Product details
Overview
ISL80030AFRZ-T from Renesas (formerly Intersil) is a monolithic 3A synchronous buck DC/DC converter optimized for space-constrained POL applications. It operates from 2.7V–5.5V input, delivers up to 3A continuous output, uses peak current-mode PWM control at 2MHz switching frequency, and integrates low-rDS(ON) PMOS/NMOS power switches - eliminating the need for a boot capacitor. It powers core logic in game consoles and industrial instrumentation.
For engineers reviewing the ISL80030AFRZ-T datasheet, ISL80030AFRZ-T pinout, ISL80030AFRZ-T application, or ISL80030AFRZ-T equivalent, key selection criteria include its 2MHz PWM operation for fast transient response, 100% duty cycle capability, integrated soft-start/soft-stop, power-good signaling, and thermal/overcurrent protection - all in an ultra-compact 2mm×2mm DFN package.
Technical Context
The ISL80030AFRZ-T implements peak current-mode PWM control with slope compensation (900mV/Ts) and a transconductance error amplifier (40µA/V) clamped at 1.6V. Its P-channel high-side MOSFET (70mΩ @ 5V) enables 100% duty cycle operation and removes boot capacitor requirements.
It features dedicated protection circuits: overcurrent detection via CSA (300mV/A gain), zero-cross sensing for negative current limit (–2A threshold), thermal shutdown at +150°C with 25°C hysteresis, and VFB-based short-circuit protection that reduces oscillator frequency to 1/3 during fault.
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 | Up to 3A continuous - sufficient for FPGA I/O banks, microcontroller cores, and ASIC subsystems. |
| Switching Frequency | 2MHz nominal - enables use of ≤2.2µH inductors and reduces output ripple without increasing ESR requirements. |
| Feedback Voltage | 0.600V ±1% - sets precise output voltage via external resistor divider; stable across –40°C to +125°C. |
| Quiescent Current | 10–22mA (no load) - optimized for active-system efficiency; significantly lower than legacy 1MHz variants under light load. |
| Efficiency Peak | Up to 95% - achieved at mid-load with 3.3VIN/1.8VOUT, minimizing thermal dissipation in sealed enclosures. |
| Duty Cycle Range | 0% to 100% - supports dropout operation down to VOUT = VIN, critical for battery-end-of-life scenarios. |
Pinout & Package
ISL80030AFRZ-T is housed in an 8-lead 2mm×2mm DFN package with exposed thermal pad (EPAD), RoHS-compliant and MSL3 rated. The EPAD must be soldered to PGND for optimal thermal performance (θJC = 7°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pins 1,2) | Input power supply and internal LDO bias source | Requires ≥10µF ceramic decoupling close to pins; powers both power stage and control circuitry. |
| EN (Pin 3) | Enable logic input | Active-high: device enabled when >1.4V; pulls output low via 100Ω discharge path when disabled. |
| PG (Pin 4) | Power-good open-drain output | Asserts low during soft-start or if VOUT falls outside 85–117% regulation window; includes 5MΩ internal pull-up. |
| FB (Pin 5) | Feedback node for voltage regulation | Connects to resistor divider; monitors output and feeds error amplifier; used by UV/OV/SCP protection circuits. |
| PGND (Pins 6,7) | Power and analog ground reference | Must connect directly to PCB ground plane; shared return for high-current paths and signal references. |
| PHASE (Pin 8) | Switching node between MOSFETs | Drives external inductor; discharged via internal 100Ω resistor during shutdown to prevent output ringing. |
| EPAD | Exposed thermal pad | Electrically connected to PGND; requires multiple vias to inner ground plane for thermal and electrical integrity. |
Key Features
| Feature | Design Value |
|---|---|

| 100% duty cycle operation | Maintains regulation even as input drops to output level - extends runtime in battery-powered systems. |
| Integrated soft-start & soft-stop | Controls inrush current during startup (0.39–1.36ms ramp) and prevents output overshoot during shutdown. |
| Comprehensive protection suite | Includes overcurrent (4.5A typ), thermal shutdown (+150°C), negative current (–2A), and VFB-based short-circuit detection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL80030FRZ-T | 1MHz PWM switching frequency; higher quiescent current (7–15mA); identical pinout and package. | Better light-load efficiency in always-on monitoring systems; larger inductors required. | Select when EMI filtering is prioritized over size or when 1MHz timing aligns with system clock domains. |
| TPS62864DRLR | 2.5V–5.5V input; 4A output; 2.25MHz switching; integrated compensation; different pinout (12-pin WSON). | Higher current capability and smaller solution size but requires PCB redesign and new layout validation. | Choose for next-gen designs needing >3A or tighter output tolerance; not drop-in compatible with ISL80030AFRZ-T. |
Compared with ISL80030FRZ-T, the ISL80030AFRZ-T delivers faster transient response and smaller magnetics due to its 2MHz operation, while the TPS62864DRLR offers higher current and tighter regulation but mandates layout changes and lacks 100% duty cycle support.

FAQ
What is the switching frequency of the ISL80030AFRZ-T?
The ISL80030AFRZ-T operates at a fixed 2MHz nominal switching frequency, as confirmed in Table 1 and Electrical Specifications (page 8). This enables compact magnetic design and fast transient response. Frequency tolerance is ±15% (1.7–2.3MHz) across temperature and input voltage, ensuring predictable EMI behavior in noise-sensitive applications.
Does the ISL80030AFRZ-T require an external boot capacitor?
No, the ISL80030AFRZ-T does not require an external boot capacitor because it uses a P-channel MOSFET for the high-side switch. This architecture eliminates the need for charge-pump or bootstrap circuitry, reducing component count and PCB area - a key differentiator from NMOS-based synchronous buck controllers.
What protection features are integrated into the ISL80030AFRZ-T?
The ISL80030AFRZ-T integrates overcurrent protection (trip at ~4.5A), thermal shutdown (+150°C), negative current limiting (–2A), short-circuit detection (via VFB < 0.3V), VIN undervoltage lockout (2.7V rising), and VOUT overvoltage protection (117% nominal). All protections are fully autonomous and require no external components.
Can the ISL80030AFRZ-T operate at 100% duty cycle?
Yes, the ISL80030AFRZ-T supports true 100% duty cycle operation, allowing VOUT to track VIN down to the minimum input voltage (2.7V). This is enabled by its PMOS high-side switch and verified in the "100% Duty Cycle" section (page 17) and Electrical Specifications (page 8, PHASE Maximum Duty Cycle = 100%).
What is the recommended output capacitor for the ISL80030AFRZ-T?
The datasheet specifies 22µF ceramic output capacitance (C1) as standard for all VOUT values from 0.8V to 3.3V (Table 2, page 3). This value ensures stability with the internal compensation network and supports the 2MHz switching frequency. Low-ESR X5R/X7R dielectrics are recommended to maintain ripple below 20mVPP at full load.
