Product details
Overview
ADP3607AR-5 from Analog Devices is a 50 mA regulated switched-capacitor voltage doubler IC that generates a stable 5 V output from 3.0 V to 5.0 V input, featuring ±5% output accuracy, 250 kHz switching frequency, and SO-8 packaging - used in portable instruments and battery-powered devices requiring compact, inductorless DC/DC boost.
For engineers reviewing the ADP3607AR-5 datasheet, ADP3607AR-5 pinout, ADP3607AR-5 application, or ADP3607AR-5 equivalent, key selection criteria include input voltage range (3.0–5.0 V), regulated fixed 5 V output, shutdown control via SD pin, thermal performance up to +85°C, and compatibility with low-ESR ceramic/tantalum capacitors for minimal ripple.
Technical Context
The ADP3607AR-5 implements a two-phase charge-pump topology driven by an internal 500 kHz oscillator, producing a 250 kHz effective switching frequency to minimize external capacitor size. It uses internal precision resistors for regulation and supports remote sensing via VSENSE to compensate for PCB trace IR drop.
Operation requires three external capacitors: CP (pump), CO (output), and CIN (input bypass), with recommended values ≥4.7 µF and low ESR. Shutdown mode reduces quiescent current to 150 µA by disabling the oscillator when SD is logic high.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0 V ±5% at 10–50 mA load ensures stable rail for logic or analog circuitry without external feedback components. |
| Input Voltage Range | 3.0 V to 5.0 V enables direct operation from single Li-ion, NiMH, or regulated 3.3 V/5 V supplies. |
| Max Output Current | 50 mA continuous output supports moderate-power peripherals like sensors, small displays, or RF modules. |
| Switching Frequency | 250 kHz nominal allows use of compact 4.7 µF ceramic/tantalum capacitors instead of bulky electrolytics or inductors. |
| Shutdown Current | 150 µA max in shutdown mode preserves battery life in sleep states of portable equipment. |
| Operating Temp | –40°C to +85°C ambient rating supports industrial and consumer applications without derating. |
| Output Ripple | 31 mV peak-to-peak at 50 mA load with 4.7 µF CO defines minimum filtering requirements for noise-sensitive circuits. |
Pinout & Package
ADP3607AR-5 is housed in an 8-lead SOIC (SO-8) package with standard 1.27 mm pitch, JEDEC MS-012AC compliant, and rated θJA = 150°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (CP+) | Pump capacitor positive terminal | Connects to positive lead of CP; carries bidirectional 100 mA peak current during charge transfer cycles. |
| 2 (VIN) | Positive input supply | Accepts 3.0–5.0 V input; requires local 4.7 µF low-ESR bypass capacitor to suppress switching transients. |
| 3 (CP–) | Pump capacitor negative terminal | Completes CP charging path; tied to VIN during phase one, to VOUT during phase two. |
| 4 (SD) | Logic-level shutdown control | Active-high TTL/CMOS input; >2.4 V disables oscillator and reduces IQ to 150 µA. |
| 5 (VSENSE) | Output voltage sense feedback | Enables remote sensing at load point to improve load regulation; connect directly to VOUT unless precision compensation needed. |
| 6 (NC) | No connection | Internally unconnected; must remain floating - no external tie required or permitted. |
| 7 (GND) | Power and signal ground reference | Single-point ground connection for all capacitors and IC substrate; critical for low-noise operation. |
| 8 (VOUT) | Regulated 5 V output | Delivers up to 50 mA; requires ≥4.7 µF low-ESR output capacitor to limit ripple and maintain regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Inductorless architecture | Eliminates magnetic components and EMI concerns, enabling ultra-thin PCB designs for space-constrained portable systems. |
| Integrated 500 kHz oscillator | Generates precise 250 kHz charge-pump clock without external timing components, reducing BOM count and layout sensitivity. |
| VSENSE remote sensing | Compensates for up to 100 mΩ PCB trace resistance between VOUT and load, maintaining ±5% regulation under dynamic load conditions. |
| Low-ESR capacitor optimization | Validated with 4.7 µF ceramic/tantalum capacitors; enables <31 mV ripple at full 50 mA load without additional filtering stages. |
| Thermal robustness | Rated for continuous operation at +85°C ambient with 150°C/W junction-to-ambient thermal resistance in SO-8 package. |

Use Value: Input range down to 3.0 V allows operation even with USB voltage sag; VSENSE improves regulation at adapter PCB edge connectors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar regulated charge-pump voltage doubler applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX680ESA+ | Fixed ±5 V dual output; 20 mA per rail; 100 kHz switching; SO-8 package. | Provides complementary negative rail - unsuitable for single-rail 5 V boost-only needs. | Select only if dual-supply generation is required; lower current and slower switching increase capacitor size. |
| TPS60403DBVR | Fixed 5 V output; 60 mA; 500 kHz switching; SOT-23-5 package; no VSENSE pin. | Lacks remote sensing and uses smaller 5-pin package - limits layout flexibility and load regulation precision. | Prefer for ultra-low-cost, space-constrained designs where ±5% regulation at load point is not critical. |
Compared with MAX680ESA+ and TPS60403DBVR, ADP3607AR-5 uniquely combines 50 mA capability, VSENSE-based load regulation, and 250 kHz operation in SO-8 - making it optimal for portable systems demanding both precision and compact inductorless design.

FAQ
What is the maximum output current specification for ADP3607AR-5?
The ADP3607AR-5 delivers up to 50 mA continuous output current while maintaining ±5% regulation across its specified input range (3.0–5.0 V) and temperature range (–40°C to +85°C). This rating is validated with 4.7 µF low-ESR output and pump capacitors, and output voltage drops to 4.75 V minimum at 50 mA load per the datasheet's VO specification table.
Does ADP3607AR-5 require an inductor in its application circuit?
No, ADP3607AR-5 does not require an inductor. It uses a switched-capacitor (charge-pump) architecture with internal switches and an oscillator to double the input voltage. The design relies solely on three external capacitors - CP (pump), CO (output), and CIN (input bypass) - eliminating magnetic components and associated EMI concerns.
How does the VSENSE pin function in ADP3607AR-5?
The VSENSE pin in ADP3607AR-5 provides remote output voltage sensing to improve load regulation. When connected directly to the load point (not just VOUT), it compensates for IR drop across PCB traces. For standard use, VSENSE is tied to VOUT; for precision applications, routing VSENSE separately minimizes regulation error caused by trace resistance up to ~100 mΩ.
What is the shutdown behavior of ADP3607AR-5?
When the SD pin of ADP3607AR-5 is driven to logic high (>2.4 V), the internal oscillator stops, halting switching activity and reducing quiescent current to 150 µA typical. The output remains at approximately VIN minus one Schottky diode drop due to the internal protection diode. Pulling SD low or grounding it enables normal operation.
Which capacitor technologies are recommended for ADP3607AR-5?
Analog Devices recommends low-ESR multilayer ceramic (MLCC) or solid tantalum capacitors for CP, CO, and CIN in ADP3607AR-5 applications. MLCCs (e.g., Murata GRM, TOKIN MLCC) offer excellent high-frequency performance and stability; tantalum types (e.g., Sprague 675D, Mallory TDC) provide better low-temperature ESR. Aluminum electrolytics are discouraged due to higher ESR and aging effects.
