Product details
Overview
ISL91107IIN-EVZ from Renesas Electronics is an evaluation board for the ISL91107IINZ fixed 3.3V buck-boost regulator IC, designed to demonstrate high-efficiency power conversion in space-constrained portable applications. It supports input voltages from 1.8V to 5.5V, delivers up to 2A output current at 3.3V, and features a 2.5MHz switching frequency with 45µA quiescent current - enabling compact, low-noise power solutions for smartphones and wireless communication devices.
For engineers reviewing the ISL91107IIN-EVZ datasheet, ISL91107IIN-EVZ pinout, ISL91107IIN-EVZ application, or ISL91107IIN-EVZ equivalent, this board provides validated reference design, thermal performance data, load transient response waveforms, and layout guidance for rapid integration of the ISL91107 buck-boost regulator into battery-powered systems with wide-input-voltage requirements.
Technical Context
The ISL91107IIN-EVZ implements a fully synchronous 4-switch buck-boost topology that automatically transitions between buck and boost modes without output disturbance. It uses a single 1µH inductor and integrates P-channel (45mΩ) and N-channel (32mΩ) MOSFETs, supporting both forced PWM and auto PFM operation via the MODE pin.
This evaluation platform validates key system-level behaviors: soft-start ramp control (2–3ms), VOUT soft-discharge (35Ω internal resistor), hiccup-mode overcurrent protection, and thermal shutdown at +150°C with +30°C hysteresis - all under real-world conditions including line/load transients and temperature extremes (-40°C to +85°C).

FAQ
What is the primary function of the ISL91107IIN-EVZ?
The ISL91107IIN-EVZ is an evaluation board for the ISL91107IINZ buck-boost regulator IC. It provides a fully assembled, tested reference design to validate performance - including efficiency, transient response, thermal behavior, and layout best practices - before integrating the ISL91107IINZ into end products like smartphones and wireless modems.
Does the ISL91107IIN-EVZ support adjustable output voltage?
No - the ISL91107IIN-EVZ is configured for the fixed 3.3V output version (ISL91107IINZ). It uses no external feedback resistors and ships with R1=187kΩ and R2=60.4kΩ pre-soldered to set 3.3V. For adjustable outputs, the ISL91107IIA-EVZ evaluation board must be used with the ISL91107IIAZ device.
What external components are included on the ISL91107IIN-EVZ board?
The ISL91107IIN-EVZ board includes a 1µH shielded inductor (TOKO DFE322512C), 22µF X5R input capacitor (Murata GRM188R61A226ME15D), two parallel 22µF X5R output capacitors, and a 22pF compensation capacitor. All components match Renesas' recommended BOM for optimal efficiency and stability.
How does the ISL91107IIN-EVZ demonstrate mode transition behavior?
The ISL91107IIN-EVZ enables observation of automatic buck-to-boost transition via oscilloscope measurements at LX1/LX2 and VOUT. When input voltage crosses ~3.3V under load, the board shows seamless mode switching with <50mV output ripple - validating the ISL91107's patented control architecture without external intervention or configuration changes.
Can the ISL91107IIN-EVZ be used for production deployment?
No - the ISL91107IIN-EVZ is strictly an evaluation and development tool. It is not qualified for production use. For volume deployment, designers must implement the ISL91107IINZ IC on their own PCB using the layout guidelines, thermal management techniques, and component selection criteria validated by the ISL91107IIN-EVZ reference design.
