Product details
Overview
ADP2114ACPZ-R7 from Analog Devices is a configurable dual-channel synchronous step-down DC-DC regulator supporting 2 A/2 A, 3 A/1 A, or combined 4 A output. It operates from 2.75 V to 5.5 V input, delivers ±1.5% reference accuracy, and supports selectable switching frequencies up to 2 MHz. It powers point-of-load rails in telecom infrastructure and high-performance signal chain systems.
For engineers reviewing the ADP2114ACPZ-R7 datasheet, ADP2114ACPZ-R7 pinout, ADP2114ACPZ-R7 application, or ADP2114ACPZ-R7 equivalent, key selection factors include dual-phase interleaving for reduced input ripple, independent enable/PGOOD per channel, programmable soft start, and thermal/overcurrent protection with hiccup mode recovery.
Technical Context
The ADP2114ACPZ-R7 implements current-mode control with dual PWM channels operating in 180° phase shift to minimize input capacitor RMS current. Its integrated P-channel high-side and N-channel low-side MOSFETs feature RDS(ON) of 52 mΩ / 27 mΩ (at 5 V) and support minimum on/off times down to 107 ns / 192 ns.
It provides bidirectional SYNC/CLKOUT functionality-configurable as external clock input (200 kHz–2 MHz) or 90° out-of-phase clock output at 2× fSW. Operation modes include pulse-skip for light-load efficiency or forced PWM for EMI-sensitive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.75 V to 5.5 V - supports single-supply operation from common intermediate bus voltages (3.3 V, 5 V). |
| Output Configuration | Dual 2 A / 2 A, 3 A / 1 A, or single 4 A interleaved - enables flexible rail partitioning or high-current consolidation without external phase management. |
| Switching Frequency | 300 kHz / 600 kHz / 1.2 MHz (selectable) or syncable 200 kHz–2 MHz - allows optimization of size vs. efficiency and system noise coordination. |
| Reference Accuracy | ±1.5% over −40°C to +125°C - ensures tight output regulation across industrial temperature range without external trimming. |
| Protection Features | Hiccup-mode overcurrent, thermal shutdown (150°C), UVLO (2.75 V rising), and independent PGOOD - enables robust fault handling in unattended systems. |
| Package | 32-lead 5 mm × 5 mm LFCSP with exposed thermal pad - provides low thermal resistance (θJA = 34°C/W) for high-power density layouts. |
Pinout & Package
ADP2114ACPZ-R7 uses a 32-lead, 5 mm × 5 mm lead-frame chip-scale package (LFCSP) with an exposed thermal pad connected to analog ground. Pin numbering follows standard top-view orientation with Pin 1 at top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Analog/Digital Ground Reference | Must connect to signal/analog ground plane before power ground - critical for noise immunity and error amplifier stability. |
| COMP1 / COMP2 (Pins 2, 7) | Error Amplifier Output | Connect RC compensation network to GND; tie together for multiphase configuration to synchronize loop dynamics. |
| FREQ (Pin 3) | Switching Frequency Select | Resistor-to-GND sets nominal fSW: 300 kHz (GND), 600 kHz (8.2 kΩ), 1.2 MHz (27 kΩ) - determines inductor size and EMI profile. |
| SYNC/CLKOUT (Pin 5) | Bidirectional Clock Interface | Configured via SCFG: as input for system-wide clock sync, or as 90°-phase-shifted 2×fSW output for multi-phase stacking. |
| VIN1–VIN6 (Pins 25–27, 14–16) | High-Side MOSFET Power Inputs | Three dedicated VIN pins per channel reduce IR drop and improve current sharing - requires local 10 Ω isolation from VDD. |
| PGND1–PGND4 (Pins 22–20, 21) | Power Ground Returns | Four separate PGND pins per channel minimize ground bounce and enable clean return path separation for each switch node. |
| SW1–SW4 (Pins 24, 23, 18, 17) | Switch Node Outputs | Two SW pairs per channel - tie SW1/SW2 and SW3/SW4 respectively to reduce layout parasitics and EMI radiation. |
Key Features
