Product details
Overview
MAX77348EVKIT# from Analog Devices is an evaluation kit designed to validate the MAX77348A and MAX77348B 3.5 W buck-boost converters in WLP packages. It supports 2.3 V–5.5 V input, delivers adjustable 2.5 V–4.8 V output (default 4.5 V), and enables I²C-based voltage configuration and mode control for portable power management applications.
For engineers reviewing the MAX77348EVKIT# datasheet, MAX77348EVKIT# pinout, MAX77348EVKIT# application, or MAX77348EVKIT# equivalent, this kit provides verified hardware for evaluating buck-boost regulation, active discharge behavior, FPWM/skip-mode operation, and I²C register access under real-world load and thermal conditions.
Technical Context
The MAX77348EVKIT# implements a complete reference design around the MAX77348AEWE+ IC - a 16-bump WLP buck-boost converter with integrated FETs, programmable output voltage via SEL resistor or I²C, and configurable switching modes (FPWM or skip). It includes onboard sense points, test points for EN/SDA/SCL/INS/OUTS, and jumper-configurable enable logic.
Hardware features include a 2.2 µH shielded inductor, 22 µF input/output ceramic capacitors, 1 µF bypass cap, and dedicated probe sockets for HVLX/LVLX/OUT1 nodes. The kit integrates the MAXUSB_INTERFACE# module for Windows GUI–driven I²C communication, with strict 1.8 V VIO enforcement to prevent IC damage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Evaluated IC | MAX77348AEWE+, WLP16 package - factory-default device preinstalled on board |
| Input Voltage Range | 2.3 V to 5.5 V - supports single-cell Li-ion, USB PD, and wide-input portable sources |
| Output Voltage Range | 2.5 V to 4.8 V in 50 mV steps - software-adjustable via GUI or hardware-selectable via R3 |
| Max Output Power | 3.5 W at 1 A - validated with 2.2 µH inductor and 22 µF output capacitance |
| UVLO Thresholds | Rising: 2.19 V, Falling: 2.10 V - ensures stable startup/shutdown across battery discharge curves |
| Peak Efficiency | 94.0% at 3.6 VIN/3.3 VOUT/300 mA - measured with default component selection and layout |
| Active Discharge | Engaged when EN = 0 - discharges output capacitor rapidly to prevent residual voltage hold-up |

FAQ
What does the MAX77348EVKIT# evaluate?
The MAX77348EVKIT# evaluates the MAX77348A and MAX77348B buck-boost converters, specifically the MAX77348AEWE+ variant preinstalled on the board. It validates full functionality including I²C register access, output voltage adjustment, FPWM/skip-mode selection, active discharge, and efficiency measurement across input and load ranges.
Does the MAX77348EVKIT# include the MAXUSB_INTERFACE# module?
Yes, the MAX77348EVKIT# includes the MAXUSB_INTERFACE# module (part number MAXUSB_INTERFACE#) as standard equipment. This interface enables Windows-based GUI communication with the MAX77348AEWE+ IC over I²C using a USB Type-A to Micro-USB cable, with onboard 1.8 V LDO powering the VIO rail.
What is the default output voltage of the MAX77348EVKIT#?
The MAX77348EVKIT# has a factory-default output voltage of 4.5 V, set by the onboard SEL resistor R3. This value can be reconfigured in real time via the GUI software or permanently modified by changing R3 per Table 2 in the EV kit documentation.
Can the MAX77348EVKIT# operate without the MAXUSB_INTERFACE#?
Yes, the MAX77348EVKIT# supports standalone operation without the MAXUSB_INTERFACE#. Jumper J2 must be removed to isolate the VL rail, and an external 1.8 V IO supply must be applied to the VIO pin. SDA and SCL lines remain accessible via test points SDA and SCL for custom I²C host connection.
What are the critical test points on the MAX77348EVKIT#?
The MAX77348EVKIT# provides dedicated test points for INS/GND1S (input sensing), OUTS/GNDS2 (output sensing), EN, SDA, SCL, and INT. It also includes precision probe sockets for HVLX, LVLX, and OUT1 to minimize noise during switching waveform, ripple, and transient response measurements.
