Analog Devices Inc./Maxim Integrated MAX17291EVK#WLP

Overview

MAX17291EVK#WLP from Maxim Integrated is a fully assembled and tested evaluation kit designed to validate the MAX17291ANT+ low-quiescent-current boost DC-DC converter in 6-bump WLP (0.4mm pitch). It supports 1.8V–5.5V input, delivers up to 310mA at 12V output (default configuration), and features TrueShutdown™, short-circuit protection, and resistor-configurable output (5.5V–20V).

For engineers reviewing the MAX17291EVK#WLP datasheet, MAX17291EVK#WLP pinout, MAX17291EVK#WLP application, or MAX17291EVK#WLP equivalent, this EV kit enables rapid functional validation of the MAX17291's high-efficiency step-up operation, compact layout implementation, and enable-control behavior under real-world load and input conditions.

Technical Context

The MAX17291EVK#WLP implements the MAX17291ANT+ IC on a proven 2-layer, 1.5oz copper PCB with optimized component placement for minimal EMI and thermal rise. Input voltage is applied via banana jacks (IN/GND), output is accessed at OUT/GND terminals, and enable control is managed through jumper JU1 (pins 1–2 = enabled, 2–3 = disabled).

Output voltage is set by resistive divider R1/R2 (3.48MΩ/402kΩ), yielding 12V per design; optional resistor changes allow reconfiguration across 5.5V–20V. The board includes test points (EN, TP2–TP4, LX), a 10µH shielded inductor (L1), 10µF/4.7µF ceramic input/output capacitors, and a 150µF aluminum electrolytic capacitor (C6) for bulk output filtering.

FAQ

What is the default output voltage of the MAX17291EVK#WLP, and how is it set?

The MAX17291EVK#WLP is factory-configured for 12V output using R1 = 3.48MΩ and R2 = 402kΩ in the feedback divider network. This ratio sets V_OUT = 1.215V × (1 + R1/R2) ≈ 12V. Users may replace R1/R2 to achieve other outputs between 5.5V and 20V, as specified in the MAX17291ANT+ datasheet. The MAX17291EVK#WLP schematic and BOM confirm these values are populated and tested.

Does the MAX17291EVK#WLP include the MAX17291 IC, and what package is used?

Yes, the MAX17291EVK#WLP ships with the MAX17291ANT+ pre-installed. This variant uses a 6-bump wafer-level package (WLP) with 0.4mm pitch and outline code N60E1+1. The BOM explicitly lists U1 as "MAX17291ANT+" and identifies its package as "WLP6", confirming full compatibility with the target IC's mechanical and electrical interface.

How do I enable or disable the MAX17291 on the MAX17291EVK#WLP?

Enable/disable control is implemented via jumper JU1: shunt pins 1–2 to assert EN = IN (enabled); shunt pins 2–3 to pull EN = GND (disabled). Table 1 in the user guide confirms this mapping, and the board silkscreen labels JU1 positions accordingly. When disabled, TrueShutdown™ ensures no forward or reverse current flows between IN and OUT - a key behavior verified during MAX17291EVK#WLP functional testing.

What input and output connections does the MAX17291EVK#WLP use?

The MAX17291EVK#WLP uses 4mm banana jacks for IN, OUT, PGND, and PGND2 - enabling safe, low-inductance connection to lab power supplies and electronic loads. Input accepts 1.8V–5.5V DC; output delivers the configured voltage (e.g., 12V) with up to 310mA continuous current. Ground connections are separated (PGND for power path, GND for signal) to minimize noise coupling - a layout choice documented in the MAX17291EVK#WLP PCB files.

Is the MAX17291EVK#WLP RoHS compliant and fully assembled?

Yes, the MAX17291EVK#WLP is RoHS compliant (denoted by # in ordering info) and shipped fully assembled and tested. All components - including the MAX17291ANT+, L1 (10µH shielded inductor), C1/C8 (10µF ceramics), C2/C5 (4.7µF ceramics), C6 (150µF aluminum electrolytic), and R1/R2 - are soldered and verified. No assembly or configuration is required before first power-up, per the Quick Start procedure in the reference documentation.
