Product details

Overview

The ISL97516IUZEVALZ from Renesas Electronics is an evaluation board designed specifically for the ISL97516 high-frequency, high-efficiency step-up DC-DC voltage regulator IC. It supports input voltages from 2.3V to 5.5V, delivers up to 12V output, achieves over 90% efficiency, and features user-selectable switching frequencies of 620kHz or 1.2MHz via on-board DIP switch S1 - enabling rapid validation in portable power applications.

For engineers reviewing the ISL97516IUZEVALZ datasheet, ISL97516IUZEVALZ pinout, ISL97516IUZEVALZ application, or ISL97516IUZEVALZ equivalent, this board provides a fully assembled, RoHS-compliant platform with proven layout, integrated current-limiting protection, and direct access to key control pins (EN, FSEL, FB, COMP) for real-world performance characterization under variable load and input conditions.

Technical Context

The ISL97516IUZEVALZ implements the ISL97516's fixed-frequency current-mode PWM architecture in a functional hardware environment. It replicates the IC's internal 8-pin µSOP-8 pinout and includes all critical external components: 10µH power inductor (Sumida CDRH8D43-100NC), SS25 Schottky diode, 22µF input/output ceramic capacitors (Murata GRM31CR61C226KE15L), and precision feedback resistors (85.2kΩ/10kΩ) setting a nominal 12V output.

Switching frequency selection is implemented via physical DIP switch S1: closing pins 1–4 applies VIN to FSEL for 1.2MHz operation; opening them pulls FSEL to GND through R4 for 620kHz. Enable control uses pins 2–3 of S1 to tie EN to VIN (active) or GND (disabled), matching the ISL97516's logic-level enable interface and internal 1.2V threshold.

Key Specifications

Parameter	Value and Actual Design Meaning
Board Type	Evaluation board for ISL97516 step-up regulator - not a standalone IC or discrete component.
Input Voltage Range	2.3V to 5.5V - matches ISL97516's operational range; validated with 2.5V, 3.3V, and 5V sources per test data.
Output Voltage	12V nominal - set by R1/R2 feedback divider; stable across loads up to I_OMAX = 1150mA @ 3.3V_IN/12V_OUT.
Switching Frequency	User-selectable 620kHz or 1.2MHz - directly controls trade-off between efficiency, EMI, and inductor size in target designs.
Peak Efficiency	>90% - achieved at mid-load conditions; verified with electronic load and oscilloscope per AN1472 test methodology.
Max Output Current	1150mA typical @ 3.3V_IN/12V_OUT; limited by ISL97516's internal MOSFET current limit (guaranteed ≥1.7A).

FAQ

What is the ISL97516IUZEVALZ used for?

The ISL97516IUZEVALZ is an evaluation board for the ISL97516 step-up regulator IC. It enables engineers to validate performance - including efficiency, transient response, and thermal behavior - under real operating conditions before integrating the ISL97516 into final PCB designs. The ISL97516IUZEVALZ is not a production component but a development tool with pre-populated, optimized circuitry.

Does the ISL97516IUZEVALZ support adjustable output voltage?

No, the ISL97516IUZEVALZ is configured for a fixed 12V output using a precision 85.2kΩ/10kΩ resistor divider network per the ISL97516's feedback specification. To evaluate other output voltages, users must replace R1 and/or R2 with values calculated from V_OUT = 1.25V × (1 + R1/R2); the ISL97516IUZEVALZ board provides solder pads for such modifications.

How do I configure the switching frequency on the ISL97516IUZEVALZ?

Use DIP switch S1: close pins 1 and 4 to connect FSEL to VIN for 1.2MHz operation; open pins 1 and 4 to pull FSEL to GND via R4 for 620kHz. This matches the ISL97516's datasheet-specified FSEL pin functionality and allows direct correlation between board behavior and IC electrical characteristics.

Can the ISL97516IUZEVALZ be used with input voltages below 2.3V?

No - the ISL97516IUZEVALZ is designed strictly for the ISL97516's specified 2.3V–5.5V input range. Operation below 2.3V may cause startup failure, regulation loss, or undefined behavior because the ISL97516's internal bias circuitry and gate drive are not guaranteed outside that range. The ISL97516IUZEVALZ reflects these limits without modification.

Is the ISL97516IUZEVALZ RoHS compliant?

Yes, the ISL97516IUZEVALZ is Pb-free and RoHS compliant, as confirmed in the AN1472 User's Manual and Bill of Materials. All passive components (capacitors, resistors, inductor), the ISL97516 IC, SS25 diode, and DIP switch meet EU RoHS Directive requirements, making it suitable for environmentally regulated commercial and industrial deployments.
