Product details
Overview
MAX38650AEVK#WLP from Maxim Integrated is a fully assembled and tested evaluation kit designed to validate the MAX38650A ultra-low quiescent current (390nA) step-down DC-DC converter in a 6-pin WLP package (1.58mm × 0.89mm, 0.4mm pitch). It supports 1.8V–5.5V input, delivers up to 100mA output, and enables resistor-configurable output voltages from 1.2V to 3.3V - ideal for battery-powered IoT sensors and wearable medical monitors.
For engineers reviewing the MAX38650AEVK#WLP datasheet, MAX38650AEVK#WLP pinout, MAX38650AEVK#WLP application, or MAX38650AEVK#WLP equivalent, this kit provides immediate hardware validation of the MAX38650A's nano-power buck operation, 100% duty-cycle capability, and compact WLP integration in space-constrained embedded systems.
Technical Context
The MAX38650AEVK#WLP implements a complete reference design for the MAX38650A IC, including all critical external components: input/output capacitors (10µF, 22µF, 100µF), 2.2µH power inductor, precision feedback resistors (383kΩ, 634kΩ, 768kΩ, 56.2kΩ), and dual jumpers (JU1 for EN control, JU2 for RSEL configuration). It uses a proven 2-layer, 1oz copper PCB layout optimized for low-noise, high-efficiency nano-power conversion.
Hardware-level configurability is provided via shunt jumpers: JU1 selects between onboard enable (default), external TTL control, or disable; JU2 sets output voltage to 1.2V, 1.5V, 1.8V, 2.5V (open), or 3.3V - directly mapping to the MAX38650A's RSEL pin functionality without soldering or component changes.

FAQ
What does the MAX38650AEVK#WLP evaluate?
The MAX38650AEVK#WLP evaluates the MAX38650AANT+ IC - a 390nA quiescent current, 1.8V–5.5V input, 100mA nano-power buck converter in a 1.58mm × 0.89mm WLP6 package. It includes all necessary passive components, jumpers for EN and RSEL control, and terminal posts for quick bench testing without additional assembly.
How do I configure the output voltage on the MAX38650AEVK#WLP?
Use jumper JU2 to select the output voltage: position 1–2 = 1.2V, 1–3 = 1.5V, 1–4 = 1.8V, open = 2.5V, and 1–5 = 3.3V. This directly configures the RSEL pin of the onboard MAX38650AANT+, as specified in the MAX38650A datasheet - no resistor changes or soldering required.
Can the MAX38650AEVK#WLP be used with an external enable signal?
Yes. Jumper JU1 supports three modes: default (1–2) enables the MAX38650AANT+ onboard; position 1–3 connects EXT_EN to an external TTL source; position 1–4 disables the IC. The EXT_EN pin accepts 0V–5.5V logic levels and is electrically isolated from the main power path per the MAX38650A's enable architecture.
What is the maximum load current supported by the MAX38650AEVK#WLP?
The MAX38650AEVK#WLP delivers up to 100mA continuous output current across its full input (1.8V–5.5V) and output (1.2V–3.3V) ranges, as validated by Maxim's thermal and efficiency characterization. Performance remains stable under light-load conditions due to the MAX38650AANT+'s 390nA quiescent current and pulse-skipping mode.
Does the MAX38650AEVK#WLP include the MAX38650A IC?
Yes. The MAX38650AEVK#WLP ships with the MAX38650AANT+ pre-installed - a production-grade version of the MAX38650A in a 6-pin WLP package (package code N60R1+1, outline 21-100464). No additional IC mounting or rework is needed to begin evaluation.
