Product details
Overview
ISL91133IIQ-EVZ from Renesas Electronics is an evaluation board designed to accelerate functional validation of the ISL91133 integrated boost-with-bypass switching regulator for single-cell Li-ion/Li-polymer battery systems. It supports 5.0V/5.2V output via jumper-selectable VSET, delivers up to 2.3A at VIN = 2.5V, operates from 2.35V–5.4V input, and features 2.5MHz switching frequency with <110µA quiescent current in Boost mode.
For engineers reviewing the ISL91133IIQ-EVZ datasheet, ISL91133IIQ-EVZ pinout, ISL91133IIQ-EVZ application, or ISL91133IIQ-EVZ equivalent, this board enables rapid assessment of high-efficiency power conversion, auto/forced bypass mode behavior, light-load PFM operation, and transient response under real-world load conditions - critical for portable medical, wearables, and IoT edge devices.
Technical Context
The ISL91133IIQ-EVZ implements a complete reference design for the ISL91133 WLCSP regulator, integrating all necessary passive components (inductor L1 = 0.47µH, input/output capacitors C2/C3/C4 = 22µF each) and configurable jumpers (J3 for EN, J4 for VSET, J5 for BYPS). It operates across –40°C to +85°C ambient temperature and supports both Auto Bypass (VIN > 1.015×VOUT) and Forced Bypass modes.
Input power connects via 6-pin header J1; output loads interface through 6-pin header J2. Test points TP1–TP5 provide direct access to VIN, VOUT, SW, PG, and GND nodes. The board's layout follows Renesas' thermal and EMI best practices: wide copper pours on VIN/VOUT/GND planes, AGND/PGND tied near U1, and short, wide traces between LX and L1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Board Type | Evaluation board for ISL91133 boost-with-bypass regulator - not a standalone IC or discrete component. |
| Output Voltage Options | 5.0V / 5.2V selectable via VSET jumper (J4), enabling compensation for load transient droop. |
| Max Output Current | 2.3A at VIN = 2.5V, VOUT = 3.3V - validated per AN1958 test conditions; performance scales with input voltage and output setting. |
| Input Voltage Range | 2.35V to 5.4V - covers full discharge-to-charge range of single-cell Li-ion (2.7V–4.4V) plus margin. |
| Switching Frequency | 2.5MHz - reduces external inductor and capacitor size; fixed-frequency PWM with PFM at light loads. |
| Quiescent Current | ~110µA in Boost mode, ~95µA in Auto Bypass, ~45µA in Forced Bypass - directly measurable at test points. |
| Ambient Temperature Range | –40°C to +85°C - matches industrial-grade operating envelope of ISL91133 IC. |

FAQ
What is the ISL91133IIQ-EVZ used for?
The ISL91133IIQ-EVZ is an evaluation board for the ISL91133 boost-with-bypass regulator IC. It allows engineers to validate key performance metrics - including efficiency across load ranges, bypass transition behavior, startup waveforms, and transient response - without designing a custom PCB. The board ships with all required passives and configurable jumpers for immediate lab testing.
Does the ISL91133IIQ-EVZ include the ISL91133 IC?
Yes, the ISL91133IIQ-EVZ includes one ISL91133 regulator IC in WLCSP package (U1), mounted and fully populated per Renesas' reference design. The IC is pre-soldered and tested; no additional assembly is required to operate the board.
How do I configure the ISL91133IIQ-EVZ for 5.2V output?
To set 5.2V output on the ISL91133IIQ-EVZ, install a jumper on J4 (VSET header) connecting pin 1 to pin 2 (VSET = HIGH). This selects the higher of the two factory-programmed output voltages (5.0V/5.2V) as specified in the ordering information table of AN1958.
Can the ISL91133IIQ-EVZ operate in Forced Bypass mode?
Yes - the ISL91133IIQ-EVZ supports Forced Bypass mode by installing a jumper on J5 (BYP header) connecting pin 2 to pin 3 (BYP = GND). In this state, the internal 38mΩ bypass switch remains closed regardless of input-output voltage relationship, reducing quiescent current to ~45µA.
What are the key test points on the ISL91133IIQ-EVZ?
The ISL91133IIQ-EVZ provides four labeled test points: TP1 (GND), TP2 (SW node), TP3 (VOUT), and TP4 (PG - Power Good signal). TP5 is reserved for AGND. These allow oscilloscope probing of switching waveforms, output regulation, enable timing, and fault signaling during characterization.
