Product details
Overview
ISL80030AFRZ-T7A from Renesas Electronics (formerly Intersil) is a 2MHz PWM-mode synchronous buck converter delivering up to 3A continuous output current from a 2.7V–5.5V input. It integrates low-rDS(ON) PMOS/NMOS power switches, eliminates boot capacitor requirement, supports 100% duty cycle operation, and targets point-of-load regulation in space-constrained industrial and telecom systems.
For engineers reviewing the ISL80030AFRZ-T7A datasheet, ISL80030AFRZ-T7A pinout, ISL80030AFRZ-T7A application, or ISL80030AFRZ-T7A equivalent, key selection criteria include its fixed 2MHz switching frequency, 0.6V feedback reference, 10µA typical quiescent current in active PWM mode, integrated soft-start/soft-stop, and thermal/overcurrent protection with fast transient response.
Technical Context
The ISL80030AFRZ-T7A uses peak current-mode control with slope compensation (900mV/Ts) and a transconductance error amplifier (40µA/V) internally compensated by a 27pF/200kΩ network. Its 0.6V reference voltage sets output via external resistor divider, and maximum EAMP output is clamped at 1.6V for stability.
It implements fast pulse-by-pulse current limiting using a 300mV/A current-sense gain and triggers overcurrent shutdown when P-FET current exceeds 4.5A (typ). The device enters forced shutdown at 150°C with 25°C hysteresis and discharges output through a 100Ω internal resistor during disable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | 2MHz - enables use of sub-2.2µH inductors and reduces output ripple without increasing filter size. |
| Input Voltage Range | 2.7V to 5.5V - compatible with single-cell Li-ion, USB 5V, and 3.3V/5V system rails. |
| Max Output Current | 3A continuous - sufficient for FPGA core, DSP, or ASIC point-of-load supplies. |
| Feedback Reference | 0.600V ±6mV - allows precise output setting down to 0.8V with standard resistor tolerances. |
| Quiescent Current | 10µA to 22µA - minimizes standby power loss in always-on subsystems. |
| Efficiency Peak | Up to 95% - achieved at mid-load with 3.3VIN/1.8VOUT, reducing thermal load in sealed enclosures. |
| Duty Cycle Range | 0% to 100% - supports ultra-low dropout operation, e.g., 3.3VIN → 3.3VOUT. |
Pinout & Package
ISL80030AFRZ-T7A is housed in an 8-lead 2mm × 2mm DFN package with exposed thermal pad (EPAD), optimized for high-density PCB layouts and thermal dissipation (θJA = 70°C/W, θJC = 7°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN (Pins 1, 2) | Input power supply rail | Supplies both power stage and internal LDO; requires ≥10µF ceramic decoupling close to pins. |
| EN (Pin 3) | Enable control input | Active-high logic: >1.4V enables regulator; <0.4V disables with 100Ω output discharge path. |
| PG (Pin 4) | Power-good open-drain output | Asserts low during soft-start or if VOUT falls below 85% or rises above 117% of nominal. |
| FB (Pin 5) | Feedback node | Connects to resistor divider; internal 0.6V reference enables accurate output voltage programming. |
| PGND (Pins 6, 7) | Power and analog ground | Must be connected directly to PCB ground plane; multiple vias to EPAD improve thermal and noise performance. |
| PHASE (Pin 8) | Switching node | Drives external inductor; discharged via 100Ω resistor during shutdown to prevent output voltage hold-up. |
| EPAD | Exposed thermal pad | Electrically tied to PGND; mandatory connection for thermal integrity and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| PMOS high-side switch | Eliminates boot capacitor requirement, simplifying layout and reducing BOM count by one component. |
| Integrated soft-start/soft-stop | 1ms typical ramp time prevents inrush current and output overshoot during power-up/down sequences. |
| 100% duty cycle capability | Enables dropout operation - critical for battery-powered systems where input may dip near output voltage. |
| Overtemperature protection | Shuts down at 150°C with 25°C hysteresis, preventing thermal runaway in enclosed or high-ambient environments. |
| Negative current protection | Disables both FETs if inductor valley current reaches –2A for two cycles, avoiding reverse conduction losses. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS54302DDCR | 3A, 2.5–6VIN, 2MHz, 0.6VREF, but uses NMOS high-side requiring boot capacitor. | Larger board footprint due to external boot circuit; less suitable for ultra-thin designs. | Choose when higher input voltage range (up to 6V) is required and boot capacitor placement is acceptable. |
| MP2315GJ-Z | 3A, 4.5–28VIN, 500kHz, 0.8VREF, no 100% duty cycle, lower switching frequency. | Requires larger inductor/capacitor; not viable for Li-ion direct input or space-constrained layouts. | Prefer for wide-input industrial supplies where efficiency at light load matters more than size or dropout. |
Compared with TPS54302DDCR and MP2315GJ-Z, the ISL80030AFRZ-T7A uniquely combines 2MHz operation, PMOS high-side architecture, 100% duty cycle, and 0.6V reference in a 2×2mm DFN - making it optimal for miniaturized, battery-sensitive, and low-dropout POL designs.

FAQ
What is the switching frequency of the ISL80030AFRZ-T7A?
The ISL80030AFRZ-T7A operates at a fixed 2MHz switching frequency, as confirmed in Table 1 of the FN8766 datasheet. This enables use of small inductors (1.0–3.3µH) and ceramic capacitors while maintaining excellent transient response and minimizing EMI filtering requirements in dense PCB layouts.
Does the ISL80030AFRZ-T7A require an external boot capacitor?
No, the ISL80030AFRZ-T7A does not require an external boot capacitor because it integrates a PMOS high-side MOSFET. This architecture eliminates the need for charge-pump or bootstrap circuitry, reducing component count and simplifying layout - a key differentiator versus NMOS-based buck controllers.
What protection features are built into the ISL80030AFRZ-T7A?
The ISL80030AFRZ-T7A includes overcurrent protection (trip at 4.5A typ), short-circuit protection (VFB < 0.3V triggers frequency reduction), overtemperature shutdown (150°C with 25°C hysteresis), negative current protection (–2A valley limit), and input UVLO (2.7V rising threshold). All are fully integrated and require no external components.
Can the ISL80030AFRZ-T7A operate with 100% duty cycle?
Yes, the ISL80030AFRZ-T7A supports true 100% duty cycle operation, allowing it to maintain regulation even when input voltage equals or slightly drops below the desired output voltage - essential for Li-ion battery applications where VIN can fall to 3.0V while powering a 3.3V rail.
What is the feedback reference voltage of the ISL80030AFRZ-T7A?
The ISL80030AFRZ-T7A has a precision internal feedback reference voltage of 0.600V ±6mV (over –40°C to +125°C), enabling accurate output voltage programming from 0.8V upward using standard resistor dividers - critical for low-voltage digital core supplies.
