Analog Devices Inc./Maxim Integrated MAX16962REVKIT#

Overview

The MAX16962REVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit designed to characterize the MAX16962R 3.3V/4A synchronous step-down DC-DC converter operating at 2.2MHz, with integrated high-side and low-side MOSFETs in a 16-pin TQFN-EP package, used for automotive and industrial power supply validation.

For engineers reviewing the MAX16962REVKIT# datasheet, MAX16962REVKIT# pinout, MAX16962REVKIT# application, or MAX16962REVKIT# equivalent, key selection considerations include input voltage range (3.5V–5.5V), fixed 3.3V output, forced-PWM/skip-mode configurability, SYNC input support (1.7–2.5MHz), and PG1 power-good monitoring capability.

Technical Context

The MAX16962REVKIT# implements a complete, layout-optimized buck converter reference design centered on the MAX16962R IC, which integrates 40mΩ high-side and 20mΩ low-side MOSFETs and operates with internal 2.2MHz switching frequency. It supports external synchronization and configurable operation modes via jumper JU2.

Hardware features include shunt-controlled enable (JU1), dual test points for PG1 and SYNC signals, banana jacks for VSUP/PGND/VOUT, and pre-populated feedback resistors (R6 = 30.1kΩ, R7 = 95.3kΩ) setting VOUT to 3.3V. Input capacitors (C1–C4), output inductor (L1 = 1µH), and compensation network (C7 = 100pF, C8 = 33pF) are selected per MAX16962R's recommended design guidelines.

FAQ

What is the primary function of the MAX16962REVKIT#?

The MAX16962REVKIT# is an evaluation kit that enables functional and performance validation of the MAX16962R synchronous step-down converter. It provides a ready-to-use 3.3V/4A power stage with proven PCB layout, jumpers for mode selection (PWM/skip), enable control, and test points for PG1 and SYNC signals - all pre-assembled and factory-tested for immediate lab use.

Does the MAX16962REVKIT# support output voltage adjustment?

Yes, the MAX16962REVKIT# can be reconfigured for output voltages from 0.8V to 3.6V by replacing feedback resistors R6 and R7. The default 3.3V setting uses R6 = 30.1kΩ and R7 = 95.3kΩ. Compensation capacitors C7 and C8 must also be updated per the MAX16962R datasheet equations to maintain loop stability after reconfiguration.

How is switching mode controlled on the MAX16962REVKIT#?

Switching mode on the MAX16962REVKIT# is controlled via jumper JU2: installed shunt selects forced-PWM mode (fixed 2.2MHz frequency), while removal enables skip mode (variable frequency, lower quiescent current at light loads). The PWM test point allows direct probing of the internal PWM logic signal for timing analysis.

What input power requirements does the MAX16962REVKIT# have?

The MAX16962REVKIT# requires a single DC input of 3.5V–5.5V at up to 4A for full 4A output operation. While the underlying MAX16962R IC supports 2.7V–5.5V, the EV kit's input filtering and layout are optimized for the 3.5V–5.5V range. Banana jacks (VSUP/PGND) provide secure connections for bench supplies and electronic loads.

Can the MAX16962REVKIT# be synchronized to an external clock?

Yes, the MAX16962REVKIT# supports external synchronization via the SYNC test point, accepting digital square-wave clocks from 1.7MHz to 2.5MHz. The signal must meet logic thresholds (0–0.4V low, 1.8V–PSUP high), and synchronization occurs on the rising edge. This feature enables EMI reduction in noise-sensitive systems using the MAX16962R.
