Product details
Overview
ADP1607ACPZN001-R7 from Analog Devices is a synchronous boost DC-DC converter optimized for portable battery-powered systems. It delivers adjustable 1.8 V to 3.3 V output from 0.8 V–VOUT input, achieves up to 96% efficiency at 2 MHz switching frequency, features 23 µA quiescent current in PFM mode, and integrates synchronous rectification and internal compensation. It powers low-voltage peripherals in single-cell alkaline/NiMH devices.
For engineers reviewing the ADP1607ACPZN001-R7 datasheet, ADP1607ACPZN001-R7 pinout, ADP1607ACPZN001-R7 application, or ADP1607ACPZN001-R7 equivalent, key selection criteria include its 0.9 V start-up voltage, 1 A current limit, true shutdown output isolation, thermal shutdown protection, and compatibility with 2.2 µH inductors and 10 µF ceramic capacitors in space-constrained designs.
Technical Context
The ADP1607ACPZN001-R7 implements a current-mode PWM control architecture with auto PFM-to-PWM transition logic, enabling stable regulation across load ranges while minimizing light-load power loss. Its integrated NMOS/PMOS power switches feature 116 mΩ and 155 mΩ typical on-resistance at 500 mA, respectively, and operate with fixed 2 MHz switching frequency for compact external component sizing.
Internal soft start, fixed 1 A current limit, and thermal shutdown (150°C activation, 15°C hysteresis) are embedded without external components. The feedback pin references a precise 1.259 V internal voltage, supporting accurate output setting via external resistor divider, and the EN pin provides logic-controlled enable/disable with 0.25 V low / 0.8 V high thresholds.
Key Specifications

|---|---|
| Switching Frequency | 2 MHz ±10% - enables use of small 2.2 µH inductors and 10 µF ceramic capacitors. |
| Input Voltage Range | 0.8 V to VOUT - supports operation down to single-cell alkaline/NiMH discharge voltage. |
| Output Voltage Range | 1.8 V to 3.3 V - adjustable via external resistor divider on FB pin. |
| Quiescent Current | 23 µA (typical, nonswitching) - extends battery life in standby or light-load states. |
| Current Limit | 1 A (typical) - sets maximum switch conduction capability and defines peak inductor current handling. |
| Start-Up Voltage | 0.9 V (min) - ensures reliable startup from deeply discharged batteries. |
| Efficiency | Up to 96% - achieved via synchronous rectification eliminating Schottky diode losses. |
| Shutdown Current | 0.06 µA (typical) - minimizes system leakage when disabled. |
Pinout & Package
ADP1607ACPZN001-R7 is housed in a 2 mm × 2 mm, 6-lead LFCSP package with exposed pad (EPAD) requiring connection to GND for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Analog and power supply input | Accepts 0.8 V–VOUT input; connects to input capacitor and battery source. |
| EN | Logic-controlled enable | Drives high (>0.8 V) to activate regulator; low (<0.25 V) forces shutdown with 0.06 µA IQSD. |
| FB | Output voltage feedback | Senses divided VOUT; internal 1.259 V reference enables precise output setting (1.8–3.3 V). |
| GND | Analog and power ground | Reference node for all circuitry; must be connected to EPAD and system ground plane. |
| SW | Switch node | Drain connection of NMOS and source of PMOS; drives external inductor and carries high di/dt current. |
| VOUT | Regulated output | Delivers 1.8–3.3 V to load; requires 10 µF ceramic capacitor to ground for stability and ripple suppression. |
| EPAD | Exposed thermal pad | Mandatory GND connection for thermal dissipation and EMI reduction; soldered with thermal vias. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Integrated NMOS/PMOS switches eliminate external Schottky diode, improving efficiency by ~5–10% at medium loads. |
| Auto PFM/PWM mode | Automatically transitions between pulse-frequency modulation (light load) and fixed 2 MHz PWM (heavy load) to optimize efficiency across operating range. |
| True output isolation | Internally disconnects VOUT from VIN during shutdown, preventing backfeed and enabling safe system-level power sequencing. |
| Internal compensation | Eliminates need for external compensation network-designed for stable operation with 2.2 µH inductor and 10 µF ceramic capacitors. |
| Thermal shutdown | Activates at 150°C junction temperature (15°C hysteresis) only in PWM mode, protecting against sustained overload or poor PCB thermal design. |
| Low start-up voltage | 0.9 V minimum allows operation from partially depleted single-cell alkaline or NiMH batteries without brownout. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous boost converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61200DRCT | Fixed 3.3 V output; 0.3 V start-up; 1.2 MHz switching; no PFM mode; 2.5 A current limit. | Better for ultra-low-voltage start-up but less flexible output adjustment and lower switching frequency. | Select when fixed 3.3 V output and sub-0.3 V start-up are required, and board area permits larger inductor. |
| MAX8648ETA+ | Adjustable 2.5–5.5 V output; 0.7 V start-up; 2.5 MHz switching; 1.2 A current limit; no thermal shutdown. | Wider output range and higher frequency, but lacks TSD and has higher quiescent current (45 µA). | Choose for higher output voltage needs and tighter layout constraints, accepting trade-off in thermal protection and light-load efficiency. |

FAQ
What is the minimum input voltage required for ADP1607ACPZN001-R7 to start switching?
The ADP1607ACPZN001-R7 guarantees start-up at 0.9 V under RMIN = 22 Ω load condition. This allows reliable operation from single-cell alkaline or NiMH batteries even at end-of-discharge. Operation below 0.9 V is not functional-no switching occurs until input reaches this threshold. The 0.8 V lower bound in the operating range applies only after startup is achieved.
How is the output voltage set on ADP1607ACPZN001-R7?
The ADP1607ACPZN001-R7 uses an external resistor divider (R1 from VOUT to FB, R2 from FB to GND) to set output voltage between 1.8 V and 3.3 V. The FB pin references an internal 1.259 V (typical) bandgap, so VOUT = 1.259 V × (1 + R1/R2) + (IFB × R1). For accuracy, R1 and R2 should be between 100 kΩ and 1 MΩ to minimize error from FB pin current (0.1 µA typical).
Does ADP1607ACPZN001-R7 support automatic mode switching between PFM and PWM?
Yes, ADP1607ACPZN001-R7 operates in auto mode, dynamically transitioning between pulse-frequency modulation (PFM) at light loads and fixed 2 MHz PWM at medium/heavy loads. This optimizes efficiency across the full load range-PFM reduces quiescent current to 23 µA, while PWM ensures tight regulation and fast transient response above ~10 mA load.
What thermal protection does ADP1607ACPZN001-R7 provide?
ADP1607ACPZN001-R7 includes thermal shutdown (TSD) that activates at 150°C junction temperature (typical) with 15°C hysteresis, turning off power switches until die temperature falls to ~135°C. Critically, TSD is active only in PWM mode-not during PFM or shutdown-ensuring protection during sustained high-load operation while preserving low-power behavior in sleep states.
Can ADP1607ACPZN001-R7 be used with ceramic output capacitors?
Yes, ADP1607ACPZN001-R7 is explicitly designed for use with 10 µF X5R or X7R ceramic output capacitors rated ≥4 V. Its internally compensated control loop ensures stability with low-ESR ceramics. Avoid Y5V types due to capacitance drift with temperature and bias; account for DC bias derating-e.g., a 10 µF/6.3 V X7R may deliver only ~6–7 µF at 3.3 V bias, so select higher voltage rating if needed.
