Analog Devices Inc./Maxim Integrated MAX17552AEVKIT#

Overview

MAX17552AEVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit designed to demonstrate the performance of the MAX17552A 60V, 100mA synchronous step-down DC-DC converter in a 10-pin TDFN package. It delivers a regulated 5V output across 6V–60V input, achieves 93% peak efficiency at 220kHz switching frequency, and draws only 26µA no-load supply current-ideal for industrial power supply validation and ultra-low-quiescent design verification.

For engineers reviewing the MAX17552AEVKIT# datasheet, MAX17552AEVKIT# pinout, MAX17552AEVKIT# application, or MAX17552AEVKIT# equivalent, this EV kit enables rapid characterization of input UVLO programming, MODE-selectable PWM/PFM operation, open-drain RESET monitoring, soft-start timing adjustment, and external clock synchronization-all with validated PCB layout and production-grade component selection.

Technical Context

The MAX17552AEVKIT# implements the MAX17552A IC in a fixed 5V output configuration with programmable EN/UVLO via resistor-divider (R1/R2), selectable forced-PWM or PFM mode via jumper JU3, and configurable soft-start using capacitor C4. It includes dedicated PCB pads for RT/SYNC, MODE, SS, EN/UVLO, FB, LX, RESET, VIN, VOUT, and GND-enabling full functional validation of the underlying controller's protection and control features.

Performance is characterized across 6V–60V input and 1mA–100mA load, with documented line/load regulation (±0.02V), Bode plot stability (55.24° phase margin), transient response (200µs recovery under 50mA→100mA step), and overload protection behavior. The board integrates a 22µF/100V electrolytic capacitor (C1) to dampen hot-plug oscillations from long input cables.

FAQ

What is the primary function of the MAX17552AEVKIT#?

The MAX17552AEVKIT# is a fully assembled evaluation kit that demonstrates the operation and performance of the MAX17552A synchronous step-down DC-DC converter. It provides a ready-to-use platform for validating input UVLO programming, MODE-selectable PWM/PFM operation, RESET signaling, soft-start timing, and external clock synchronization-without requiring custom PCB development. Engineers use the MAX17552AEVKIT# to verify real-world behavior before integrating the MAX17552A into final systems.

Does the MAX17552AEVKIT# support adjustable output voltage?

No-the MAX17552AEVKIT# is configured for a fixed 5V output using the internal feedback divider of the MAX17552AATB+. Output voltage is not user-adjustable on this board; it is optimized to validate the IC's performance specifically in 5V applications. For variable-output evaluation, a different kit or custom design using the MAX17552A's FB pin would be required. The MAX17552AEVKIT# does not include external resistors to modify the feedback network.

How is undervoltage lockout (UVLO) programmed on the MAX17552AEVKIT#?

UVLO is programmed on the MAX17552AEVKIT# using the onboard resistor divider formed by R1 (3.01MΩ) and R2 (787kΩ), connected to the EN/UVLO pin via jumpers JU1 and JU2. With default shunt positions (JU1=1-2, JU2=1-2), the threshold is set to ~6V turn-on. Engineers can replace R1/R2 to adjust the UVLO threshold per the MAX17552A datasheet equations-enabling validation of brown-out protection for specific input rail requirements using the MAX17552AEVKIT#.

Can the MAX17552AEVKIT# be synchronized to an external clock?

Yes-the MAX17552AEVKIT# includes an RT/SYNC PCB pad that accepts an AC-coupled external clock signal, allowing synchronization of the MAX17552A's 220kHz switching frequency to a system master clock. This feature is critical for noise-sensitive applications like imaging or data acquisition where switching frequency alignment reduces beat frequencies and EMI. The MAX17552AEVKIT# provides direct access to the RT/SYNC pin without modification.

What protection features are demonstrated by the MAX17552AEVKIT#?

The MAX17552AEVKIT# demonstrates cycle-by-cycle overcurrent protection, thermal shutdown, undervoltage lockout, and open-drain RESET assertion (active-low when output drops below 92% of nominal). It also includes R7 and C5 to protect the VOUT pin during short-circuit events-validating safe operation under fault conditions. These protections are inherent to the MAX17552A and fully exercised on the MAX17552AEVKIT# board during standard test procedures.
