Product details
Overview
ADPL76030EUFD#TRPBF from Analog Devices is a synchronous 4-switch buck-boost DC/DC controller supporting input voltages from 4 V to 55 V and output voltages from 0 V to 55 V, operating at up to 1.4 MHz with spread spectrum modulation for EMI reduction and ±2% output voltage accuracy. It enables seamless buck, buck-boost, and boost operation in industrial power supplies and telecom voltage regulators.
For engineers reviewing the ADPL76030EUFD#TRPBF datasheet, ADPL76030EUFD#TRPBF pinout, ADPL76030EUFD#TRPBF application, or ADPL76030EUFD#TRPBF equivalent, key selection criteria include its 4-switch single-inductor architecture, peak-buck/peak-boost current-mode control, programmable switching frequency (600 kHz–1.4 MHz), ±3% current-sense accuracy, and integrated INTVCC 5 V LDO regulator.
Technical Context
The ADPL76030EUFD#TRPBF implements a proprietary dual-mode current-mode control scheme-peak-buck in VIN ≫ VOUT and peak-boost in VIN ≪ VOUT-with automatic transition between regions. Its internal oscillator supports fixed-frequency operation or 25% triangle spread spectrum modulation when SYNC/SPRD is tied to INTVCC.
It features independent ISP/ISN and LSP/LSN current-sense inputs for input/output or inductor current monitoring, with 10× gain ISMON output and programmable CTRL-based current limit (5 mV–100 mV full-scale). Fault protection includes FB overvoltage (1.1 V), short-circuit detection, and three configurable response modes (hiccup, latch-off, keep-running) via SS pin resistor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 4 V to 55 V - supports wide-input industrial and telecom rails without pre-regulation. |
| VOUT Range | 0 V to 55 V - enables true buck-boost regulation across input-output crossover. |
| Switching Frequency | 600 kHz to 1.4 MHz - adjustable via RT resistor; synchronizable or spread-spectrum enabled. |
| Output Voltage Accuracy | ±2% - ensures stable CV regulation for sensitive loads like FPGAs or ADCs. |
| Current Sense Accuracy | ±3% - enables precise CC/CV battery charging and load current limiting. |
| INTVCC Regulator | 5.0 V ±1.5%, 145 mA max - powers internal logic and gate drivers without external bias supply. |
| Spread Spectrum | 25% triangle modulation - reduces peak EMI by spreading fundamental and harmonic energy. |
Pinout & Package
ADPL76030EUFD#TRPBF is housed in a 28-lead plastic QFN package (4 mm × 4 mm, 0.5 mm pitch) with exposed thermal pad (Pin 29 = GND) requiring solder connection to PCB ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TG1, TG2 | Buck/Boost top gate drivers | Drive N-channel MOSFET gates with BST-referenced swing; support high-side switching in both power stages. |
| BG1, BG2 | Buck/Boost bottom gate drivers | Drive low-side N-MOSFETs from GND to INTVCC; enable synchronous rectification for efficiency. |
| LSP/LSN | Buck-side inductor current sense | Kelvin-connected inputs for accurate inductor current measurement in buck region. |
| ISP/ISN | Input/output current sense | Dedicated differential inputs for measuring input or output current with ±3% accuracy. |
| FB | Voltage feedback input | Sets regulated output voltage via external resistor divider; triggers fault protection at <0.25 V or >1.1 V. |
| SS | Soft-start and fault mode control | Charged by 12.5 µA current; resistor value selects hiccup/latch-off/keep-running short-circuit response. |
| SYNC/SPRD | Frequency control input | Ground = internal oscillator; INTVCC = 25% spread spectrum; external clock = synchronization. |
| EN/UVLO | Enable and input UVLO | 1.220 V falling threshold enables programmable input undervoltage lockout with hysteresis. |
Key Features
| Feature | Design Value |
|---|---|
| 4-Switch Single-Inductor Architecture | Eliminates need for separate buck and boost converters; reduces BOM count and board space in multi-rail systems. |
| Proprietary Peak-Buck/Peak-Boost Control | Ensures stable current-mode operation across all VIN/VOUT relationships without mode switching artifacts. |
| Integrated INTVCC 5 V LDO | Supplies internal circuitry and gate drivers from VIN; eliminates external bias rail and associated components. |
| Programmable Current Limit via CTRL Pin | Enables precise CC regulation from 5 mV to 100 mV sense threshold using simple resistor divider from VREF. |
| Three Short-Circuit Fault Responses | Selectable via SS pin resistor: hiccup (no resistor), latch-off (499 kΩ), or keep-running (100 kΩ) for system-level fault tolerance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT8708IUF#PBF | Wider VIN range (2.8 V–80 V); no integrated spread spectrum; requires external VREF for current sensing. | Preferred for ultra-low-VIN battery systems; less suitable where EMI certification is critical without added filtering. | Choose LT8708IUF#PBF when input can drop below 4 V or exceed 55 V, and EMI mitigation is handled externally. |
| TPS63070DDAR | Lower VIN max (16 V); integrated power switches (not controller); fixed 2.5 MHz frequency; no ISP/ISN monitoring. | Targeted at compact, low-power consumer devices; lacks precision current monitoring and wide-range flexibility. | Choose TPS63070DDAR only for cost-sensitive, low-current (<2 A), space-constrained designs with narrow input range. |
Compared with LT8708IUF#PBF and TPS63070DDAR, ADPL76030EUFD#TRPBF uniquely combines 4–55 V input, 0–55 V output, programmable spread spectrum, and dual current-sense capability-making it optimal for industrial and telecom systems demanding robustness, accuracy, and EMI control in a single controller.

FAQ
What is the maximum input voltage rating for the ADPL76030EUFD#TRPBF?
The ADPL76030EUFD#TRPBF has an absolute maximum VIN rating of 58 V, with continuous operation specified from 4 V to 55 V. Exceeding 55 V may trigger overvoltage protection or degrade reliability; design margin should maintain VIN ≤ 52 V under transient conditions per datasheet recommendations.
Does the ADPL76030EUFD#TRPBF support both input and output current monitoring?
Yes, the ADPL76030EUFD#TRPBF supports both input and output current monitoring via dedicated ISP/ISN differential inputs. The ISMON pin outputs a voltage equal to ten times V(ISP−ISN) plus 0.25 V offset, enabling ±3% accurate current measurement for either direction depending on external resistor placement.
How is spread spectrum modulation enabled on the ADPL76030EUFD#TRPBF?
Spread spectrum modulation is enabled by tying the SYNC/SPRD pin to INTVCC, which activates internal 25% triangle frequency modulation around the oscillator setpoint. This reduces peak EMI without requiring external clock sources or complex layout changes, unlike fixed-frequency or externally synchronized operation.
What fault protection modes does the ADPL76030EUFD#TRPBF offer during output short-circuit events?
The ADPL76030EUFD#TRPBF offers three short-circuit fault responses selectable via resistor on the SS pin: hiccup mode (no resistor), latch-off (499 kΩ), and keep-running (100 kΩ). These modes determine whether the device cycles on/off, shuts down permanently, or continues switching while limiting current.
Can the ADPL76030EUFD#TRPBF operate with input voltage equal to output voltage?
Yes, the ADPL76030EUFD#TRPBF operates seamlessly in buck-boost region where VIN ≈ VOUT (e.g., 12 V in / 12 V out). Its proprietary peak-buck/peak-boost current-mode control ensures stable regulation and low-noise transitions without discontinuity or loop instability at the crossover point.
