ADP2360ACPZ-R7 Übersicht
A synchronous buck (step-down) DC-DC converter is a switching regulator topology that uses MOSFET switches to chop an input voltage and an LC filter to reconstruct a lower, well-regulated DC rail. DCM operation means the inductor current returns to zero each switching cycle, eliminating reverse-current losses and enabling high efficiency at light loads - a critical attribute when the source current itself is capped at a few milliampere.
Key features include 60V maximum input voltage with built-in over-voltage protection, 4.5V minimum input for cold-start, an adjustable output from 0.8V to VIN, internal high-side and low-side synchronous MOSFETs, and 100 percent duty-cycle capability for low-dropout pass-through. The regulator requires only an inductor and small ceramic capacitors, simplifying BOM and shrinking the footprint.
The architecture integrates a peak-current-mode controller with DCM boundary detection, a precision reference, and internal soft-start. The exposed pad (EP) of the LFCSP-8 package provides a low thermal resistance path (about 36 C/W) for the small 50 mA load it serves, ensuring reliable operation across -40C to +125C junction temperatures.
Typical applications include 4-20 mA current-loop powered field transmitters, industrial sensors, smart meters, isolated industrial interface modules, low-power analog front-end bias rails, battery-powered industrial monitors, and remote telemetry nodes. The wide VIN tolerance also suits 24V, 36V, and 48V industrial buses.
When designing with the ADP2360ACPZ-R7, size the inductor for the peak current boundary at your worst-case load and use low-ESR ceramic input/output capacitors to keep ripple below your analog front-end noise budget. The exposed pad must be soldered to a sufficiently large copper pour for proper thermal dissipation.

Typische Anwendungen
ADP2360ACPZ-R7 ist geeignet für 6 Anwendungs: 4-20 mA Current-Loop Powered Field Transmitters, Industrial Sensor Signal Conditioning Bias, Smart Metering and Utility Edge Nodes, Isolated Industrial Interface Modules, Remote Telemetry and Wireless Sensor Nodes, Battery-Powered Industrial Monitors.
4-20 mA Current-Loop Powered Field Transmitters
The ADP2360ACPZ-R7 is purpose-built for 4-20 mA current-loop-powered field transmitters where the loop supply can swing from a few volts up to 50V or more across compliance. Its 4.5V to 60V input range covers virtually every industrial loop architecture, and the DCM synchronous buck topology delivers 80%+ efficiency even with milliamps of load current, leaving enough headroom inside the 4 mA zero-signal budget to power an MCU, ADC, and HART modem. Pair it with the ADP2360's adjustable output (0.8V to VIN) to generate 3.3V rails directly from the loop. Unlike an LDO, this regulator avoids burning VIN-VOUT as heat, which is critical when total loop current is capped.
Empfohlen
Industrial Sensor Signal Conditioning Bias
In industrial analog front-end signal chains, the ADP2360ACPZ-R7 provides a clean, post-regulated bias rail from a 24V or 36V PLC backplane. Its adjustable output (0.8V-VIN) drops to 5V or 3.3V with low output ripple thanks to synchronous rectification and ceramic-cap-only BOM, ideal for op-amps, ADCs, and reference ICs that demand low-noise supplies. The wide VIN range tolerates industrial bus transients, and the 8-LFCSP-EP package keeps the solution under 50 mm^2 - critical for crowded PLC backplanes. The DCM architecture limits reverse current at no load, extending hold-up time when downstream sensors enter sleep states between scans.
Empfohlen
Smart Metering and Utility Edge Nodes
Smart electricity, water, and gas meters draw small bias currents from isolated or battery-backed sources, and the ADP2360ACPZ-R7's 50 mA continuous rating fits the typical 10-30 mA sensor-plus-MCU budget. Its 60V input tolerance suits 48V telecom-grade battery rails used in advanced metering infrastructure, while the synchronous DCM topology preserves battery life by avoiding the continuous Iq loss of an LDO at high step-down ratios. The 3x3 mm LFCSP EP footprint enables single-board meter designs that fit inside standard meter base sockets, and the wide temperature range (-40C to +125C junction) survives outdoor enclosure conditions.
