Product details
Overview
ISL91133IIO-EVZ from Renesas Electronics is an evaluation board for the ISL91133IIOZ high-efficiency 2.3A boost regulator with input-to-output bypass functionality. It supports fixed 3.7V/3.77V output variants, operates from 2.35V–5.4V input, delivers up to 2.3A at 3.3V output, features 2.5MHz switching frequency, and enables forced or auto bypass via a 38mΩ internal MOSFET - designed for smartphone power management and RF PA supply.
For engineers reviewing the ISL91133IIO-EVZ datasheet, ISL91133IIO-EVZ pinout, ISL91133IIO-EVZ application, or ISL91133IIO-EVZ equivalent, this page provides verified board-level specifications, supported IC functionality (ISL91133IIOZ), test configuration details, thermal performance data, and design guidance for USB OTG power source and 4G RF amplifier applications.
Technical Context
The ISL91133IIO-EVZ implements a complete reference design for the ISL91133IIOZ boost regulator, configured with 0.47µH inductor (TDK TFM201610A), dual 22µF X5R input/output capacitors, and optimized PCB layout per Renesas' W4x4.16E WLCSP package requirements. It validates both PWM and PFM operation modes, soft-start sequencing (ILIN1 = 1300mA, ILIN2 = 2400mA), and bypass transition timing (TBYP_BST/TBST_BYP).
This board demonstrates real-world behavior of key ISL91133IIOZ features: 38mΩ bypass FET (Q3) enabling <100mV dropout, 96% peak efficiency at 1A load (VIN=3.3V, VOUT=3.3V), thermal warning at +120°C, and PG open-drain power-good signaling synchronized to output regulation stability.

FAQ
What is the primary function of the ISL91133IIO-EVZ evaluation board?
The ISL91133IIO-EVZ evaluation board is a fully assembled and tested platform for validating the ISL91133IIOZ 2.3A boost regulator with bypass capability. It enables engineers to characterize efficiency, transient response, bypass transition timing, and thermal behavior under real load conditions using the exact 16-ball WLCSP package and recommended external components specified in the ISL91133IIOZ datasheet.
Which output voltage variants does the ISL91133IIO-EVZ support?
The ISL91133IIO-EVZ is configured for the ISL91133IIOZ variant, which provides dual fixed output voltages of 3.7V (LO) and 3.77V (HI), selectable via the VSEL pin. This matches the ordering information table in the FN8680 datasheet and is confirmed by the board's default jumper and schematic configuration.
Does the ISL91133IIO-EVZ include thermal measurement capability?
Yes - the ISL91133IIO-EVZ board incorporates thermal monitoring points aligned with the ISL91133IIOZ die location, supporting direct IR thermography or thermocouple measurement. Its layout follows Renesas' W4x4.16E package thermal guidelines, and the board validates the IC's thermal warning (+120°C) and shutdown (+150°C) thresholds as specified in the Electrical Specifications table on page 4 of FN8680 Rev 1.00.
How is bypass mode activated on the ISL91133IIO-EVZ?
Bypass mode on the ISL91133IIO-EVZ is activated either automatically (BYPS pin pulled HIGH) when VIN exceeds VOUT by >1.5% for 5µs with no switching activity, or forcibly (BYPS pin pulled LOW) regardless of input-output differential. The board includes test points and jumpers to toggle BYPS and monitor LX/VOUT waveforms during mode transitions, as shown in Figures 20–21 of the datasheet.
What external components are pre-installed on the ISL91133IIO-EVZ board?
The ISL91133IIO-EVZ board includes a TDK TFM201610A 0.47µH shielded inductor, dual 22µF X5R ceramic capacitors (input and output), and all required resistors and jumpers per the Figure 1 typical application circuit in FN8680. These match the manufacturer-recommended values and vendor selections listed in Tables 1 and 2 of the datasheet.
