Product details
Overview
ISL80020AIRZ-T from Renesas (formerly Intersil) is a monolithic synchronous buck DC/DC converter delivering up to 2A continuous output current from a 2.7V–5.5V input, operating at 2MHz switching frequency with 0.6V feedback reference and integrated PMOS/NMOS power stage. It enables compact point-of-load regulation in space-constrained telecom and industrial systems.
For engineers reviewing the ISL80020AIRZ-T datasheet, ISL80020AIRZ-T pinout, ISL80020AIRZ-T application, or ISL80020AIRZ-T equivalent, key selection criteria include its 2MHz operation for small external inductors, 100% duty cycle capability at 1MHz (not applicable here), thermal shutdown at +150°C, and integrated soft-start with 1ms ramp time.
Technical Context
The ISL80020AIRZ-T uses peak current-mode PWM control with internal slope compensation (900mV/Ts) and a transconductance error amplifier (40µA/V) clamped at 1.6V. Its control loop relies on a fixed 0.6V reference and an internal 27pF/200kΩ compensation network.
It integrates low-rDS(ON) PMOS (117mΩ) and NMOS (86mΩ) switches, eliminating the need for a boot capacitor. Protection includes overcurrent (trip at ~3.18A), short-circuit (VFB < 0.3V), negative current detection (−1.5A valley over 2 cycles), and thermal shutdown with 25°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 2.7V to 5.5V - supports single-cell Li-ion, USB, and 3.3V/5V rails without pre-regulation. |
| IOUT Max | 2A continuous - sufficient for FPGA I/O banks, DSP cores, and ASIC auxiliary rails. |
| fSW | 2MHz nominal - enables use of ≤2.2µH inductors and reduces output ripple without increasing EMI filtering burden. |
| VFB | 0.600V ±6mV - sets output voltage via resistor divider; tight tolerance ensures ±1% VOUT accuracy across temperature. |
| Efficiency | Up to 95% peak - achieved at mid-load with 3.3VIN/1.8VOUT, minimizing thermal stress in sealed enclosures. |
| Thermal Shutdown | +150°C with +125°C restart - provides robust fault recovery in high-ambient industrial environments. |
| Quiescent Current | 10–22mA at 2MHz no-load - balances light-load efficiency against control-loop responsiveness. |
Pinout & Package
ISL80020AIRZ-T is housed in an 8-pin 2mm × 2mm TDFN package with exposed thermal pad (EPAD), RoHS-compliant, moisture sensitivity level MSL3, and θJA = 71°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input power supply rail | Supplies both power stage and internal LDO; requires ≥10µF ceramic decoupling adjacent to pin. |
| EN | Enable control input | Active-high logic: device enabled when >1.4V; pulled low disables regulator and discharges output via 100Ω internal switch. |
| SGND | Signal ground reference | Must be connected directly to EPAD; separates analog sensing from power return paths. |
| PG | Power-good open-drain output | Pulled low during soft-start and fault conditions; features internal 5MΩ pull-up and 0.3V logic-low threshold. |
| FB | Feedback node for output regulation | Connects to resistor divider; monitors VOUT for regulation, UV/OV protection, and PG assertion. |
| NC | No-connect terminal | Internally unconnected; must be tied to EPAD for mechanical stability and thermal conduction. |
| PGND | Power and analog ground return | Primary ground path for high-current switching; requires low-inductance connection to PCB ground plane. |
| PHASE | Switching node | Connects to inductor; carries high di/dt current; must be routed with minimal loop area to reduce EMI. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated PMOS/NMOS power stage | Eliminates external boot capacitor and gate drivers; reduces BOM count and layout complexity. |
| 2MHz switching frequency | Enables sub-2.2µH inductors and <64mm² total solution size - ideal for ultra-compact modules. |
| Internal soft-start (1ms) | Prevents inrush current and output overshoot during power-up; eliminates need for external timing components. |
| Overcurrent & short-circuit protection | Detects >3.18A peak current and VFB < 0.3V, respectively; forces immediate P-FET turn-off and safe recovery. |
| Thermal shutdown with hysteresis | Shuts down at +150°C and resumes at +125°C - prevents thermal runaway while avoiding oscillatory cycling. |
Applications
| Telecom Point-of-Load | Industrial Sensor Node |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62864DRLR | 2.5V–5.5V input, 2A, 2.25MHz, 0.6V reference, but uses NMOS-only architecture requiring external bootstrap capacitor. | Lacks integrated PMOS; increases component count and layout sensitivity to boot node ringing. | Select when higher switching frequency (2.25MHz) and TI's WEBENCH support are prioritized over board area reduction. |
| MP2143GJ-Z | 2.5V–5.5V input, 2A, 2MHz, 0.6V reference, integrated MOSFETs, but lacks negative current protection and has lower thermal shutdown threshold (+145°C). | Missing valley-current foldback; less robust under reverse-inductor current conditions common in dynamic load steps. | Choose for cost-sensitive consumer applications where full industrial-grade fault coverage is not required. |
Compared with TPS62864DRLR and MP2143GJ-Z, the ISL80020AIRZ-T uniquely combines PMOS-based architecture (no boot cap), comprehensive protection set (including negative current detection), and proven thermal performance in 2mm×2mm TDFN - making it optimal for reliability-critical embedded POL designs.

FAQ
What is the maximum output current capability of the ISL80020AIRZ-T?
The ISL80020AIRZ-T delivers up to 2A of continuous output current across its full operating temperature range (−40°C to +85°C ambient), verified per datasheet Table 1 and confirmed by efficiency curves at 2A load in Figures 4–7. Derating applies above +85°C ambient depending on PCB thermal design; full 2A is maintained only if junction temperature remains below +150°C.
Does the ISL80020AIRZ-T require an external boot capacitor?
No, the ISL80020AIRZ-T does not require an external boot capacitor because it integrates a PMOS high-side switch. This architecture eliminates the need for charge-pump or bootstrap circuitry, reducing component count and simplifying layout - a key differentiator versus NMOS-only synchronous buck converters like the TPS62864DRLR.
What protection features are built into the ISL80020AIRZ-T?
The ISL80020AIRZ-T includes overcurrent protection (OCP) triggered at ~3.18A peak, short-circuit protection (SCP) activated when FB falls below 0.3V, negative current protection (NCP) that shuts down both FETs upon −1.5A valley current for two consecutive cycles, thermal shutdown at +150°C with +125°C restart hysteresis, and input UVLO (2.7V rising threshold). All are fully integrated and require no external components.
Can the ISL80020AIRZ-T operate at 100% duty cycle?
The ISL80020AIRZ-T is rated for 100% duty cycle operation only at 1MHz switching frequency (ISL80020 variant), not at its native 2MHz frequency. The ISL80020AIRZ-T operates exclusively at 2MHz per Ordering Information (Page 5), so 100% duty cycle is not supported for this specific part number.
What is the recommended output capacitor for the ISL80020AIRZ-T?
The datasheet recommends ≥22µF X5R or X7R ceramic output capacitors (e.g., 22µF × 2 in parallel), selected for low ESR and DC bias stability. Equation 6 (VOUTripple = ΔI / (8 × fSW × COUT)) and Equation 8 (transient overshoot) guide sizing; actual capacitance must account for up to 50% DC-bias loss - verified using manufacturer's bias-vs-capacitance curves before final selection.
