Product details
Overview
ISL80015AFRZ-T7A from Renesas (formerly Intersil) is a monolithic synchronous buck DC/DC converter delivering up to 1.5A 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 in an 8-pin 2mm×2mm TDFN package. It supports 100% duty cycle operation and features internal soft-start, power-good signaling, and overcurrent/thermal protection for point-of-load regulation in space-constrained systems.
For engineers reviewing the ISL80015AFRZ-T7A datasheet, ISL80015AFRZ-T7A pinout, ISL80015AFRZ-T7A application, or ISL80015AFRZ-T7A equivalent, key selection criteria include its 2MHz fixed-frequency PWM control, -40°C to +125°C operating junction temperature, 0.6V ±1% feedback voltage accuracy, absence of boot capacitor requirement due to integrated PMOS high-side switch, and thermal pad–enabled thermal performance in the 2mm×2mm footprint.
Technical Context
The ISL80015AFRZ-T7A implements peak current-mode PWM control with slope compensation (900mV/Ts) and a transconductance error amplifier (40µA/V) internally compensated via 27pF/200kΩ network. Its 2MHz oscillator enables fast transient response and permits use of sub-3.3µH inductors while maintaining stability across 0.6V–5.5V output range.
Protection architecture includes cycle-by-cycle overcurrent detection (2.1–2.9A trip threshold), short-circuit response via VFB monitoring (<0.3V), negative current shutdown (-1.5A valley for two cycles), thermal shutdown at +150°C with +25°C hysteresis, and VIN undervoltage lockout (2.2–2.7V rising threshold).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 2.7V to 5.5V - supports single-cell Li-ion, USB, and industrial 3.3V/5V rails without external LDO pre-regulation. |
| IOUT Max | 1.5A continuous - sufficient for FPGA I/O banks, microcontroller cores, and sensor signal chains requiring stable low-noise POL. |
| fSW | 2MHz nominal - enables compact 1.0–2.2µH inductor selection and reduces output ripple without increasing EMI filtering complexity. |
| VFB Accuracy | 0.589V to 0.606V (–40°C to +125°C) - ensures ±1.8% output voltage tolerance over full temperature range without external trimming. |
| Thermal Shutdown | +150°C with +25°C hysteresis - provides robust fault recovery in sealed enclosures or high-ambient industrial environments. |
| Quiescent Current | 10–22mA at 2MHz no load - balances light-load efficiency against control-loop responsiveness for dynamic workloads. |
| Package | 8-pin 2mm×2mm TDFN with exposed thermal pad - achieves <71°C/W θJA and supports >1.5A continuous operation at +85°C ambient with proper PCB copper area. |
Pinout & Package
The ISL80015AFRZ-T7A uses an 8-pin 2mm×2mm TDFN package with exposed thermal pad (EPAD) connected to PGND. The EPAD must be soldered to a dedicated PGND plane using ≥4 vias for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Input power supply rail | Supplies both power stage and internal bias regulator; requires ≥10µF ceramic decoupling placed adjacent to pin. |
| EN | Enable logic input | Active-high enable with 1.4V threshold; pulls PHASE to GND via 100Ω resistor during disable for controlled output discharge. |
| SGND | Signal ground reference | Must be tied directly to EPAD to minimize noise coupling into feedback and control circuitry. |
| PG | Power-good open-drain output | Asserts low during soft-start and when VFB deviates >15% from 0.6V; includes 5MΩ internal pull-up for direct MCU monitoring. |
| FB | Feedback node for output voltage sensing | Connects to resistor divider from VOUT; monitors regulation status for PG and UV/OV protection functions. |
| NC | No-connect terminal | Internally unconnected; must be tied to EPAD per layout guidelines to maintain thermal and EMI performance. |
| PGND | Power and analog ground return | Primary ground path for high-current switching loop; requires low-inductance connection to board GND plane. |
| PHASE | Switching node between MOSFETs | Drives external output inductor; discharged via 100Ω resistor during shutdown to prevent output voltage holdup. |
Key Features
| Feature | Design Value |
|---|---|
| PMOS high-side switch | Eliminates boot capacitor requirement, reducing BOM count and PCB area while enabling 100% duty cycle operation at 1MHz (not applicable at 2MHz). |
