FAQ

What is the purpose of the MAX17502ETEVKIT#?

The MAX17502ETEVKIT# is a fully assembled evaluation kit for the MAX17502E 60V, 1A synchronous step-down DC-DC converter. It provides engineers with a ready-to-use platform to validate electrical performance, thermal behavior, EMI compliance, and layout implementation of the MAX17502E IC in real-world conditions - including load transients, soft-start sequencing, RESET timing, and efficiency vs. load curves.

Does the MAX17502ETEVKIT# support adjustable output voltage?

No. The MAX17502ETEVKIT# is specifically configured for the MAX17502E variant with fixed 3.3V output. It uses the internal feedback divider and does not include external resistors for output adjustment. For adjustable output testing, the MAX17502GTEVKIT# or MAX17502HTEVKIT# must be used - those kits implement the MAX17502G or MAX17502H ICs with external R4/R5 feedback networks.

What input voltage range can be tested with the MAX17502ETEVKIT#?

The MAX17502ETEVKIT# supports input voltages from 4.5V to 60V DC, matching the operational range of the MAX17502E IC. Test data in the user guide includes efficiency, thermal, and transient performance at 12V, 24V, 36V, and 48V inputs - confirming stable regulation and hiccup-mode protection under overvoltage and overload conditions within this range.

How is the RESET signal implemented on the MAX17502ETEVKIT#?

The MAX17502ETEVKIT# implements the open-drain RESET output of the MAX17502E IC with an external 10kΩ pull-up resistor to V_OUT. RESET asserts low when FB drops below 92.5% of 3.3V (≈3.07V) and releases high 1024 switching cycles after FB rises above 95.5% of 3.3V (≈3.15V). This behavior is verified in oscilloscope waveforms included in the MAX17502ETEVKIT# user guide.

Can the MAX17502ETEVKIT# be used for thermal design validation?

Yes. The MAX17502ETEVKIT# includes thermal imaging data and junction-to-ambient thermal resistance (θ_JA = 67.3°C/W) measurements for the 10-pin TDFN package on a multilayer PCB. It validates heatsinking effectiveness via the exposed pad connection to GND and demonstrates safe operation up to 1A load at +70°C ambient - supporting thermal margin analysis for end-equipment designs using the MAX17502E IC.
