Product details
Overview
ADP2360ACPZ-R7 from Analog Devices is a high-efficiency, synchronous step-down DC-DC regulator supporting 4.5 V to 60 V input and delivering up to 50 mA continuous output current with factory-programmable 3.3 V or 5.0 V fixed outputs or adjustable 0.8 V to VIN regulation. It features PFM control, 100% duty cycle operation, power-good (PG) flag, and thermal shutdown - deployed in 4–20 mA loop-powered sensors and HART modems where wide VIN and ultra-low quiescent current are critical.
For engineers reviewing the ADP2360ACPZ-R7 datasheet, ADP2360ACPZ-R7 pinout, ADP2360ACPZ-R7 application, or ADP2360ACPZ-R7 equivalent, key selection criteria include input voltage range (4.5–60 V), output current capability (50 mA), quiescent current in sleep mode (12 µA), UVLO thresholds (4.3–4.5 V rising), and LFCSP-8 package compatibility with thermal vias for industrial ambient operation up to +125°C.
Technical Context
The ADP2360ACPZ-R7 uses discontinuous conduction mode (DCM) with single-pulse peak-current-controlled PFM to minimize input/output ripple while enabling stable light-load efficiency. Its ITH pin allows resistor-programmable peak inductor current (50–140 mA), directly shaping switching frequency, output ripple, and inductor size trade-offs.
It integrates precision enable logic (1 V rising threshold, 50 mV hysteresis), programmable soft start via external capacitor, undervoltage lockout, and open-drain power-good output with 0.76 V rising threshold (for 3.3 V model). The internal 0.8 V feedback reference enables accurate output regulation without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5 V to 60 V - supports direct connection to industrial 24 V, 48 V, and legacy 60 V bus rails without pre-regulation. |
| Output Current | 50 mA continuous - sufficient for powering low-power microcontrollers, transceivers, and analog front-ends in loop-powered systems. |
| Quiescent Current | 12 µA typical in sleep mode - enables multi-year battery life in always-on sensor nodes with intermittent wake-up cycles. |
| Efficiency | 90% at 9 VIN/3.3 VOUT/10 mA - minimizes self-heating in sealed enclosures and extends thermal margin in +85°C ambient environments. |
| UVLO Threshold | 4.3 V (rising), 4.2 V (falling) - prevents erratic startup during brown-out conditions on unregulated supplies like solar or battery inputs. |
| Power-Good Output | Open-drain PG with 0.76 V rising threshold (3.3 V model) - provides system-level reset or sequencing signal compatible with 3.3 V logic without level-shifting. |
| Thermal Shutdown | 150°C rising threshold with 15°C hysteresis - protects against sustained overload or poor PCB thermal design while allowing safe recovery after cooling. |
Pinout & Package
ADP2360ACPZ-R7 is housed in a 3 mm × 3 mm, 8-lead LFCSP package with exposed pad (EPAD) requiring solder connection to AGND plane for thermal and electrical integrity. Thermal resistance θJA = 62.7°C/W under JEDEC 4-layer board conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - EN | Enable input with precision threshold | Accepts 0–60 V logic; activates regulator when voltage exceeds 1.0 V (±50 mV hysteresis); supports direct connection to microcontroller GPIO or system power rail. |
| 2 - PG | Open-drain power-good output | Signals valid regulation by pulling high via external pull-up; sinks current when VFB < 0.76 V (3.3 V model); rated for 60 V max voltage. |
| 3 - ITH | Peak inductor current programming node | Resistor-to-ground sets IPEAK from 50 mA (open) to 140 mA (0 Ω); determines switching frequency, ripple, and inductor sizing. |
| 4 - FB | Feedback input | Monitors output voltage divider; internal 0.8 V reference enables precise regulation; draws only 0.1 µA leakage in adjustable models. |
| 5 - SS | Soft-start timing node | Charged by 1 µA internal current source; controls ramp rate of output voltage to prevent inrush current and overshoot during power-up. |
| 6 - PGND | Power ground return | Low-impedance path for NMOS switch and inductor return; must be separated from AGND except at single-point EPAD connection. |
| 7 - SW | Switch node | Drain connection of internal PMOS/NMOS pair; carries high di/dt switching current; requires tight layout with minimal loop area to reduce EMI. |
| 8 - VIN | Main input supply | Accepts 4.5–60 V; requires local 10 µF ceramic capacitor to PGND; voltage rating of external components must exceed 60 V. |
