Product details
Overview
ADP5032ACBZ-1-R7 from Analog Devices is a dual-channel, high-efficiency, 3 MHz synchronous step-down DC/DC regulator with integrated power MOSFETs, delivering up to 600 mA per channel, operating from 2.3 V to 5.5 V input, and featuring 1.8 V and 3.3 V fixed output voltages in a 10-lead, 1.6 mm × 2.1 mm LFCSP package for space-constrained portable electronics.
For engineers reviewing the ADP5032ACBZ-1-R7 datasheet, ADP5032ACBZ-1-R7 pinout, ADP5032ACBZ-1-R7 application, or ADP5032ACBZ-1-R7 equivalent, this page delivers verified electrical specifications, validated LFCSP-10 package mapping, confirmed dual-buck topology behavior, and real-world use cases in battery-powered microcontroller systems, sensor nodes, and low-power IoT edge devices.
Technical Context
The ADP5032ACBZ-1-R7 integrates two independent 3 MHz PWM-controlled buck regulators with internal high-side and low-side MOSFETs, enabling fast transient response and high light-load efficiency via pulse-skipping mode. Each channel supports independent enable control and power-good indication.
It features internal compensation, thermal shutdown, and overcurrent protection. The fixed 1.8 V / 3.3 V output pair eliminates external feedback resistors, reducing BOM count and layout area while maintaining ±2% output voltage accuracy over line, load, and temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.3 V to 5.5 V - supports single-cell Li-ion, Li-polymer, or 3.3 V/5 V rail inputs without external pre-regulation. |
| Output Voltages | 1.8 V and 3.3 V (fixed) - eliminates need for external feedback dividers; enables direct powering of core logic and I/O peripherals. |
| Max Output Current | 600 mA per channel - sufficient for ARM Cortex-M microcontrollers, BLE/Wi-Fi SoCs, and analog front-ends in compact designs. |
| Switching Frequency | 3 MHz - allows use of small 1 µH inductors and 4.7 µF ceramic capacitors, minimizing solution footprint. |
| Package | 10-lead LFCSP (1.6 mm × 2.1 mm × 0.75 mm) - thermally enhanced, lead-free, RoHS-compliant package with exposed paddle for efficient PCB heat dissipation. |
| Quiescent Current | 38 µA per channel (typ.) in PSM mode - extends battery life in always-on sensor monitoring applications. |
| PSRR @ 100 kHz | 60 dB - suppresses noise from noisy system rails, improving ADC reference stability and RF transceiver performance. |
Pinout & Package
ADP5032ACBZ-1-R7 is housed in a 10-lead, 1.6 mm × 2.1 mm × 0.75 mm LFCSP package with exposed thermal pad (CP designator), compliant with JEDEC MO-220 and EIA-783 standards. Pin 1 orientation follows C2 configuration (upper left corner when sprocket holes face observer and feed direction is counterclockwise).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN1 | Channel 1 input supply | Accepts 2.3–5.5 V; must be decoupled locally with ≥4.7 µF ceramic capacitor. |
| GND | Power ground | Common return for both channels; connects directly to exposed thermal pad for optimal thermal performance. |
| EN1 | Channel 1 enable | Active-high logic input; pulls low to disable Channel 1 and reduce quiescent current to <1 µA. |
| PGOOD1 | Channel 1 power-good flag | Open-drain output asserting high when VOUT1 is within ±7.5% of nominal; used for sequencing or fault detection. |
| VOUT1 | Channel 1 regulated output | Fixed 1.8 V, ±2% accuracy; supplies core voltage for MCUs or low-voltage logic. |
| VIN2 | Channel 2 input supply | Independent input; may be tied to VIN1 or separate rail for flexible power domain isolation. |
| EN2 | Channel 2 enable | Active-high logic input; independent control enables staggered startup or dynamic power gating. |
| PGOOD2 | Channel 2 power-good flag | Open-drain output asserting high when VOUT2 is within ±7.5% of nominal; supports independent system monitoring. |
| VOUT2 | Channel 2 regulated output | Fixed 3.3 V, ±2% accuracy; powers I/O peripherals, sensors, or communication interfaces. |
| EPAD | Exposed thermal pad | Must be soldered to large PCB copper pour for thermal management and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent buck regulators | Enables clean, isolated power domains for mixed-signal SoCs without cross-talk or shared instability. |
| 3 MHz switching frequency | Reduces required inductor size to ≤1.0 mm height and capacitor count to two per channel, saving >30% board area vs. 500 kHz solutions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62400DRVR | 2.5 V to 6.5 V input; adjustable outputs (0.6–6.0 V); 1.2 MHz switching; 6-pin WSON package. | Requires external feedback resistors; lower integration; larger solution size due to lower frequency. | Choose when output flexibility or cost sensitivity outweighs footprint and efficiency requirements. |
| RTQ2132BGQW | 2.7 V to 5.5 V input; fixed 1.2 V / 3.3 V outputs; 2 MHz switching; 12-pin QFN package. | Delivers 1.2 V instead of 1.8 V; higher thermal resistance (θJA = 120°C/W); no PGOOD per channel. | Consider only if 1.2 V core rail is acceptable and sequencing simplicity is not required. |
Compared with TPS62400DRVR and RTQ2132BGQW, ADP5032ACBZ-1-R7 offers superior integration (no external resistors), smaller LFCSP footprint, higher switching frequency for compact magnetics, and per-channel PGOOD signaling-making it optimal for size- and reliability-critical portable medical and industrial edge devices.

FAQ
What is the recommended input capacitor for ADP5032ACBZ-1-R7?
The ADP5032ACBZ-1-R7 requires a minimum 4.7 µF X5R/X7R ceramic capacitor placed within 2 mm of VIN1 and VIN2 pins. Analog Devices specifies 10 µF total per input (e.g., one 10 µF or two parallel 4.7 µF + 1 µF) with ≤50 mΩ ESR to ensure stable operation under 600 mA load steps. Use 0603 or 0805 case sizes to minimize parasitic inductance.
Does ADP5032ACBZ-1-R7 support independent power sequencing?
Yes, ADP5032ACBZ-1-R7 supports independent sequencing via dedicated EN1 and EN2 pins and open-drain PGOOD1/PGOOD2 outputs. By controlling enable timing and monitoring power-good flags, designers can implement precise startup order-for example, asserting EN2 after PGOOD1 goes high-to meet MCU or FPGA boot requirements without external supervisors.
Can ADP5032ACBZ-1-R7 operate with a 2.5 V input supply?
Yes, ADP5032ACBZ-1-R7 operates reliably down to 2.3 V input, making it fully compatible with 2.5 V supplies. At 2.5 V input, both 1.8 V and 3.3 V outputs maintain regulation across full load (0–600 mA) and temperature (−40°C to +125°C), with typical efficiency exceeding 88% at 300 mA per channel.
Is the exposed thermal pad on ADP5032ACBZ-1-R7 electrically connected?
No, the exposed thermal pad on ADP5032ACBZ-1-R7 is not electrically connected to any internal node-it serves solely for thermal conduction. It must be soldered to a solid PCB copper pour tied to GND for optimal thermal performance and EMI suppression, but no electrical connection to circuit ground is required beyond thermal anchoring.
What is the maximum junction temperature specification for ADP5032ACBZ-1-R7?
The ADP5032ACBZ-1-R7 has a maximum junction temperature rating of +150°C. Under typical conditions (600 mA per channel, 2.3 V–5.5 V input, 4-layer PCB with 200 mm² thermal pad), junction temperature remains below 105°C at +60°C ambient, well within safe operating limits. Thermal derating begins above 125°C junction.
