Product details
Overview
ISL8013AIRZ-T from Renesas Electronics is a monolithic synchronous buck regulator delivering up to 3A continuous output current from a 2.8V–5.5V input, featuring 1MHz PWM switching, 97% peak efficiency, and integrated P/N-channel MOSFETs with ≤75mΩ ON-resistance at 5V VIN. It supports prebiased start-up and soft-stop output discharge for FPGA and µP core power in space-constrained portable instruments.
For engineers reviewing the ISL8013AIRZ-T datasheet, ISL8013AIRZ-T pinout, ISL8013AIRZ-T application, or ISL8013AIRZ-T equivalent, key selection criteria include its 35µA quiescent current in PFM mode, 1ms PG delay, 100% duty-cycle capability (<300mV dropout at 3A), and external synchronization support up to 4MHz for noise-sensitive DC/DC POL modules.
Technical Context
The ISL8013AIRZ-T employs current-mode PWM control with internal slope compensation and a transconductance error amplifier (20µA/V) for fast transient response and stable loop dynamics. Its dual-mode operation-selectable forced PWM or PFM via the SYNCH pin-enables optimized trade-offs between light-load efficiency and EMI performance.
Protection architecture includes hiccup-mode overcurrent limiting (4.0–5.9A switch current limit), thermal shutdown at 140°C with 25°C hysteresis, and output overvoltage monitoring via VFB comparator. The 1ms power-good timer and soft-start ramp (1ms) ensure controlled power sequencing for sensitive digital loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.8V to 5.5V - supports single-cell Li-ion, USB, and intermediate bus rails without external LDO pre-regulation. |
| Output Current | 3A continuous - sufficient for high-performance µP/FPGA core rails with margin for transient peaks. |
| Switching Frequency | 1.0 MHz (±20%) - enables use of compact 1.5µH inductors and low-ESR ceramic capacitors in <0.4in² layout. |
| Quiescent Current | 35µA in PFM mode - extends battery runtime in always-on portable instrumentation. |
| Reference Voltage | 0.800V ±10mV - provides 3% output accuracy over line/load/temperature for stable 1.2V–3.3V adjustable outputs. |
| Duty Cycle Range | 0–100% - allows ultra-low dropout operation (e.g., 3.3V out from 3.6V in) without input-to-output voltage headroom penalty. |
| Shutdown Current | <2µA - ensures negligible leakage during system sleep states. |
Pinout & Package
ISL8013AIRZ-T is housed in a RoHS-compliant, thermally enhanced 4mm × 4mm, 16-lead QFN package with exposed pad (L16.4x4). The exposed pad must be soldered to SGND for optimal thermal resistance (θJC = 3°C/W) and electrical stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 VIN | Input power supply | Accepts 2.8V–5.5V; requires local 10µF ceramic decoupling to PGND. |
| 3 VDD | Analog supply rail | Internally tied to VIN; powers control circuitry and must not be isolated. |
| 4 SYNCH | Mode/sync control | Logic-high = forced PWM; logic-low = PFM; external clock edge-triggered sync up to 4MHz. |
| 5 EN | Enable/disable control | Active-high; pulls LX low and discharges output capacitor when driven low. |
| 7 PG | Power-good indicator | Open-drain output with 1ms delay after regulation; sinks 1mA at ≤0.3V for system sequencing. |
| 8 VFB | Feedback input | Monitors output via resistor divider; 0.8V reference sets regulated voltage (e.g., 1.8V = R1/R2 = 124k/100k). |
| 13–15 LX | Switch node | Connects to inductor; carries high di/dt switching current; requires short, low-inductance PCB routing. |
| 11, 12 PGND | Power ground return | High-current return path for MOSFETs and inductor; separate from SGND to minimize noise coupling. |
| 9, 10 SGND | Signal ground reference | Reference for VFB, EN, PG, SYNCH; connected to exposed pad for thermal and noise integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated P/N-MOSFETs | ≤75mΩ total conduction loss at 5V VIN enables >95% efficiency at 2A, reducing BOM count and footprint. |
| 1ms Power-Good Timer | Guarantees reliable system reset assertion only after output stabilizes within ±3%, critical for FPGA configuration timing. |
| Soft-Stop Output Discharge | Actively discharges output capacitor on disable, preventing back-powering of upstream circuits or latch-up in multi-rail systems. |
| Selectably Forced PWM Mode | Eliminates frequency variation and associated EMI peaks in noise-sensitive applications like test equipment analog front-ends. |
| Hiccup-Mode Overcurrent Protection | Limits fault energy during sustained overload or short-circuit, enabling safe auto-recovery without thermal runaway. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS54331DR | 3A, 3.5–28V input, 570kHz fixed freq, no PFM mode, higher IQ (125µA) | Better suited for wide-input industrial supplies; lacks soft-stop discharge and prebias start-up. | Choose TPS54331DR for higher VIN applications (>5.5V); avoid for battery-powered designs requiring ultra-low IQ. |
| MP2315GJ-Z | 3A, 4.5–26V input, 1.5MHz, no SYNC pin, no PG output, 25µA IQ in skip mode | Lower cost for non-sequencing applications; missing power-good signaling and external sync capability. | Choose MP2315GJ-Z where board space is critical and PG/SYNC are unnecessary; verify thermal performance at 3A in 4mm×4mm footprint. |

FAQ
What is the maximum output current capability of the ISL8013AIRZ-T?
The ISL8013AIRZ-T delivers up to 3A continuous output current across the full operating temperature range (-40°C to +85°C), verified under recommended conditions with proper thermal layout (exposed pad connected to SGND plane). Peak switch current limit is 4.8A, supporting transient surges beyond steady-state rating.
Does the ISL8013AIRZ-T support prebiased output start-up?
Yes, the ISL8013AIRZ-T supports prebiased output start-up, allowing the output capacitor to retain residual voltage during power cycling. This prevents reverse current flow and ensures safe, glitch-free re-enabling-critical for systems with multiple interdependent power rails.
How does the ISL8013AIRZ-T manage thermal performance in high-current operation?
The ISL8013AIRZ-T uses a 4mm×4mm QFN package with an exposed thermal pad that must be soldered to the SGND plane using multiple vias. This achieves θJC = 3°C/W and θJA = 39°C/W, enabling full 3A operation without external heatsinking when PCB copper area and airflow meet datasheet layout guidelines.
What is the function of the SYNCH pin on the ISL8013AIRZ-T?
The SYNCH pin on the ISL8013AIRZ-T serves three functions: logic-high enables forced PWM mode; logic-low activates PFM mode; and an external clock signal (up to 4MHz) applied with negative-edge triggering synchronizes switching to reduce beat frequencies in multi-rail systems.
Can the ISL8013AIRZ-T operate with 100% duty cycle, and what is its practical benefit?
Yes, the ISL8013AIRZ-T supports true 100% duty cycle operation, achieving less than 300mV dropout voltage at 3A output. This enables regulation even when input voltage approaches output voltage-essential for maintaining stable core power during Li-ion battery discharge down to 3.0V.
