Analog Devices Inc. ADP2114-2PH-EVALZ

Overview

ADP2114-2PH-EVALZ from Analog Devices is an evaluation board designed to demonstrate and validate the ADP2114 dual synchronous step-down DC-DC regulator in single interleaved 4 A output configuration. It delivers 1.2 V at up to 4 A with 1.2 MHz switching frequency, forced PWM mode, and operates from 2.75 V to 5.5 V input. The board supports performance evaluation, load transient testing, efficiency measurement, and configuration modification for point-of-load power design validation.

For engineers reviewing the ADP2114-2PH-EVALZ datasheet, ADP2114-2PH-EVALZ pinout, ADP2114-2PH-EVALZ application, or ADP2114-2PH-EVALZ equivalent, this board enables rapid characterization of interleaved dual-phase operation, soft-start behavior, PGOOD monitoring, SYNC/CLKOUT interface, and thermal performance under real-world load conditions - critical for FPGA, ASIC, and processor core rail development.

Technical Context

The ADP2114-2PH-EVALZ implements the ADP2114 in a preconfigured single-output, dual-phase interleaved topology where both channels operate at 180° phase shift, sharing feedback (FB1/FB2 shorted), compensation (COMP1/COMP2 shorted), enable (EN1/EN2 tied), and power-good (PGOOD1/PGOOD2 tied) signals. Output is combined via solder bridge CB3 to deliver 1.2 V at 4 A with reduced ripple and improved transient response.

It uses 1.0 µH inductors (L1/L2), 47 µF ×2 output capacitors (C14/C16), 10 nF soft-start capacitors (C7/C9), and R19 = 27 kΩ to set f_SW = 1.2 MHz. Forced PWM mode is enabled by R14 = 4.7 kΩ, eliminating pulse-skipping discontinuities for consistent EMI and regulation under light loads.

FAQ

What is the primary function of the ADP2114-2PH-EVALZ?

The ADP2114-2PH-EVALZ is an evaluation board that demonstrates the ADP2114's dual-phase interleaved 4 A output capability. It is preconfigured to deliver 1.2 V at up to 4 A with 1.2 MHz switching and forced PWM mode. Engineers use it to validate voltage regulation accuracy, load/line transient response, efficiency curves, thermal behavior, and system-level integration before final PCB layout - not for production deployment.

How is the ADP2114-2PH-EVALZ configured differently from the ADP2114-EVALZ?

The ADP2114-2PH-EVALZ is configured for single interleaved 1.2 V @ 4 A output using forced PWM mode and 1.2 MHz switching (R19 = 27 kΩ), while the ADP2114-EVALZ provides dual independent outputs (3.3 V @ 2 A and 1.8 V @ 2 A) at 600 kHz with pulse-skip enabled. Key hardware differences include shorted CB1–CB5 links, 1.0 µH inductors (vs. 4.7 µH/2.2 µH), and R14 = 4.7 kΩ (vs. 0 Ω) on the ADP2114-2PH-EVALZ.

Can the ADP2114-2PH-EVALZ be reconfigured for dual independent outputs?

Yes - the ADP2114-2PH-EVALZ can be modified for dual independent outputs by removing solder bridges CB1, CB2, CB3, CB4, and CB5; replacing R14 with 0 Ω for pulse-skip mode; updating R19 to 8.2 kΩ for 600 kHz; and adjusting R15/R16/R17/R18 per Table 3 to set desired VOUT1 and VOUT2 voltages. Component values for inductors, output capacitors, and compensation networks must also be recalculated per the ADP2114 datasheet.

What are the key test points and connectors on the ADP2114-2PH-EVALZ?

The ADP2114-2PH-EVALZ features J1 (VIN+), J2 (GND), J3 (+VOUT1), J4 (GND1), J5 (GND2), J6 (+VOUT2), T1–T7 terminals for VIN, GND, VOUT1, GND1, VOUT2, GND2, and combined VOUT/GND, plus TP1 (SYNC/CLKOUT), PGOOD1, PGOOD2, SS1, SS2, EN1, EN2, and SWx switch-node test points. These allow direct probing of input/output voltages, enable signals, power-good status, soft-start timing, and switching waveforms without soldering.

Does the ADP2114-2PH-EVALZ support external clock synchronization?

Yes - the ADP2114-2PH-EVALZ supports external synchronization via TP1 (SYNC/CLKOUT). To use it, place the HEADER3 SCFG shunt in the "in" position (shorted to GND) to configure the pin as SYNC input, then apply an external clock signal with logic-high ≥2.0 V, logic-low ≤0.8 V, pulse width >100 ns, and frequency f_SYNC = 2 × f_SW = 2.4 MHz (±20% tolerance). This enables precise timing alignment with system clocks or other converters.
