Product details
Overview
ISL91107IRN-EVZ from Renesas (formerly Intersil) is an evaluation board designed specifically for the ISL91107IRTNZ fixed-output 3.3V buck-boost switching regulator. It supports input voltages from 1.8V to 5.5V, delivers up to 2A output current at 3.3V, operates at 2.5MHz switching frequency, and functions across –40°C to +85°C ambient temperature - enabling rapid validation of power architecture in battery-powered portable electronics.
For engineers reviewing the ISL91107IRN-EVZ datasheet, ISL91107IRN-EVZ pinout, ISL91107IRN-EVZ application, or ISL91107IRN-EVZ equivalent, this board provides hands-on access to key regulator behaviors including auto-PFM/forced-PWM mode selection, enable control via jumper, low-ripple regulation near VIN ≈ VOUT, and high-efficiency operation across wide input ranges typical of Li-ion, Li-polymer, and emerging battery chemistries.
Technical Context
The ISL91107IRN-EVZ implements a dedicated hardware platform for the ISL91107IRTNZ IC - a 20-pin 3×4mm TQFN-packaged buck-boost controller with fixed 3.3V output, proprietary four-switch topology, and integrated gate drivers. Its design centers on evaluating dynamic response, efficiency mapping, and thermal performance under real-world load transients and input voltage sag conditions.
Board-level features include dual 6-pin connectors (J1 for PVIN/VIN, J2 for VOUT/load), test points for LX1/LX2/VOUT/EN/MODE, and configurable jumpers (J3 for EN, J4 for MODE) - all supporting direct oscilloscope probing and bench-level characterization without soldering or modification.

FAQ
What is the purpose of the ISL91107IRN-EVZ evaluation board?
The ISL91107IRN-EVZ is a ready-to-use hardware platform for evaluating the ISL91107IRTNZ fixed 3.3V buck-boost regulator. It enables engineers to verify startup behavior, load transient response, efficiency curves, and thermal performance without designing custom PCBs - directly supporting early-stage power architecture validation for battery-powered devices.
Does the ISL91107IRN-EVZ support adjustable output voltage?
No. The ISL91107IRN-EVZ is configured exclusively for the ISL91107IRTNZ IC, which has a factory-trimmed fixed 3.3V output. Unlike the ISL91107IRA-EVZ (which uses the adjustable ISL91107IRTAZ), this board omits the R2 feedback resistor and sets FB internally - ensuring consistent 3.3V regulation without external programming.
How do I enable or disable the regulator on the ISL91107IRN-EVZ?
Enable/disable control is implemented via jumper J3. Shorting pins 1–2 of J3 connects EN to VIN, enabling the ISL91107IRTNZ. Leaving J3 open disables the regulator. This hardware-level control allows safe power sequencing and quick functional verification before connecting loads or instruments.
What are the key differences between ISL91107IRN-EVZ and ISL91107IRA-EVZ?
The ISL91107IRN-EVZ evaluates the fixed 3.3V ISL91107IRTNZ, while the ISL91107IRA-EVZ evaluates the adjustable ISL91107IRTAZ. Key differences include: (1) R2 presence (60.4kΩ on ISL91107IRA-EVZ vs. DNP on ISL91107IRN-EVZ), (2) FB network configuration (external divider vs. internal), and (3) default output setting (programmable 1V–5.2V vs. hardwired 3.3V).
Can the ISL91107IRN-EVZ be used to evaluate other ISL91107 variants?
No. The ISL91107IRN-EVZ is electrically and mechanically optimized for the ISL91107IRTNZ only. Its layout, component values (e.g., inductor, input/output capacitors), and feedback network match the fixed-output variant's specifications. Using it with ISL91107IRTAZ or other variants would require redesign and is not supported per UG066 Rev.2.00.
