Product details
Overview
ADP1607ACPZN-R7 from Analog Devices is a synchronous, fixed-frequency 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, features 23 µA quiescent current in PFM mode, and operates at 2 MHz to enable compact 2.2 µH inductor and 10 µF ceramic capacitor designs-ideal for miniature hard disk power supplies and LED status indicators.
For engineers reviewing the ADP1607ACPZN-R7 datasheet, ADP1607ACPZN-R7 pinout, ADP1607ACPZN-R7 application, or ADP1607ACPZN-R7 equivalent, key selection criteria include its 0.9 V start-up voltage, true shutdown output isolation, internal soft start and compensation, thermal shutdown (150°C), and compatibility with low-ESR ceramic capacitors and chip-scale inductors in space-constrained layouts.
Technical Context
The ADP1607ACPZN-R7 employs current-mode PWM control with auto PFM-to-PWM transition to optimize light-load efficiency while maintaining tight regulation. Its integrated NMOS/PMOS synchronous rectifier eliminates external diode losses, and internal compensation supports stable operation with only two external components: a 2.2 µH inductor and 10 µF input/output ceramics.
It features logic-controlled enable with 0.25 V low / 0.8 V high thresholds, fixed 1 A typical current limit independent of duty cycle, and thermal shutdown active only in PWM mode. The 2 MHz switching frequency enables sub-3 mm² solution size while minimizing EMI through controlled edge rates and low-noise PFM operation below ~10 mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching Frequency | 2 MHz ±10% - enables use of small 2.2 µH inductors and 10 µF ceramic caps, reducing board area and height. |
| Input Voltage Range | 0.8 V to VOUT - supports single-cell alkaline/NiMH (0.8 V cutoff) and extends runtime in low-battery conditions. |
| Output Voltage Range | 1.8 V to 3.3 V - set via external resistor divider; FB pin reference is 1.259 V (±2.4%) for precise regulation. |
| Quiescent Current | 23 µA (typical, TA = −40°C to +85°C) - minimizes battery drain in standby without compromising startup capability. |
| Start-Up Voltage | 0.9 V (guaranteed by design) - ensures reliable boot from deeply discharged 1-cell batteries. |
| Current Limit | 1 A typical - provides robust short-circuit protection without external sensing, independent of duty cycle. |
| Efficiency | Up to 96% - achieved via synchronous rectification and low RDS(ON) (116 mΩ NMOS / 155 mΩ PMOS @ 500 mA). |
| Shutdown Current | 0.06 µA (typical, TA = −40°C to +45°C) - enables ultra-low-power system sleep states with true output isolation. |
Pinout & Package
ADP1607ACPZN-R7 is housed in a 2 mm × 2 mm, 6-lead LFCSP_UD package with exposed pad (EPAD) that must be soldered to GND for thermal and electrical performance. Pin 1 is marked by a corner chamfer; the EPAD is electrically connected to GND and improves thermal resistance (θJA = 66.06°C/W on 4-layer PCB).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Analog & power supply input | Accepts 0.8 V–VOUT; connects to input capacitor and inductor source; requires local 10 µF ceramic bypass. |
| EN | Logic-controlled enable | Active-high shutdown control; 0.25 V low / 0.8 V high thresholds; drives to GND for 0.06 µA shutdown current. |
| FB | Feedback voltage sense | Monitors output via resistor divider; internal 1.259 V reference; 0.1 µA bias current affects high-value dividers. |
| GND | Analog & power ground | Common return for VIN, VOUT, FB, and EN; Kelvin connection required for feedback network stability. |
| SW | Switch node | Drain connection of NMOS/PMOS power switches; high dv/dt node requiring short, low-inductance routing to inductor. |
| VOUT | Regulated output | Source of PMOS switch; supplies load; requires local 10 µF ceramic capacitor with X5R/X7R dielectric. |
| EPAD | Exposed thermal pad | Must be soldered to GND plane with ≥4 thermal vias; critical for thermal management and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Synchronous rectification | Integrated NMOS/PMOS switches eliminate Schottky diode loss, enabling >96% peak efficiency and reducing BOM count. |
| Auto PFM/PWM mode | Seamlessly transitions between pulse-frequency modulation (light loads) and fixed 2 MHz PWM (medium/heavy loads) to maximize efficiency across full load range. |
| True output isolation | Internally disconnects VOUT from VIN during shutdown using bulk PMOS gate control, preventing backfeed and enabling safe system-level power sequencing. |
| Internal soft start & compensation | Fixed 1.3 ms soft-start time prevents inrush current; fully compensated loop requires no external components for stable 2.2 µH/10 µF designs. |
| Thermal shutdown | Activates at 150°C (typical) with 15°C hysteresis; protects device under overload or poor thermal conditions; only active in PWM mode. |
| Low 0.9 V start-up | Guaranteed-by-design minimum start voltage allows operation from single-cell alkaline/NiMH down to end-of-life voltage, extending usable battery capacity. |

FAQ
What is the minimum input voltage required to start up the ADP1607ACPZN-R7?
The ADP1607ACPZN-R7 has a guaranteed-by-design minimum start-up voltage of 0.9 V, allowing reliable operation from single-cell alkaline or NiMH batteries even near end-of-life. This value is not production tested but verified through characterization and simulation across temperature and process corners. The ADP1607ACPZN-R7 will not start below this threshold, and VIN must never exceed VOUT once enabled.
Does the ADP1607ACPZN-R7 require external compensation components?
No, the ADP1607ACPZN-R7 features fully internal compensation optimized for use with a 2.2 µH inductor and 10 µF ceramic input/output capacitors. Adding external compensation components is unnecessary and may destabilize the control loop. The internal compensation delivers stable operation across the full 1.8 V–3.3 V output range and 0.8 V–VOUT input range without requiring additional resistors or capacitors.
How does the ADP1607ACPZN-R7 achieve true output isolation during shutdown?
The ADP1607ACPZN-R7 achieves true output isolation by actively controlling the bulk terminal of its internal PMOS switch during shutdown. When EN is pulled low, the device forces the PMOS gate to a state that fully turns off the conduction path from VIN to VOUT, preventing backfeed and allowing VOUT to discharge to ground through the load. This feature is confirmed in the datasheet's "Input to Output Isolation" section and distinguishes ADP1607ACPZN-R7 from boost converters with passive diode-based isolation.
What is the recommended inductor for the ADP1607ACPZN-R7, and why?
Analog Devices recommends a 2.2 µH shielded chip inductor with ≤100 mΩ DCR, such as the TDK VLF302512MT-2R2M or Coilcraft XFL3012-222. This value is optimized for the ADP1607ACPZN-R7's 2 MHz switching frequency, delivering best-in-class efficiency, thermal performance, and transient response. Inductors outside this specification risk instability, excessive ripple, or reduced efficiency due to mismatched peak current handling and core saturation characteristics.
Can the ADP1607ACPZN-R7 operate with ceramic output capacitors, and what type is recommended?
Yes, the ADP1607ACPZN-R7 is explicitly designed for ceramic output capacitors. X5R or X7R dielectric 10 µF, 4 V-rated MLCCs are recommended-such as the Murata LQM2HPN2R2MG0 or TDK C3216X5R0J106K-due to their low ESR, low ESL, and stable capacitance over temperature and DC bias. Y5V dielectrics are discouraged because of significant capacitance loss under bias, which degrades output regulation and transient response.