| Feature | Design Value |
|---|---|
| Configurable Dual-Phase Architecture | Supports independent 2 A/2 A outputs or interleaved 4 A single output - reduces input capacitance requirement by ~50% vs. single-phase. |
| Optimized Gate Slew Rate | Controlled edge rates minimize high-frequency EMI emissions - enables compliance with Class B conducted emission limits without added filtering. |
| Independent Enable & PGOOD | EN1/EN2 and PGOOD1/PGOOD2 allow sequenced power-up and per-rail fault monitoring - essential for FPGA, ASIC, and multi-voltage SoC supplies. |
| Externally Programmable Soft Start | SS1/SS2 accept capacitor-based timing (e.g., 10 nF = 1 ms) - prevents inrush current and controls voltage ramp rate during startup. |
| Thermal & Overcurrent Protection | Hiccup-mode current limiting (8 cycles to trip) and 150°C thermal shutdown with 25°C hysteresis - protects against sustained overload without latch-off. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel synchronous buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS54227PWPR (Texas Instruments) | Fixed 2 A dual output only; no 4 A interleaved mode; 4.5–18 V input; no CLKOUT capability. | Limited to mid-range input buses; lacks synchronization flexibility for multi-phase expansion. | Choose when higher input voltage (>5.5 V) and lower cost outweigh configurability and EMI control needs. |
| MP2491DS-LF-Z (Monolithic Power Systems) | 2 A/2 A fixed dual output; 4.5–18 V input; no soft-start programming; no PGOOD per channel. | Requires external sequencing IC for complex power-up sequences; less suitable for safety-critical monitoring. | Prefer for cost-sensitive consumer applications where independent rail monitoring is not required. |

FAQ
What is the maximum supported switching frequency for ADP2114ACPZ-R7?
The ADP2114ACPZ-R7 supports internal oscillator frequencies of 300 kHz, 600 kHz, or 1.2 MHz, and can be synchronized to an external clock up to 2 MHz. When configured as a clock output, CLKOUT delivers 2×fSW - up to 2.4 MHz in 1.2 MHz mode. This enables high-frequency operation for compact magnetics while maintaining stability across temperature and input voltage.
Can ADP2114ACPZ-R7 operate in forced PWM mode across all load conditions?
Yes, ADP2114ACPZ-R7 supports forced PWM operation via the OPCFG pin configuration, eliminating pulse-skipping discontinuities. This ensures constant switching frequency and predictable EMI spectrum - critical for noise-sensitive applications like ADC reference supplies or RF bias rails where variable-frequency artifacts must be avoided.
How does the ADP2114ACPZ-R7 handle overcurrent events?
The ADP2114ACPZ-R7 implements hiccup-mode current limiting: after eight consecutive current-limit cycles, it shuts down and auto-restarts after thermal recovery. Peak current limits are programmable per channel (e.g., 2.4–4.0 A for Ch1, 1.2–2.6 A for Ch2) using OPCFG resistor values - enabling tailored protection for asymmetric load requirements.
What is the purpose of the six VIN pins on ADP2114ACPZ-R7?
The ADP2114ACPZ-R7 features three VIN pins per channel (VIN1–VIN3 for Ch1; VIN4–VIN6 for Ch2) to minimize PCB trace resistance and inductance feeding the high-side MOSFETs. This reduces voltage drop and improves current sharing under high transient loads - especially beneficial in high-current, low-output-voltage configurations where IR losses dominate efficiency.
Does ADP2114ACPZ-R7 support output voltage adjustment below 0.8 V?
Yes, ADP2114ACPZ-R7 supports adjustable output down to 0.6 V using external resistor dividers on FB1/FB2. The internal reference is 0.6 V ±1.5%, enabling precise low-voltage rails for advanced process nodes (e.g., 0.6 V core for 7 nm ASICs). Fixed outputs (0.8 V–3.3 V) are selected via V1SET/V2SET resistor-to-GND connections.
