDFN package with exposed thermal pad (Pin 9), optimized for high-density PCB layouts and thermal dissipation (θJA = 71°C/W, θJC = 7°C/W). The thermal pad must be connected to PGND via multiple vias for reliable operation at full 2A load.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Input power supply | Bias source for internal LDO and power stage; requires ≥10µF ceramic decoupling close to pin. |
| EN (Pin 2) | Enable control | Active-high logic input (1.4V threshold); pulls PHASE low via 100Ω when disabled for safe discharge. |
| MODE (Pin 3) | Operation mode select | Logic-high = PWM (fixed 2MHz), logic-low = PFM (variable frequency); internal 1MΩ pull-down prevents floating. |
| PG (Pin 4) | Power-good indicator | Open-drain output pulled low during soft-start or if VOUT falls below 85% or rises above 115% of setpoint. |
| COMP (Pin 5) | Error amplifier output | Connect to VIN for internal compensation (27pF/200kΩ); add RC network to GND for external loop tuning. |
| FB (Pin 6) | Voltage feedback input | Negative input of error amp; monitors output via resistor divider; used by UV/OV protection circuits. |
| PGND (Pin 7) | Power/analog ground | Common return for power stage, analog circuitry, and thermal pad; must connect directly to board GND plane. |
| PHASE (Pin 8) | Switching node | Connects to inductor; carries high di/dt switching current; discharged via 100Ω when EN = low. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated PMOS/NMOS FETs | rDS(ON) = 117mΩ (HS) / 86mΩ (LS) at VIN=5V - eliminates external MOSFETs and boot capacitor. |
| Selectably PFM/PWM operation | Reduces light-load IQ to 35µA (PFM) or maintains low-noise 2MHz clock (PWM) - selectable per system noise/efficiency trade-off. |
| Internal/external compensation | Default internal (27pF + 200kΩ) simplifies design; external RC allows custom loop response for dynamic load requirements. |
| Comprehensive protection suite | Includes overcurrent (3.5A typ), short-circuit, thermal shutdown (150°C), UVLO (2.7V), and VOUT OV/UV monitoring. |
| 100% duty cycle support (1MHz variant only) | Not applicable to ISL8002AFRZ-T13 - this part operates at 2MHz and does not support 100% duty cycle. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62864DLCR | 2A, 2.5MHz, 2.7–6V input, 0.6V ref, but requires external boot capacitor and lacks PFM mode. | Higher switching frequency enables smaller inductors but increases EMI filtering complexity; no light-load efficiency optimization. | Prefer ISL8002AFRZ-T13 when PFM operation, boot-cap-free layout, or wider temperature range (−40°C to +125°C) is required. |
| MP2143GJ-Z | 2A, 2MHz, 2.5–6V input, 0.6V ref, integrated FETs, but rated only to +85°C junction and lacks internal compensation option. | Suitable for commercial-temp consumer devices; insufficient for industrial/automotive edge cases requiring full −40°C to +125°C operation. | Choose ISL8002AFRZ-T13 for designs needing guaranteed performance across extended temperature range and simplified loop tuning. |
Compared with TPS62864DLCR and MP2143GJ-Z, the ISL8002AFRZ-T13 uniquely combines 2MHz operation, PFM/PWM mode flexibility, boot-cap-free PMOS architecture, internal/external compensation, and full −40°C to +125°C qualification-making it optimal for space-constrained, thermally demanding, and battery-sensitive embedded systems.

FAQ
What is the maximum output current and operating temperature range for the ISL8002AFRZ-T13?
The ISL8002AFRZ-T13 delivers up to 2A continuous output current and is rated for junction temperatures from −40°C to +125°C. This extended range ensures reliable operation in industrial enclosures and automotive under-hood proximity applications where ambient temperatures exceed +85°C. Its thermal pad and low rDS(ON) FETs enable full 2A delivery even at elevated ambient conditions when properly heatsinked.
Does the ISL8002AFRZ-T13 support both PWM and PFM modes, and how is mode selected?
Yes, the ISL8002AFRZ-T13 supports both PWM and PFM modes. Mode selection is controlled by the MODE pin (Pin 3): connect to VIN or logic high (>2.5V) for forced PWM operation at 2MHz; connect to GND or logic low (<0.4V) for automatic PFM mode, which reduces switching frequency under light loads to minimize quiescent current (35µA typical). An internal 1MΩ pull-down prevents undefined states if left unconnected.
What is the feedback reference voltage of the ISL8002AFRZ-T13, and how precise is it over temperature?
The ISL8002AFRZ-T13 has a nominal feedback reference voltage of 0.600V with a tolerance of ±5mV (0.595V to 0.605V) at +25°C, and ±11mV (0.589V to 0.605V) across the full −40°C to +125°C junction temperature range. This precision enables accurate output voltage setting (e.g., 1.2V ±1%) using standard 1% resistors in the FB divider network without trimming.
Can the ISL8002AFRZ-T13 operate without an external boot capacitor?
Yes, the ISL8002AFRZ-T13 integrates a PMOS high-side switch, eliminating the need for an external boot capacitor. This simplifies layout, reduces component count, and improves reliability compared to NMOS-based buck controllers. The internal PMOS architecture also enables lower gate-drive losses and inherent shoot-through protection.
What protection features are built into the ISL8002AFRZ-T13?
The ISL8002AFRZ-T13 includes overcurrent protection (3.5A typical peak limit), short-circuit protection, thermal shutdown (150°C with 25°C hysteresis), input undervoltage lockout (2.7V rising threshold), output overvoltage protection (115% VREF trip), and output undervoltage detection (85% VREF). These features safeguard downstream circuitry during fault conditions without requiring external supervision ICs.
