Product details
Overview
The ISL97656IRTZEVALZ from Renesas Electronics is an evaluation board designed exclusively for the ISL97656 high-frequency, high-efficiency step-up DC/DC voltage regulator. It supports input voltages from 2.3V to 5.5V, delivers up to 2A output current, and enables switching frequency selection between 620kHz and 1.2MHz - optimized for portable equipment and TFT-LCD display power supplies.
For engineers reviewing the ISL97656IRTZEVALZ datasheet, ISL97656IRTZEVALZ pinout, ISL97656IRTZEVALZ application, or ISL97656IRTZEVALZ equivalent, this board provides a fully assembled, RoHS-compliant platform with proven layout, dip-switch configurable frequency and enable control, and validated thermal pad grounding per the ISL97656 TDFN-10 package requirements.
Technical Context
The ISL97656IRTZEVALZ implements the ISL97656 IC in a fixed-output boost configuration using a 10µH power inductor (SLF12575T-100M5R4-PF), 22µF input/output ceramic capacitors, and a FYD0504SATM Schottky diode. It replicates production-level PCB stackup and thermal management, including signal-ground-connected thermal pad routing at pins 4 and 5 of the ISL97656.
Frequency selection is achieved via S1 dip switch: closing pins 1–4 sets FREQ to VIN for 1.25MHz operation; opening them pulls FREQ to GND through R4 for 620kHz. EN control is similarly implemented via pins 2–3 of S1, tying EN to VIN (active) or GND (disabled) through R3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Board Type | Evaluation board for ISL97656 step-up regulator - not a standalone IC or discrete component. |
| Input Voltage Range | 2.3V to 5.5V - matches ISL97656 operating range; requires external DC supply with ≤4A current limit. |
| Output Current Capability | Up to 2A typical (1.2MHz, 10µH); limited by MOSFET current sense threshold (guaranteed 3.8A, nominal 4A). |
| Switching Frequency Options | Selectable 620kHz or 1.25MHz via onboard DIP switch - directly controls ISL97656 FREQ pin biasing. |
| Output Voltage | Configured for 12V output (per VOUT header and Table 1 test conditions); FB resistor divider (R1=88.7k, R2=10k) sets regulation point. |
| RoHS Compliance | Pb-free assembly - verified per AN1473 Rev 1.00; suitable for commercial-grade electronics manufacturing. |

FAQ
What is the ISL97656IRTZEVALZ used for?
The ISL97656IRTZEVALZ is an evaluation board used to characterize and validate the performance of the ISL97656 step-up voltage regulator under real-world conditions. It enables engineers to verify efficiency, transient response, thermal behavior, and frequency-dependent output capability without designing a custom PCB - supporting rapid prototyping for TFT-LCD and portable power systems.
Does the ISL97656IRTZEVALZ include the ISL97656 IC?
Yes, the ISL97656IRTZEVALZ includes one ISL97656 IC mounted in a 10-lead µTDFN package (TDFN-10 footprint). The IC is pre-soldered and fully integrated into the board's boost converter circuit, including feedback resistors, compensation network, and thermal pad grounding as specified in the ISL97656 datasheet.
How do I configure the switching frequency on the ISL97656IRTZEVALZ?
Use the onboard S1 DIP switch: close pins 1 and 4 to connect the ISL97656 FREQ pin to VIN for 1.25MHz operation; open pins 1 and 4 to pull FREQ to GND via R4 for 620kHz. This configuration directly mirrors the ISL97656's internal oscillator control and is verified in AN1473 Rev 1.00.
What input and output connections does the ISL97656IRTZEVALZ require?
The ISL97656IRTZEVALZ requires three external connections: VIN (2.3V–5.5V DC, ≤4A limit) to the VIN header, GNDIN to the GNDIN header, and VOUT load to the VOUT header. Output ground must be connected to OUT_GND. All headers use Powerpost terminals for secure probing and load attachment.
Is the ISL97656IRTZEVALZ RoHS compliant?
Yes, the ISL97656IRTZEVALZ is Pb-free and RoHS compliant, as confirmed in AN1473 Rev 1.00 and the Bill of Materials. All passives, ICs, and connectors meet EU RoHS Directive requirements, making it suitable for commercial electronics production environments where environmental compliance is mandatory.
