Analog Devices Inc./Maxim Integrated MAX15462BEVKIT#

Overview

MAX15462BEVKIT# from Analog Devices is an evaluation kit for the MAX15462B 42V, 300mA synchronous step-down DC-DC converter with fixed 5V output, peak-current-mode control, PFM/PWM mode selection, internal MOSFETs, and integrated soft-start and open-drain RESET monitoring. It supports industrial sensor and 4–20mA loop applications requiring compact, high-efficiency point-of-load regulation.

For engineers reviewing the MAX15462BEVKIT# datasheet, MAX15462BEVKIT# pinout, MAX15462BEVKIT# application, or MAX15462BEVKIT# equivalent, this kit enables rapid validation of the MAX15462B's 4.5V–42V input range, 5V/300mA output, -40°C to +125°C operation, MODE-selectable efficiency modes, and RESET-based output supervision in real PCB layouts.

Technical Context

The MAX15462BEVKIT# implements the MAX15462B IC in a fully assembled, tested 8-pin TDFN (2mm × 2mm) reference design with external 33µH inductor, 10µF ceramic output capacitor, and 1µF input/VCC bypass capacitors. It replicates the typical operating circuit shown in Figure 5 of the datasheet for 5V output under PFM and PWM modes.

It exposes all critical signals-VIN, EN/UVLO, MODE, FB/VOUT, RESET, LX, VCC, and GND-for probing, signal injection, and load transient testing. The board supports configurable EN/UVLO threshold via resistor divider and includes test points for VOUT, RESET, and LX waveforms per Analog Devices' recommended layout guidelines.

FAQ

What is the primary function of the MAX15462BEVKIT#?

The MAX15462BEVKIT# is an evaluation kit that provides a fully populated, tested PCB implementation of the MAX15462B 5V-output synchronous buck converter. It enables engineers to validate electrical performance-including efficiency, transient response, RESET behavior, and MODE-switching-under real-world conditions before integrating the MAX15462B into their final design.

Does the MAX15462BEVKIT# support adjustable output voltages?

No. The MAX15462BEVKIT# is configured specifically for the MAX15462B variant, which delivers a fixed 5V output. To evaluate adjustable outputs, the MAX15462CEVKIT# (for MAX15462C) must be used, as it includes an external resistor divider on the FB/VOUT pin to set VOUT between 0.9V and 0.89×VIN.

Can the MAX15462BEVKIT# operate across the full -40°C to +125°C temperature range?

Yes. The MAX15462BEVKIT# uses the MAX15462B IC rated for -40°C to +125°C ambient operation, and its PCB layout follows Analog Devices' thermal guidelines-including optimized copper pour and minimal thermal resistance paths-to ensure reliable validation across the full industrial temperature range.

How is the MODE pin configured on the MAX15462BEVKIT#?

The MODE pin on the MAX15462BEVKIT# is left unconnected by default to enable PFM operation at light loads. A solder jumper or external pull-down resistor can ground MODE to force constant-frequency PWM mode-matching the configuration options documented in the MAX15462 datasheet Section "Mode Selection (MODE)".

What components are included on the MAX15462BEVKIT# board?

The MAX15462BEVKIT# includes the MAX15462B IC in 8-pin TDFN, 33µH shielded inductor, 10µF X7R ceramic output capacitor, two 1µF X7R input/VCC bypass capacitors, EN/UVLO resistor divider network, RESET pull-up resistor, test points for VIN, VOUT, RESET, and LX, and a compact 2-layer PCB compliant with Analog Devices' layout recommendations.