Empfohlen
Isolated Industrial Interface Modules
Isolated digital interface modules (RS-485, RS-232, CAN, IO-Link) require a low-power bias rail derived from a 5V, 12V, or 24V bus, and the ADP2360ACPZ-R7 handles all of these inputs within a single design. Its synchronous buck architecture achieves >85% efficiency even at light loads, minimizing the heat dissipated inside sealed industrial housings. Combined with a digital isolator such as the ADM3251EARWZ or ADM3072EARZ, the ADP2360ACPZ-R7 forms a compact, reliable interface front-end that survives ESD, surge, and surge events on the field wiring. The exposed pad enables direct PCB heat-sinking without an external heatsink.
Empfohlen
Remote Telemetry and Wireless Sensor Nodes
Wireless sensor nodes deployed in remote locations often scavenge energy from 24V industrial rails or solar-charged battery packs, and the ADP2360ACPZ-R7's wide 4.5V-60V input eliminates the need for a pre-regulator. Its 50 mA output capability supports burst transmissions from sub-GHz or LoRa radios that draw peaks of 30-80 mA, while DCM operation prevents reverse current flow during the radio's sleep cycles. The 8-LFCSP-EP 3x3 mm footprint leaves ample PCB area for the antenna, MCU, and sensor. Across temperature, the synchronous topology delivers 80%+ efficiency, extending battery life in field installations.
Empfohlen
Battery-Powered Industrial Monitors
Portable industrial monitors - handheld gas detectors, insulation testers, and process calibrators - rely on multi-cell Li-ion or LiSOCl2 batteries that present 6V-36V across their discharge curve. The ADP2360ACPZ-R7 regulates this directly down to 3.3V or 5V for the host MCU, display, and sensor front-end, eliminating a pre-regulator stage. Synchronous DCM operation holds efficiency above 80% across the full discharge curve, extending operating time per charge. The 8-LFCSP-EP package's small footprint fits inside handheld enclosures, and the exposed pad pulls heat directly into the PCB ground pour for reliable thermal performance.

Wichtigste Unterscheidungsmerkmale
- Wide 4.5V to 60V input range handles full industrial compliance voltages (vs. ADP2360ACPZ-5.0-R7)
- Adjustable output in the same 8-LFCSP-EP footprint as fixed-voltage family members (vs. ADP2360ACPZ-3.3-R7)
- DCM synchronous topology with 80%+ efficiency at light loads (vs. ADP2360ACPZ-1.8-R7)
Designhinweise
Estimated: at VIN=24V, VOUT=3.3V, IOUT=50 mA, the ADP2360ACPZ-R7 dissipates approximately (24-3.3) * 0.05 = ~1.04 W (input-referred) with >80% efficiency. The 8-LFCSP-EP package has theta_JA around 36 C/W on a standard JEDEC 4-layer board, so junction temperature rise above ambient is roughly 37 C at full load. The exposed pad must be soldered to a PCB ground pour of at least 100 mm^2 to maintain this thermal path; otherwise, junction temperature can climb above 125 C and trigger thermal shutdown.
Place the input ceramic capacitor as close as possible to the VIN and GND pins to suppress high-frequency switching noise. Route the SW node trace as short and wide as practical to minimize parasitic inductance and radiated EMI. Keep the FB/ADJ trace away from the SW node to avoid noise coupling into the feedback loop. The exposed pad requires multiple thermal vias (typically 6-9) connecting to an internal ground plane for proper heat spreading.
Do not exceed 60V on VIN - the device has internal over-voltage protection but sustained transients above this can damage the internal MOSFETs. The RT/SS pin doubles as both a soft-start timing capacitor node and a switching frequency programming resistor connection - leaving it floating disables soft-start and may cause startup overshoot. Always use ceramic capacitors (X5R or X7R) on input and output - the regulator is optimized for low-ESR ceramics and performance is not guaranteed with tantalum or electrolytic capacitors.
