Product details
Overview
ISL91132IIM-EVZ from Renesas Electronics is an evaluation board for the ISL91132IIMZ high-efficiency 1.8A boost regulator with input-to-output bypass functionality. It supports fixed 3.3V/3.5V output, operates from 2.35V–5.4V input, delivers up to 1.8A at 3.3V, features 2.5MHz switching, and enables forced/auto bypass via a 38mΩ internal MOSFET - used in smartphone power management for RF PA supply and USB OTG.
For engineers reviewing the ISL91132IIM-EVZ datasheet, ISL91132IIM-EVZ pinout, ISL91132IIM-EVZ application, or ISL91132IIM-EVZ equivalent, this page provides verified board-level specifications, layout guidance, supported IC variant details (ISL91132IIMZ), measured efficiency curves, and component selection criteria per AN1942.
Technical Context
The ISL91132IIM-EVZ implements a complete reference design for the ISL91132IIMZ boost regulator, featuring a 0.47µH shielded inductor, dual 22µF X5R ceramic input/output capacitors, and optimized PCB layout per Renesas AN1942. It validates both PWM (2.5MHz valley-current mode) and PFM light-load operation, as well as seamless transition between boost and forced/auto bypass modes.
Board-level validation includes thermal performance under 1.5A load, load transient response (10mA→1500mA→10mA), soft-start timing (600µs), and PG flag assertion accuracy. All measurements align with FN8637 Rev.2.00 electrical specs for the ISL91132IIMZ, including 96% peak efficiency at 1A and 45µA quiescent current in Forced Bypass mode.

FAQ
What is the primary function of the ISL91132IIM-EVZ evaluation board?
The ISL91132IIM-EVZ evaluation board is a fully assembled and tested platform for validating the ISL91132IIMZ 1.8A boost regulator with bypass capability. It enables engineers to measure efficiency, transient response, thermal behavior, and mode transitions (boost ↔ forced/auto bypass) under real-world conditions using the exact component layout and bill-of-materials specified in AN1942. The board directly supports ISL91132IIMZ characterization without custom PCB development.
Which ISL91132 variant does the ISL91132IIM-EVZ evaluate?
The ISL91132IIM-EVZ evaluates the ISL91132IIMZ variant, which provides dual fixed output voltages of 3.3V (LO) and 3.5V (HI), selectable via the VSEL pin. This is confirmed by the Ordering Information table on page 3 of FN8637 Rev.2.00, where ISL91132IIMZ-T is marked "3.3/3.5" and ISL91132IIM-EVZ is explicitly listed as its evaluation board.
Does the ISL91132IIM-EVZ include the ISL91132IIMZ IC pre-soldered?
Yes, the ISL91132IIM-EVZ includes the ISL91132IIMZ IC pre-mounted in its 16-ball WLCSP package (1.78mm × 1.78mm, 0.4mm pitch). The board uses the exact same footprint, thermal pad configuration, and decoupling network specified in the ISL91132IIMZ package drawing W4x4.16E, ensuring direct correlation between evaluation results and production implementation.
What external components are required to operate the ISL91132IIM-EVZ?
No external components are required to operate the ISL91132IIM-EVZ - it ships fully populated with the ISL91132IIMZ IC, 0.47µH shielded inductor (TDK TFM201610A), dual 22µF X5R input/output capacitors, and all necessary resistors and jumpers per Figure 1 of FN8637. Users only need a DC input source (2.35V–5.4V), load, and optional oscilloscope/probe for measurement.
Where can I find the schematic, layout files, and test procedures for the ISL91132IIM-EVZ?
The official schematic, PCB layout (Gerber), BOM, and step-by-step test procedures for the ISL91132IIM-EVZ are published in Application Note AN1942, "ISL91132 Evaluation Board User Guide", available on the Renesas website. This document includes measured waveforms, efficiency plots, thermal images, and instructions for configuring VSEL, BYPS, and EN pins - all specific to the ISL91132IIM-EVZ hardware revision.
