Analog Devices Inc. ADP5034RE-EVALZ

Overview

ADP5034RE-EVALZ from Analog Devices is a fully assembled, tested evaluation board designed specifically for the ADP5034 dual 3 MHz, 1200 mA buck regulator with two 300 mA LDOs in TSSOP package. It supports standalone characterization of line/load regulation, efficiency, ripple, and transient response using only a single voltage supply, voltmeter, ammeter, and load resistors. The board enables cascaded LDO supply from buck outputs and independent enable/control per channel.

For engineers reviewing the ADP5034RE-EVALZ datasheet, ADP5034RE-EVALZ pinout, ADP5034RE-EVALZ application, or ADP5034RE-EVALZ equivalent, this board provides direct access to all critical test points (VOUT1S–VOUT4S, VIN1, PGND), configurable MODE/EN jumpers (JMODE, JEN1–JEN4), and external resistor divider networks (RT1–RT4, RB1–RB4) for adjustable output voltage validation across buck and LDO rails.

Technical Context

The ADP5034RE-EVALZ implements the full signal and power interface of the ADP5034 TSSOP micro PMU, including dedicated test points for all four regulated outputs (VOUT1–VOUT4), input supplies (VIN1, VIN2, VIN3, VIN4), and ground domains (PGND, AGND, GND). It supports both PSM and forced PWM operation via JMODE jumper selection and allows independent channel enable/disable through shuntable jumpers JEN1–JEN4.

Board-level design includes cascading capability (JV3V1/JV4V2) to feed LDO inputs directly from buck outputs, precision sense terminals (VOUT1S–VOUT4S) for accurate voltage measurement, and factory-populated 0805 resistors (RT1–RT4, RB1–RB4) configured for standard output voltages - all aligned with the ADP5034's 28-lead TSSOP pinout and thermal layout requirements.

FAQ

What is the primary function of the ADP5034RE-EVALZ?

The ADP5034RE-EVALZ is a dedicated evaluation board for the ADP5034 TSSOP micro PMU. It enables complete functional and performance validation - including line/load regulation, efficiency, ripple, and transient response - without requiring custom PCB design. All four regulated outputs (two bucks, two LDOs), enable controls, and MODE configuration are accessible via headers and jumpers on the ADP5034RE-EVALZ.

Does the ADP5034RE-EVALZ support both buck and LDO evaluation simultaneously?

Yes, the ADP5034RE-EVALZ supports concurrent evaluation of all four channels: Buck 1 (VOUT1), Buck 2 (VOUT2), LDO 1 (VOUT3), and LDO 2 (VOUT4). Each channel has independent enable jumpers (JEN1–JEN4), dedicated output sense terminals (VOUT1S–VOUT4S), and configurable input routing (e.g., JVIN3/JVIN4 for LDO supply, JV3V1/JV4V2 for cascading), allowing flexible multi-rail testing on a single ADP5034RE-EVALZ board.

Can the ADP5034RE-EVALZ be used with the ADP5034 in LFCSP package?

No, the ADP5034RE-EVALZ is mechanically and electrically designed exclusively for the ADP5034 in 28-lead TSSOP package. The ADP5034 LFCSP variant uses a different pinout, thermal pad layout, and decoupling scheme; its evaluation is supported by UG-271 and the separate ADP5034LE-EVALZ board. Attempting to mount an LFCSP device on the ADP5034RE-EVALZ will result in misalignment and non-functional connections.

How does the JMODE jumper affect regulator operation on the ADP5034RE-EVALZ?

The JMODE jumper on the ADP5034RE-EVALZ selects between automatic PWM/PSM mode (center-to-bottom shunt, pulling MODE to PGND) and forced PWM mode (center-to-top shunt, pulling MODE to VIN1). This directly controls the switching behavior of both buck regulators: PSM improves light-load efficiency below ~100 mA, while forced PWM ensures constant frequency and predictable transient response across all loads - a key test condition validated on the ADP5034RE-EVALZ.

What components are included in the ADP5034RE-EVALZ bill of materials?

The ADP5034RE-EVALZ includes the ADP5034AREZ (TSSOP-packaged IC), two 1.0 µH shielded inductors (L1/L2), six MLCC input/output capacitors (CIN1–CIN4, COUT1–COUT4), one 0.1 µF bypass capacitor (CIN), and eight precision 0805 resistors (RT1–RT4, RB1–RB4) pre-configured for standard output voltages. All passive components are sourced from Murata, Taiyo Yuden, and Vishay per the official UG-439 BOM - no substitutions or omissions on the shipped ADP5034RE-EVALZ.
