Analog Devices Inc./Maxim Integrated ADPL16000AEVKIT#

Overview

ADPL16000AEVKIT# from Analog Devices is an evaluation kit designed to validate the ADPL16000A high-voltage synchronous step-down DC-DC converter in fixed 3.3V output applications. It supports 5V–48V input, delivers up to 400mA load current, operates at 500kHz fixed switching frequency, and includes programmable undervoltage lockout, open-drain RESET, overcurrent/thermal protection, and CISPR32 Class B EMI compliance.

For engineers reviewing the ADPL16000AEVKIT# datasheet, ADPL16000AEVKIT# pinout (jumper-configurable EN/UVLO, MODE, and feedback terminals), ADPL16000AEVKIT# application (high-voltage industrial power rails, isolated subsystems, and ruggedized embedded supplies), or ADPL16000AEVKIT# equivalent (ADPL16000BEVKIT#, ADPL16000C12EVKIT#), this page provides verified board-level specifications, jumper configuration guidance, and test-ready implementation details.

Technical Context

The ADPL16000AEVKIT# hosts a fully assembled and tested ADPL16000AATA+ IC in a 3.3V fixed-output application circuit, electrically isolated from the ADPL16000B and ADPL16000C sections on the same PCB. It implements resistor-programmable UVLO via jumper JU101 (default open for 5V startup) and mode selection (PFM/PWM) via jumper JU102 (default open for PFM).

Input filtering uses 1µF/100V X7R ceramic (C106) and optional 22µF/100V electrolytic (C103) for hot-plug damping; output employs 22µF/6.3V X7R ceramic (C109). The board's layout follows Analog Devices' proven high-voltage buck design practices, including optimized power loop routing and EMI mitigation structures compliant with CISPR32 Class B conducted/radiated emissions limits.

FAQ

What is the primary function of the ADPL16000AEVKIT#?

The ADPL16000AEVKIT# is a fully assembled evaluation board for the ADPL16000A synchronous step-down DC-DC converter. It enables rapid validation of the ADPL16000A's performance in fixed 3.3V output applications across a 5V–48V input range. The board includes all necessary passive components, jumpers for UVLO and mode configuration, and EMI-optimized layout-allowing engineers to verify efficiency, transient response, thermal behavior, and emissions without custom PCB development. ADPL16000AEVKIT# serves as a reference for system-level integration of the ADPL16000A.

Does the ADPL16000AEVKIT# support adjustable output voltage?

No, the ADPL16000AEVKIT# is configured exclusively for fixed 3.3V output, matching the ADPL16000A's internal feedback network. Unlike the ADPL16000C section on the same multi-converter board, the ADPL16000A section has no user-adjustable output resistors-its feedback divider (R101/R102) is soldered in place for 3.3V regulation. To evaluate adjustable outputs, users must select the ADPL16000C12EVKIT# variant. ADPL16000AEVKIT# does not provide access to modify the output voltage setting.

How do I configure undervoltage lockout on the ADPL16000AEVKIT#?

Undervoltage lockout (UVLO) on the ADPL16000AEVKIT# is controlled via jumper JU101. With JU101 left open (default), the ADPL16000A enables at ~5V input. Installing a shunt across pins 2–3 disables the converter entirely; installing across pins 1–2 connects EN/UVLO directly to VIN, enabling operation across the full input range without threshold programming. Resistor-based UVLO adjustment requires external components and is not implemented on the ADPL16000AEVKIT#-it relies solely on the jumper-selectable modes defined in the ADPL16000A data sheet.

Can the ADPL16000AEVKIT# be used to test PWM vs. PFM operation modes?

Yes, the ADPL16000AEVKIT# supports both PWM and PFM modes via jumper JU102. Leaving JU102 open configures the ADPL16000A for PFM operation at light loads-improving light-load efficiency. Installing a shunt across pins 1–2 forces continuous PWM mode-ensuring constant switching frequency and lower output ripple under all load conditions. This dual-mode capability allows direct comparison of efficiency vs. noise trade-offs during system-level validation. ADPL16000AEVKIT# provides immediate, hardware-level access to this critical operating parameter.

Is the ADPL16000AEVKIT# RoHS compliant?

Yes, the ADPL16000AEVKIT# is RoHS compliant, as indicated by the "#" suffix in its part number per Analog Devices' ordering nomenclature. All components on the board-including the ADPL16000AATA+ IC, Murata and Taiyo Yuden capacitors, Vishay resistors, and Wurth inductors-meet EU RoHS Directive 2011/65/EU requirements. Full compliance documentation, including material declarations and test reports, is available through Analog Devices' official product page and distributor portals for ADPL16000AEVKIT#.
