Analog Devices Inc./Maxim Integrated MAX17501BTEVKIT#

Overview

MAX17501BTEVKIT# from Maxim Integrated is an evaluation kit for the MAX17501B 60V, 500mA synchronous step-down DC-DC converter with fixed 5V output, TDFN-10 (3mm × 2mm) package, ±1.7% output voltage accuracy over –40°C to +125°C, and peak efficiency >90% at full load - used to validate power delivery in industrial control and telecom point-of-load designs.

For engineers reviewing the MAX17501BTEVKIT# datasheet, MAX17501BTEVKIT# pinout, MAX17501BTEVKIT# application, or MAX17501BTEVKIT# equivalent, this kit enables rapid characterization of input transient response, PFM vs. forced-PWM operation, soft-start timing, RESET assertion behavior, and thermal performance under real-world 4.5V–60V input conditions with pre-layout-optimized PCB and documented test points.

Technical Context

The MAX17501BTEVKIT# implements the MAX17501B IC in a fully assembled, tested, and calibrated reference design featuring a 10-pin TDFN footprint, integrated 5V LDO (VCC), EN/UVLO threshold programmable via external resistor divider, open-drain RESET with 1024-cycle delay, and adjustable soft-start via SS capacitor.

It supports both PFM (for high light-load efficiency) and forced-PWM (for EMI-sensitive applications) modes, includes hiccup-mode overcurrent protection triggered at 780mA runaway current limit, and delivers stable 5V ±1.7% regulation across –40°C to +125°C ambient with all-ceramic output capacitance and no external compensation required.

FAQ

What is the primary purpose of the MAX17501BTEVKIT#?

The MAX17501BTEVKIT# is an evaluation kit for the MAX17501B 5V fixed-output synchronous step-down DC-DC converter. It provides a ready-to-use hardware platform with pre-validated layout, test points, and documentation to accelerate design-in, performance verification, and compliance testing of the MAX17501B in real-world 4.5V–60V input applications.

Does the MAX17501BTEVKIT# support both PFM and forced-PWM modes?

Yes, the MAX17501BTEVKIT# supports both operating modes as implemented by the onboard MAX17501B IC. PFM mode improves light-load efficiency by skipping pulses, while forced-PWM maintains constant 600kHz switching for predictable EMI - selectable via configuration jumpers or external control signals per the MAX17501B datasheet.

Can the MAX17501BTEVKIT# be used to evaluate thermal performance?

Yes, the MAX17501BTEVKIT# includes a thermally optimized 4-layer PCB with exposed pad soldered to internal ground planes, enabling accurate junction temperature measurement and thermal derating analysis. The MAX17501B's thermal shutdown (165°C) and 10°C hysteresis are fully observable during sustained 500mA load testing.

What output voltage does the MAX17501BTEVKIT# deliver, and how accurate is it?

The MAX17501BTEVKIT# delivers a fixed 5.00V output with ±1.7% regulation accuracy over –40°C to +125°C ambient temperature, matching the MAX17501B's specified VOUT tolerance. Measured output remains within 4.922V–5.225V across full load and temperature range per electrical characteristics table.

Is the MAX17501BTEVKIT# compatible with other MAX17501 variants like MAX17501A or MAX17501F?

No - the MAX17501BTEVKIT# is specifically configured for the MAX17501B variant (5V fixed output, 600kHz, PFM mode). While the PCB footprint matches all MAX17501 TDFN-10 versions, component values (feedback network, soft-start capacitor, etc.) are optimized for MAX17501B; substituting other variants requires revalidation of loop stability and timing.
