Analog Devices Inc./Maxim Integrated MAX77752EVKIT#

Overview

MAX77752EVKIT# from Maxim Integrated is an evaluation kit for the MAX77752 multichannel power management IC - a highly integrated PMIC featuring three buck regulators (2A/2A/3A), one 0.15A LDO, two dedicated load switch controllers, and an OTP-configurable inrush-current limiter. It supports I²C-based configuration and flexible power sequencing for space-constrained portable systems.

For engineers reviewing the MAX77752EVKIT# datasheet, MAX77752EVKIT# pinout, MAX77752EVKIT# application, or MAX77752EVKIT# equivalent, this kit enables rapid validation of voltage rail sequencing, load switch timing, brownout response, and low-power state transitions in SSDs, handheld devices, drones, and industrial cameras.

Technical Context

The MAX77752EVKIT# implements the full reference design for the MAX77752 PMIC, including all critical support circuitry: input filtering, output LC networks for BUCK1–BUCK3 and LDO, external MOSFETs for load switches, current-sense resistors, thermal monitoring, and I²C pull-up networks. It replicates the 40-pin TQFN (5mm × 5mm) footprint and layout guidelines specified in Maxim's land pattern 90-0016.

It provides access to all 40 pins via 0.1"-spaced headers and test points, supports factory-programmable OTP options via I²C, and enables real-time measurement of PGOOD assertion delays (31.5µs–1.016ms), LP_REQ timing (20ms max), and inrush gate-drive oscillator frequencies (5.625kHz–720kHz) under controlled SYS and VIN conditions.

FAQ

What is the primary function of the MAX77752EVKIT#?

The MAX77752EVKIT# is an evaluation kit designed to accelerate development with the MAX77752 multichannel PMIC. It provides a fully assembled, tested reference platform with all necessary passive components, MOSFETs, and interface circuitry to validate voltage rail generation, sequencing, load switching, and low-power state behavior without custom PCB design.

Does the MAX77752EVKIT# support factory OTP programming?

Yes, the MAX77752EVKIT# supports OTP programming of the MAX77752 via I²C using Maxim's official software tools. Key OTP-configurable features include inrush limiter operation mode, brownout thresholds, reset delay values, power-up/down sequence timing, and gate drive oscillator frequency settings - all accessible through standard I²C commands on the kit.

Can the MAX77752EVKIT# be used to evaluate all three buck regulators simultaneously?

Yes, the MAX77752EVKIT# powers and monitors all three buck regulators (BUCK1, BUCK2, BUCK3) concurrently. Each has dedicated output capacitors, inductors, and test points. Load testing up to 2A (BUCK1/2) and 3A (BUCK3) is supported with appropriate external loads and thermal management per the kit's design guidelines.

What interfaces are accessible on the MAX77752EVKIT#?

The MAX77752EVKIT# provides full access to the MAX77752's I²C interface (SDA/SCL), all GPIOs (LP_REQ, LP_ACK, LP_MODE, WP_L, RESET_L, PGOOD, EREG_EN1/2, EREG_POK, BLD_IO), and all power inputs/outputs (VSYS, VINB1–3, VBUCK1–3, VLDO, INR_OUT). All signals are routed to 0.1"-spaced headers and labeled test points.

Is thermal performance validated on the MAX77752EVKIT#?

Yes, the MAX77752EVKIT# incorporates thermal design best practices per Maxim's layout recommendations, including copper pours, thermal vias, and component placement aligned with the MAX77752's θJA = 28°C/W (4-layer board) spec. The kit enables direct measurement of junction temperature rise and verification of thermal overload shutdown at 165°C with 15°C hysteresis.