| 9 - AGND (EPAD) | Analog ground / thermal pad | Exposed copper pad beneath package; must be soldered to solid ground plane with ≥4 thermal vias for thermal dissipation and noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| No external compensation required | Internal Type-II compensation eliminates need for external RC network - reduces BOM count and layout sensitivity in space-constrained designs. |
| 100% duty cycle operation | Enables dropout-free regulation down to VOUT ≈ VIN - critical for maintaining output during input voltage sag in industrial fieldbus applications. |
| Adjustable peak current limit (IPEAK) | Programmable from 50 mA to 140 mA via single resistor - allows optimization of efficiency vs. ripple vs. inductor size without changing IC. |
| Low shutdown current (<4 µA) | Minimizes battery drain in always-connected but inactive systems - essential for remote wireless sensors powered by primary lithium cells. |
| Integrated power-good (PG) indicator | Open-drain NMOS with 60 V rating - enables direct interface to PLC input modules or microcontroller interrupt pins without external level shifters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-input-voltage, low-output-current buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM5164QWRXMRQ1 | Wider input (3–100 V), higher output current (150 mA), but requires external compensation and has 250 µA quiescent current. | Automotive AEC-Q100 qualified; suited for vehicle body electronics, not optimized for ultra-low-IQ industrial sensors. | Choose LM5164QWRXMRQ1 only if >100 V input or AEC-Q100 compliance is mandatory; ADP2360ACPZ-R7 offers superior light-load efficiency and simpler design. |
| TPS63001DRCR | Buck-boost topology (1.8–5.5 V input), 600 mA output, 25 µA quiescent current - cannot support >6 V input or 60 V absolute max. | Designed for single-cell battery systems; lacks UVLO, PG, and high-VIN robustness needed for industrial field devices. | TPS63001DRCR is unsuitable for 24/48 V bus applications; ADP2360ACPZ-R7 remains the only viable choice for 4.5–60 V, 50 mA, low-IQ requirements. |
Compared with LM5164QWRXMRQ1 and TPS63001DRCR, ADP2360ACPZ-R7 uniquely balances 60 V input tolerance, 12 µA sleep-mode current, integrated PG, and zero-compensation simplicity - making it the optimal fit for space- and power-constrained industrial loop-powered systems.

FAQ
What is the maximum input voltage rating for the ADP2360ACPZ-R7?
The ADP2360ACPZ-R7 has an absolute maximum input voltage rating of +61 V on the VIN pin, with guaranteed operation from 4.5 V to 60 V. This makes it suitable for direct connection to industrial 24 V and 48 V distribution buses, including transient-tolerant applications where voltage spikes may occur. Operation beyond 60 V is not recommended for long-term reliability.
Does the ADP2360ACPZ-R7 require external compensation components?
No, the ADP2360ACPZ-R7 does not require external compensation components. Its internal control loop is fully compensated, enabling stable regulation with only three external components for fixed-output configurations: input capacitor, output capacitor, and inductor. This simplifies design, reduces footprint, and improves consistency across production units.
How is the output voltage configured on the ADP2360ACPZ-R7?
The ADP2360ACPZ-R7 is available in both fixed-output (3.3 V or 5.0 V) and adjustable-output variants. For fixed versions like ADP2360ACPZ-R7, internal feedback resistors set the output - no external resistors are needed. For adjustable versions, output voltage is set using an external resistor divider from VOUT to FB and AGND, referenced to the internal 0.8 V bandgap.
What is the purpose of the ITH pin on the ADP2360ACPZ-R7?
The ITH pin on the ADP2360ACPZ-R7 programs the peak inductor current limit (IPEAK) from 50 mA (open circuit) to 140 mA (0 Ω resistor). This adjustment directly influences switching frequency, output voltage ripple, and inductor sizing - allowing designers to optimize for efficiency, size, or transient response without changing the IC or layout.
Can the ADP2360ACPZ-R7 operate with 100% duty cycle, and what does that mean for system design?
Yes, the ADP2360ACPZ-R7 supports true 100% duty cycle operation, meaning the high-side PMOS remains continuously on when VIN ≈ VOUT. This avoids dropout and maintains regulation during input voltage sags. However, output current is then limited to ~50% of IPEAK, so designers must ensure IPEAK is set sufficiently high to sustain required load under worst-case input conditions.
