Product details
Overview
ADPL76030EUFD#PBF 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, with ±2% output voltage accuracy, 1.4 MHz fixed-frequency operation (adjustable 600 kHz–1.4 MHz), and spread spectrum frequency modulation for EMI reduction-designed for industrial telecom power supplies and battery-supercapacitor charging systems.
For engineers reviewing the ADPL76030EUFD#PBF datasheet, ADPL76030EUFD#PBF pinout, ADPL76030EUFD#PBF application, or ADPL76030EUFD#PBF equivalent, key selection considerations include its 4-switch single-inductor architecture enabling seamless buck/buck-boost/boost transitions, ±3% current-sense accuracy via ISP/ISN inputs, and integrated 5 V INTVCC regulator with 145 mA current limit-critical for high-density, low-noise power designs.
Technical Context
The ADPL76030EUFD#PBF implements a proprietary peak-buck/peak-boost current-mode control scheme that enables stable regulation across all three operating regions (VIN > VOUT, VIN ≈ VOUT, VIN < VOUT) without discontinuous transitions or refresh noise. Its dual-path sensing (LSP/LSN for buck-side inductor current; ISP/ISN for input/output current) supports independent CV/CC regulation with 100 mV full-scale current-sense threshold.
Internal 5 V INTVCC LDO powers gate drivers and control circuitry, while BST1/BST2 bootstrap supplies support high-side N-channel MOSFETs with 2.6 Ω pull-up and 1.4 Ω pull-down on TG1/TG2. The SS pin provides programmable soft-start and selectable short-circuit response modes (hiccup, latch-off, or keep-running) via external resistor configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 4 V to 55 V - supports wide-input industrial and telecom rails, including 24 V, 48 V, and 54 V systems without pre-regulation. |
| VOUT Range | 0 V to 55 V - enables bidirectional voltage regulation for battery charging, supercapacitor balancing, and variable-output supplies. |
| Switching Frequency | 600 kHz to 1.4 MHz - adjustable via RT resistor; internal oscillator at 1.4 MHz enables compact magnetics and high power density. |
| Output Voltage Accuracy | ±2% over −40°C to +125°C - ensures stable regulation under thermal stress in embedded and outdoor equipment. |
| Current Sense Accuracy | ±3% for input or output current monitoring - enables precise CC mode for battery charge control and load protection. |
| Spread Spectrum | 25% triangle modulation - reduces peak EMI by spreading switching energy across a 21–25% bandwidth above base frequency. |
| INTVCC Regulator | 5.0 V ±1.5%, 145 mA limit - powers internal logic and gate drivers; eliminates need for external bias supply. |
Pinout & Package
ADPL76030EUFD#PBF 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 soldering to PCB ground plane for thermal management (θJA = 43°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TG1, TG2 | Buck/Boost top gate drivers | Drive high-side N-MOSFET gates with swing from SWx to BSTx; 2.6 Ω pull-up enables fast turn-on in high-frequency operation. |
| BG1, BG2 | Buck/Boost bottom gate drivers | Drive low-side N-MOSFET gates from GND to INTVCC; 1.2 Ω pull-down ensures rapid turn-off and minimizes shoot-through risk. |
| LSP/LSN | Buck-side inductor current sense | Kelvin-connected inputs for accurate peak-buck current measurement; common-mode range up to 55 V supports high-side sensing. |
| ISP/ISN | Input/output current monitor | Dual-role sense inputs for CV/CC regulation; ISMON outputs 10×(VISP−VISN)+0.25 V for analog current feedback. |
| FB | Voltage loop feedback | Regulates VOUT to 1.00 V reference; ±10% PGOOD window and fault thresholds (0.25 V short, 1.10 V overvoltage) enable robust protection. |
| SYNC/SPRD | Frequency control | GND = internal oscillator; INTVCC = 25% spread spectrum; external clock = synchronization - no external components needed for EMI reduction. |
| SS | Soft-start & fault mode select | Capacitor sets ramp time; resistor to VREF selects hiccup (no R), latch-off (499 kΩ), or keep-running (100 kΩ) during short-circuit. |
Key Features
| Feature | Design Value |
|---|---|
| 4-switch single-inductor architecture | Enables seamless transition between buck, buck-boost, and boost modes without voltage discontinuity or audible noise-ideal for dynamic load applications like telecom rectifiers. |
