Product details
Overview
ADP3088ARM-REEL7 from Analog Devices is a 1 MHz, nonsynchronous PWM buck regulator with integrated 1 A power switch in MSOP-8 package, delivering 1.25 V to 10.5 V adjustable output voltage, ±3% regulation accuracy over temperature/line/load, and 100% duty cycle capability - used for local point-of-use DC/DC conversion in portable battery-powered systems.
For engineers reviewing the ADP3088ARM-REEL7 datasheet, ADP3088ARM-REEL7 pinout, ADP3088ARM-REEL7 application, or ADP3088ARM-REEL7 equivalent, key selection considerations include input voltage range (2.5 V to 11 V), thermal shutdown threshold (160°C), soft start time (250–600 ms), current limit (1.0–1.4 A), and power-saving mode activation at light load.
Technical Context
The ADP3088ARM-REEL7 implements current-mode PWM control with fixed 1 MHz oscillator, integrated error amplifier (gm = 480 mA/V), and slope-compensated modulator (gm = 1 A/V). It features cycle-by-cycle current limiting, internal 1.245 V reference (±1.8 mV accuracy), and proprietary power-saving mode triggered by integrated duty-ratio measurement below 14%.
Its nonsynchronous architecture requires an external Schottky rectifier; the DRV pin enables efficiency optimization by routing switch drive current to the output rail when VIN > VOUT + 1 V. Protection includes thermal shutdown at 160°C and automatic soft-start reset upon current-limit event.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | 1 MHz (enables use of small 10 µH inductors and 10 µF MLCCs) |
| Input Voltage Range | 2.5 V to 11 V (supports single-cell Li-ion up to 3S battery inputs) |
| Output Voltage Range | 1.25 V to 10.5 V (programmable via resistor divider on FB pin) |
| Current Limit Threshold | 1.0–1.4 A (cycle-by-cycle protection prevents damage during overload) |
| Reference Voltage Accuracy | 1.222–1.265 V (ensures ≤±3% output regulation across temp/line/load) |
| Soft Start Time | 250–600 ms (prevents inductor saturation and output overshoot at startup) |
| Quiescent Current | 150–250 µA (low-noise operation in active PWM mode; drops further in PSM) |
| Thermal Shutdown | 160°C (latching shutdown protects die; resumes operation after cooldown) |
Pinout & Package
ADP3088ARM-REEL7 is housed in an 8-lead MSOP package (3.0 mm × 3.0 mm, 0.65 mm pitch) with exposed pad for thermal enhancement. Dual IN and GND pins reduce PCB trace resistance and improve current handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 - IN | Power supply input | Must be connected in parallel; accepts 2.5–11 V; supplies internal bias and switch driver |
| 3, 6 - GND | Ground reference | Dual ground connections minimize ground bounce and improve stability |
| 4 - COMP | Compensation node / shutdown control | Open-drain input; pulling low disables regulator and reduces IQ to 15–40 µA |
| 5 - FB | Feedback voltage sense | Monitors output via resistor divider; regulates to 1.245 V reference |
| 7 - DRV | Switch driver return path | Connect to VOUT (not GND) when VIN > VOUT + 1 V to improve efficiency |
| 8 - SW | Switching node output | Drives external Schottky diode; peak voltage = VIN + Vf(diode); requires careful layout |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 1 A power switch | Eliminates need for external MOSFET; supports up to 750 mA continuous output with margin |
| Automatic PWM-to-power-saving mode transition | Reduces quiescent current at light load without external control circuitry |
| Fully integrated soft start | Prevents output overshoot and inrush stress using internal timer and offset injection |
| 100% duty cycle operation | Enables dropout operation down to VIN ≈ VOUT + 0.25 V (switch RDS(on) dependent) |
| Cycle-by-cycle current limit | Provides fast overcurrent protection independent of loop bandwidth or compensation |
| Slope compensation | Stabilizes current-mode control at high duty cycles (>50%) to prevent subharmonic oscillation |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62067DRVR | Synchronous 3-MHz buck; 600 mA output; 2.7–6 V input; no external diode required | Better efficiency at light load due to synchronous rectification; smaller solution size but higher cost | Preferred when board space is critical and input voltage is limited to 2.7–6 V |
| LT1935ES5#TRMPBF | Nonsynchronous 1.2-MHz buck; 1.25 A switch; 3.6–36 V input; wider VIN range | Supports industrial/high-voltage inputs; larger SOT-23-5 package; no DRV pin for efficiency tuning | Chosen when input exceeds 11 V or extended temperature validation is required beyond –40°C to +85°C |
Compared with TPS62067DRVR and LT1935ES5#TRMPBF, the ADP3088ARM-REEL7 offers unique trade-offs: its DRV pin enables dynamic efficiency tuning not found in either alternative, while its 2.5 V minimum input supports single-cell Li-ion systems where the others cannot operate.

FAQ
What is the maximum continuous output current supported by the ADP3088ARM-REEL7?
The ADP3088ARM-REEL7 is rated for 750 mA continuous output current under typical conditions (TA = 25°C, 4-layer PCB, proper thermal layout). Its internal 1 A power switch provides headroom for transient peaks, but sustained operation above 750 mA requires derating based on ambient temperature, copper area, and airflow per the θJA = 116°C/W (4-layer) specification.
Can the ADP3088ARM-REEL7 operate with an input voltage lower than 2.5 V?
No - the ADP3088ARM-REEL7 has a specified minimum input voltage of 2.5 V. Operation below this level is not guaranteed and may result in failure to start, unstable regulation, or undefined behavior. The device's internal bias circuitry and power switch require ≥2.5 V to function correctly across the full –40°C to +85°C temperature range.
How does the DRV pin affect efficiency in the ADP3088ARM-REEL7?
The DRV pin in the ADP3088ARM-REEL7 routes the bipolar switch's base drive current to the output rail instead of ground. When VIN > VOUT + 1 V, connecting DRV to VOUT reduces ground current by ~1–2 mA and improves full-load efficiency by 1–2% - verified in typical applications with 3.3 V output from 5 V input.
Is the ADP3088ARM-REEL7 RoHS compliant and lead-free?
Yes - the ADP3088ARM-REEL7 is RoHS-compliant and lead-free per Analog Devices' product change notice PCN-06-001. The MSOP-8 package uses matte tin lead finish, and the device meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) requirements for standard surface-mount assembly.
What external components are mandatory for basic operation of the ADP3088ARM-REEL7?
Four external components are mandatory: input capacitor (≥10 µF ceramic), output capacitor (≥10 µF ceramic), power inductor (e.g., 10 µH), and Schottky diode (e.g., 1N5817). Additionally, a resistor divider (RA/RB) on the FB pin is required to set output voltage; RA and RB must each be between 2 kΩ and 200 kΩ with ≤1% tolerance for accurate regulation.