| Integrated slope compensation | 900mV/Ts compensation ensures stable current-mode control across all input/output combinations without external components. |
| Internal soft-start | Fixed 1ms ramp time prevents inrush current and output overshoot during power-up, compatible with sequenced supply systems. |
| Negative current protection | Detects –1.5A valley current for two consecutive cycles to prevent reverse inductor current damage during light-load discontinuous conduction mode. |
| Output discharge on shutdown | 100Ω internal switch between PHASE and PGND actively discharges output capacitor, ensuring safe reset in multi-rail systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62130ARGTR | 1.2A max output, 2.5V–6V input, 3MHz switching, 0.6V FB, 12-pin 2mm×3mm WSON | Limited to lower current; higher input voltage ceiling suits 5V rail inputs but lacks 2.7V start-up capability. | Select when 3MHz operation and wider VIN range outweigh 0.3A current reduction and larger package. |
| RT6220AGQW | 1.5A max output, 2.5V–5.5V input, 2MHz switching, 0.6V FB, 8-pin 2mm×2mm QFN | Identical current and frequency specs; differs in EN threshold (1.25V vs 1.4V) and thermal shutdown setpoint (+160°C vs +150°C). | Choose for marginally higher thermal trip point and slightly lower enable threshold in noise-prone environments. |
Compared with TPS62130ARGTR and RT6220AGQW, the ISL80015AFRZ-T7A offers superior low-VIN capability (2.7V start-up), tighter FB accuracy over temperature (±1.8% vs ±2.5%), and optimized 2mm×2mm layout for ultra-dense PCBs-making it preferred for battery-powered and thermally constrained designs where 1.5A output must be sustained down to minimum system voltage.

FAQ
What is the maximum output current and operating temperature range for the ISL80015AFRZ-T7A?
The ISL80015AFRZ-T7A delivers up to 1.5A continuous output current and operates across a junction temperature range of –40°C to +125°C. Its thermal shutdown activates at +150°C with +25°C hysteresis, and full-rated output is maintained at ambient temperatures up to +85°C when the EPAD is properly connected to PGND with ≥4 thermal vias. Derating curves in the datasheet confirm 1.5A capability at +85°C with 5V input and 2MHz switching.
Does the ISL80015AFRZ-T7A require an external boot capacitor?
No, the ISL80015AFRZ-T7A does not require an external boot capacitor because it integrates a PMOS high-side MOSFET. This architecture eliminates the need for charge-pump circuitry or external capacitors typically required by NMOS-based synchronous buck converters. The absence of a boot capacitor reduces component count, saves PCB area, and simplifies layout-confirmed in the datasheet's "Features" section and functional block diagram.
What is the feedback reference voltage and its accuracy over temperature for the ISL80015AFRZ-T7A?
The ISL80015AFRZ-T7A has a nominal feedback reference voltage of 0.600V, with guaranteed accuracy of 0.589V to 0.606V across the full operating junction temperature range of –40°C to +125°C. This ±1.8% tolerance ensures precise output voltage regulation without external calibration, supporting stable 1.2V, 1.8V, or 3.3V generation using standard 1% resistors in the feedback divider network.
How does the ISL80015AFRZ-T7A handle overcurrent and short-circuit conditions?
The ISL80015AFRZ-T7A employs dual protection mechanisms: cycle-by-cycle overcurrent protection trips at 2.1–2.9A (depending on VIN) by monitoring high-side MOSFET current via a 300mV/A gain current-sense amplifier, while short-circuit protection activates when FB falls below 0.3V, forcing oscillator frequency to 1/3 normal rate. Both protections are detailed in the "Theory of Operation" and "Electrical Specifications" sections of the FN6692 datasheet.
Can the ISL80015AFRZ-T7A operate at 100% duty cycle, and under what conditions?
The ISL80015AFRZ-T7A supports 100% duty cycle operation only at its 1MHz variant (e.g., ISL80015FRZ-T7A); the ISL80015AFRZ-T7A is specified for 2MHz operation and does not support 100% duty cycle. This distinction is explicitly stated in Table 1 ("SUMMARY OF KEY DIFFERENCES") and the "Features" list of the FN6692 datasheet, where "100% duty cycle (1MHz)" is noted separately from the A-suffix 2MHz models.
