Analog Devices Inc./Maxim Integrated MAX17270EVKIT#

Overview

MAX17270EVKIT# from Maxim Integrated is an evaluation kit for the MAX17270 nanoPower triple-output SIMO (Single-Inductor Multiple-Output) buck-boost regulator IC, designed to validate power architecture in ultra-low-power wearable systems. It supports 2.7V–5.5V input, delivers three independently configurable outputs (e.g., 1.2V/80mA, 1.8V/75mA, 3.3V/50mA), and enables rapid prototyping of compact, battery-efficient designs for fitness bands and hearables.

For engineers reviewing the MAX17270EVKIT# datasheet, MAX17270EVKIT# pinout, MAX17270EVKIT# application, or MAX17270EVKIT# equivalent, this kit provides validated reference schematics, layout files, BOM, and firmware tools to accelerate development of space-constrained, multi-rail wearable power systems with <1.3µA operating current and 85% peak efficiency.

Technical Context

The MAX17270EVKIT# implements the full functional interface of the MAX17270 IC, including all 16-pin TQFN signal connections (VPWR, VSUP, OUT1–OUT3, EN1–EN3, RSEL1–RSEL3, LXA/LXB, BST, PGND, GND), enabling direct validation of enable sequencing, output voltage configuration via external resistors, soft-start behavior, and load transient response across all three rails.

It integrates the required 2.2µH power inductor, 10µF input/output capacitors, 100nF BST capacitor, and resistor networks matching Table 1 of the MAX17270 datasheet, supporting immediate evaluation of output accuracy (±2%), line/load regulation (<0.5%), and ultra-low-power mode (ULPM) operation at sub-1µA quiescent current per enabled output.

FAQ

What is the primary function of the MAX17270EVKIT#?

The MAX17270EVKIT# is an evaluation platform for the MAX17270 nanoPower triple-output SIMO buck-boost regulator. It allows engineers to verify performance-including output voltage accuracy, load transient response, efficiency, and ultra-low-power mode-using the exact circuit topology and components specified in the MAX17270 datasheet. The kit directly supports validation of wearable power architectures before custom PCB spin.

Does the MAX17270EVKIT# support the MAX17271 IC?

No, the MAX17270EVKIT# is specifically designed for the MAX17270 IC and does not support the MAX17271. The MAX17271 requires I2C interface, ON/IRQB/RSTB/SDA/SCL pins, and active discharge control - none of which are implemented on the MAX17270EVKIT# board. Its resistor-based RSEL1–RSEL3 configuration and EN1–EN3 enable inputs match only the MAX17270's architecture.

What output voltages and currents are pre-configured on the MAX17270EVKIT#?

The MAX17270EVKIT# is pre-configured per the typical application circuit: OUT1 = 1.2V @ 80mA, OUT2 = 1.8V @ 75mA, and OUT3 = 3.3V @ 50mA. These values correspond to specific RSEL resistor values from Table 1 in the MAX17270 datasheet and are validated for ≤±2% output accuracy and <0.5% load regulation across 0.1mA–100mA loads.

Can the MAX17270EVKIT# be used to evaluate ultra-low-power mode (ULPM)?

Yes, the MAX17270EVKIT# fully supports ULPM evaluation. When output load drops below threshold, the MAX17270 automatically enters ULPM, raising output voltage by +2.5% to minimize undershoot during sudden load steps. The kit's test points and oscilloscope-accessible waveforms (e.g., VOUTx, ILX) allow direct measurement of ULPM entry timing, voltage bias, and recovery behavior as shown in Figures toc07–toc09 of the datasheet.

What documentation and resources ship with the MAX17270EVKIT#?

The MAX17270EVKIT# ships with complete design resources: schematic (PDF), PCB layout (Gerber), BOM (Excel), assembly drawing, and firmware configuration tools. All files align with Maxim Integrated Application Note 1891 and datasheet Rev 5 (9/2019), including verified land patterns for the 16-pin TQFN package (Outline 21-0136) and thermal design guidance (θJA = 48°C/W).