| Proprietary peak-buck/peak-boost control | Eliminates top MOSFET refresh noise in both buck and boost regions, reducing conducted EMI and improving signal integrity in sensitive analog subsystems. |
| Integrated 5 V INTVCC LDO | Delivers 145 mA at 5.0 V ±1.5%, powering gate drivers and internal circuitry-removes need for external bias rail and simplifies BOM. |
| Programmable current-sense threshold | CTRL pin adjusts ISP/ISN full-scale threshold from 5 mV to 100 mV linearly (0.3–1.15 V), enabling precise CC setpoints for battery charge profiles. |
| Three short-circuit protection modes | Selectable via SS-to-VREF resistor: hiccup (no resistor), latch-off (499 kΩ), or continuous operation (100 kΩ)-supports fail-safe or fault-tolerant system requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck-boost controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT8708IMSE#PBF | 40 V max VIN, no spread spectrum, requires external VREF for current sense; 12-lead MSOP vs. 28-lead QFN. | Limited to lower-voltage industrial systems; lacks integrated EMI reduction features and dual current-sense paths. | Choose when board space is constrained and EMI requirements are less stringent; verify external bias and compensation network compatibility. |
| TPS630702RTER | 20 V max VIN, integrated MOSFETs, 2 A max output; no ISP/ISN monitoring or programmable short-circuit modes. | Suitable only for low-power portable electronics; cannot replace ADPL76030EUFD#PBF in high-voltage or high-current industrial charging. | Select only for cost-sensitive, low-power (<10 W) applications where integrated FETs reduce component count and layout complexity. |
Compared with LT8708IMSE#PBF and TPS630702RTER, the ADPL76030EUFD#PBF delivers higher voltage capability (55 V), built-in spread spectrum, dual current-sense architecture, and field-configurable fault response-making it uniquely suited for ruggedized telecom and battery-energy systems where reliability, EMI compliance, and operational flexibility are critical.

FAQ
What is the maximum input voltage rating for the ADPL76030EUFD#PBF?
The ADPL76030EUFD#PBF has an absolute maximum VIN rating of 58 V per the datasheet's Absolute Maximum Ratings table. Its operational input voltage range is specified from 4 V to 55 V, making it suitable for 48 V telecom systems and automotive load-dump tolerant designs. Exceeding 58 V risks permanent damage, and operation above 55 V is outside guaranteed specifications.
Does the ADPL76030EUFD#PBF support both constant-voltage and constant-current regulation?
Yes, the ADPL76030EUFD#PBF supports dual-loop regulation: FB pin enables precise constant-voltage control (±2% accuracy), while ISP/ISN inputs with ISMON output provide ±3% accurate constant-current regulation for input or output current limiting-enabling battery charging, LED driver, and programmable power supply applications.
How is spread spectrum frequency modulation enabled on the ADPL76030EUFD#PBF?
Spread spectrum is activated by tying the SYNC/SPRD pin to INTVCC, which configures the internal oscillator for 25% triangle modulation above the base frequency set by the RT resistor. No external clock or timing components are required-this feature reduces peak EMI by 10–15 dB compared to fixed-frequency operation, easing EMC certification.
What package type and thermal characteristics does the ADPL76030EUFD#PBF use?
The ADPL76030EUFD#PBF uses a 28-lead 4 mm × 4 mm plastic QFN package with exposed thermal pad (Pin 29 = GND). Its thermal resistance is θJA = 43°C/W and θJC = 3.4°C/W when properly soldered to a 4-layer PCB with ≥2 in² copper pour under the exposed pad-critical for sustaining 125°C junction temperature in continuous 4 A output applications.
Can the ADPL76030EUFD#PBF operate in buck-only or boost-only mode?
Yes, the ADPL76030EUFD#PBF operates seamlessly in buck-only (VIN > VOUT), boost-only (VIN < VOUT), and buck-boost (VIN ≈ VOUT) modes without control loop reconfiguration or external mode-select pins. Its proprietary peak-buck/peak-boost current-mode architecture automatically adapts switching behavior and gate drive timing to maintain regulation and efficiency across all regions.
