Product details
Overview
ISL8002AIRZ-T13 from Renesas (formerly Intersil) is a monolithic synchronous buck DC/DC 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 selectable PFM/PWM light-load operation. It integrates low-rDS(ON) PMOS/NMOS power switches, eliminates boot capacitor requirement, and supports 100% duty cycle at 1MHz (not applicable to this 2MHz variant).
For engineers reviewing the ISL8002AIRZ-T13 datasheet, ISL8002AIRZ-T13 pinout, ISL8002AIRZ-T13 application, or ISL8002AIRZ-T13 equivalent, key selection criteria include its 2MHz high-frequency operation enabling compact 1.0–3.3µH inductor use, ±0.5% feedback voltage accuracy (0.600V typ), integrated overcurrent/thermal/UVLO/OVP protections, and TDFN-8 2mm×2mm package with exposed thermal pad for industrial-grade thermal performance.
Technical Context
The ISL8002AIRZ-T13 uses peak current-mode control with slope compensation (900mV/Ts) for stability across wide duty cycles and load transients. Its dual-mode operation-PWM for low-noise fixed-frequency regulation and PFM for ultra-low quiescent current (35µA typ at no load)-is selected via the MODE pin, enabling optimization for either EMI-sensitive or battery-constrained systems.
It features an integrated error amplifier with transconductance of 40µA/V (internal comp) or 120µA/V (external comp), programmable soft-start (1ms ramp), and precise 0.600V ±5mV reference with <±0.1%/V line regulation. Protection includes hiccup-mode short-circuit response, thermal shutdown at 150°C with 25°C hysteresis, and negative current limiting (−1.5A typ).
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 pre-regulation. |
| Output Current Max | 2A continuous - sufficient for FPGA core, DDR memory, or SoC I/O rails in space-constrained designs. |
| Switching Frequency | 2MHz (typ) - enables use of sub-2.2µH inductors and reduces output capacitance requirements. |
| Feedback Voltage | 0.600V ±5mV - sets output from 0.6V to VIN with high accuracy for tight regulation of low-voltage cores. |
| Quiescent Current | 35µA (PFM, 2MHz) - extends battery life in always-on or low-duty-cycle portable applications. |
| Efficiency Peak | 95% - achieved at mid-load with 3.3VIN/1.8VOUT, minimizing thermal dissipation in sealed enclosures. |
| Thermal Resistance θJA | 71°C/W - validated on standard 2-layer PCB with thermal vias under exposed pad, enabling 2A operation at +85°C ambient. |
Pinout & Package
ISL8002AIRZ-T13 is housed in an 8-pin 2mm×2mm TDFN package with exposed thermal pad (Pin 9), optimized for low-inductance layout and efficient heat transfer to the PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pin 1) | Input power supply | Supplies both power stage and internal LDO bias; requires ≥10µF ceramic decoupling close to pin. |
| EN (Pin 2) | Enable control | Active-high logic (≥1.4V); pulls PHASE low via 100Ω when disabled for controlled output 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 drops below 90% or rises above 120% of setpoint. |
| COMP (Pin 5) | Error amplifier output | Tied to VIN for internal compensation; connected to RC network to GND for external loop tuning. |
| FB (Pin 6) | Feedback input | Senses output via resistor divider; referenced to 0.600V internal bandgap; used by PG and UVLO circuits. |
| PGND (Pin 7) | Power/analog ground | Common return for power stage and analog circuitry; must connect directly to PCB ground 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 |
|---|---|
| No boot capacitor required | PMOS high-side switch eliminates need for external bootstrap circuitry, reducing BOM count and layout complexity. |
| Selectably optimized efficiency | PFM mode achieves 35µA IQ for battery longevity; PWM mode ensures consistent 2MHz operation for EMI control. |
| Robust protection suite | Includes overcurrent (3.5A typ limit), thermal shutdown (150°C), UVLO (2.7V rising), and VOUT OVP/UVP (±15% thresholds). |
| Flexible compensation | Internal compensation enabled by tying COMP to VIN; external RC network allows custom loop response for diverse output caps. |
| High-accuracy regulation | 0.600V ±5mV reference with <±0.1%/V line regulation ensures stable output across input voltage variation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62864DRLR | 2.5V–5.5V input, 2A, 2.25MHz, 0.6V reference, but requires external boot capacitor and has higher 65µA IQ in PFM mode. | Less suitable for ultra-low-power battery applications due to higher quiescent current; better for noise-sensitive systems requiring tighter EMI control. | Choose TPS62864DRLR when strict EMI compliance (CISPR-22 Class B) is required and boot capacitor placement is acceptable. |
| MP2143GJ-Z | 2.5V–5.5V input, 2A, 2MHz, 0.6V reference, no boot cap, but lacks internal/external compensation flexibility and has lower 85°C max junction rating. | Not recommended for extended high-temperature industrial use; limited loop tuning capability restricts stability margin with high-ESR capacitors. | Choose MP2143GJ-Z only for cost-sensitive consumer applications where thermal derating to 1.5A at +85°C is acceptable. |
Compared with TPS62864DRLR and MP2143GJ-Z, the ISL8002AIRZ-T13 uniquely combines boot-cap-free architecture, dual-mode efficiency optimization (35µA IQ), flexible compensation, and industrial-grade thermal performance (125°C junction) in a 2mm×2mm footprint-making it optimal for space- and power-constrained embedded systems requiring long-term reliability.

FAQ
What is the maximum output current and switching frequency of the ISL8002AIRZ-T13?
The ISL8002AIRZ-T13 delivers up to 2A continuous output current and operates at a nominal switching frequency of 2MHz. This high-frequency capability allows the use of small inductors (1.0–3.3µH) and reduces output capacitance requirements, making it ideal for compact PCB layouts. The 2MHz specification is confirmed in Table 1 and Electrical Specifications (FSW = 1700–2300kHz) of the FN7888 datasheet.
Does the ISL8002AIRZ-T13 require an external boot capacitor?
No, the ISL8002AIRZ-T13 does not require an external boot capacitor because it integrates a PMOS high-side switch. This architecture eliminates the need for a charge pump or bootstrap circuit, simplifying design, reducing component count, and improving reliability. The datasheet explicitly states this advantage in the first paragraph of the overview and under "Features".
How does the MODE pin affect ISL8002AIRZ-T13 operation?
The MODE pin selects between PWM (logic high ≥2.5V) and PFM (logic low ≤0.4V) operation modes. In PWM mode, the ISL8002AIRZ-T13 maintains fixed 2MHz switching regardless of load; in PFM mode, it reduces switching frequency at light loads to minimize losses and achieve 35µA typical quiescent current. An internal 1MΩ pull-down prevents undefined states if left unconnected.
What protection features are integrated into the ISL8002AIRZ-T13?
The ISL8002AIRZ-T13 integrates overcurrent protection (3.5A typical peak limit), thermal shutdown (150°C with 25°C hysteresis), input undervoltage lockout (2.7V rising threshold), output overvoltage protection (115% VOUT trip), and output undervoltage detection (85% VOUT). These functions are detailed in the "Protections" section of the Electrical Specifications table on page 7 of FN7888.
Can the ISL8002AIRZ-T13 support 100% duty cycle operation?
No, the ISL8002AIRZ-T13 (2MHz variant) does not support 100% duty cycle operation. That feature is explicitly specified only for the 1MHz versions (ISL8002/ISL80019) in the datasheet's "100% Duty Cycle (1MHz Version)" section on page 18. The ISL8002AIRZ-T13's minimum off-time and oscillator architecture constrain it to <100% duty cycle, consistent with its 2MHz design target.
