Analog Devices Inc./Maxim Integrated MAX17506EVKITBE#

Overview

MAX17506EVKITBE# from Maxim Integrated is a fully assembled and tested evaluation kit designed to validate the MAX17506 synchronous step-down DC-DC converter in 5V/5A high-efficiency power supply applications. It operates from 6.5V–60V input, delivers regulated 5V output at up to 5A, features 450kHz switching frequency, adjustable soft-start, EN/UVLO control via JU1, and MODE selection (PWM/PFM/DCM) via JU2.

For engineers reviewing the MAX17506EVKITBE# datasheet, MAX17506EVKITBE# pinout, MAX17506EVKITBE# application, or MAX17506EVKITBE# equivalent, this kit supports rapid validation of input voltage range, load regulation, EMI compliance (CISPR22 Class B), thermal performance, and synchronization capability with external clock signals - all critical for industrial and automotive power design.

Technical Context

The MAX17506EVKITBE# implements the MAX17506 TQFN-20 EP (5mm × 5mm) IC in a fixed 5V output configuration with integrated high-side and low-side MOSFETs (U1 = MAX17506ATP+), 4.7µH power inductor (L1), and optimized PCB layout for EMI and thermal management. Input filtering includes 4.7µF/100V ceramic capacitors (CIN8/CIN9) and optional 47µF/80V electrolytic (CIN7) for hot-plug suppression.

It provides three configurable operating modes via JU2: PWM (JU2 pins 1–2), PFM (JU2 open), and DCM (JU2 pins 2–3); RESETB monitoring (active-low, open-drain); SYNC capability for external clock synchronization; and EN/UVLO programming through resistor divider (R1/R2) or jumper (JU1). The board complies with CISPR22 Class B conducted and radiated emissions limits.

FAQ

What is the primary function of the MAX17506EVKITBE#?

The MAX17506EVKITBE# is a fully assembled evaluation kit that validates the electrical performance, thermal behavior, and EMI characteristics of the MAX17506 synchronous step-down DC-DC converter. It provides immediate hardware access to key features including adjustable UVLO, soft-start timing, mode selection (PWM/PFM/DCM), RESETB monitoring, and external clock synchronization - all preconfigured for 5V/5A operation.

Does the MAX17506EVKITBE# support input voltages above 48V?

Yes, the MAX17506EVKITBE# supports input voltages from 6.5V to 60V as specified in its design documentation. Components such as CIN8/CIN9 (4.7µF/100V X7R), CIN7 (47µF/80V electrolytic), and the MAX17506ATP+ IC itself are rated for this full range. Operation at 60V requires proper derating of input capacitance ESR and verification of thermal margin under maximum load.

How is output voltage set on the MAX17506EVKITBE#?

The MAX17506EVKITBE# is preset for 5V output using a fixed resistor divider network (R3/R4) connected to the FB pin of the MAX17506ATP+. No user adjustment is required - the feedback network sets VOUT = 5V ±1% across the full 0–5A load range and 6.5–60V input range, as confirmed in the load regulation plots (TOC01, TOC03, TOC06).

Can the MAX17506EVKITBE# be used to evaluate EMI performance?

Yes, the MAX17506EVKITBE# includes designated footprints for an optional conducted EMI filter (L2 + CIN4/CIN9), and its PCB layout is optimized to meet CISPR22 Class B radiated and conducted emissions limits. Measured data (TOC16, TOC17, TOC18) confirms compliance when configured per the default jumper settings and with recommended filter components installed.

What jumper configurations are factory-default on the MAX17506EVKITBE#?

The MAX17506EVKITBE# ships with JU1 shunted across pins 1–2 (enabling the device at VIN ≥6.4V) and JU2 left unshunted (defaulting to PFM mode). These settings are documented in the "DEFAULT JUMPER TABLE" on page 8 of the EV kit documentation and enable out-of-box evaluation of light-load efficiency and basic startup behavior.
