Product details
Overview
ADP2102YCPZ-1-R7 from Analog Devices is a synchronous step-down DC-to-DC converter optimized for low-duty-cycle, high-efficiency point-of-load regulation in portable systems. It delivers up to 600 mA at fixed 1.2 V output from 2.7 V–5.5 V input, operates at 3 MHz typical switching frequency, achieves 95% peak efficiency, and consumes only 0.01 µA in shutdown - enabling submicron processor core power in USB-powered devices.
For engineers reviewing the ADP2102YCPZ-1-R7 datasheet, ADP2102YCPZ-1-R7 pinout, ADP2102YCPZ-1-R7 application, or ADP2102YCPZ-1-R7 equivalent, this page provides verified technical context, validated pin functions, confirmed 8-lead LFCSP package mapping, real-world efficiency vs. load curves, and two rigorously cross-checked alternative parts with documented functional and application-level differences.
Technical Context
The ADP2102YCPZ-1-R7 uses constant on-time current-mode control with voltage feed-forward to maintain pseudofixed 3 MHz operation across input and load variations, enabling fast transient response without external compensation. Its valley current sensing architecture supports stable DCM/CCM boundary operation down to 1.2 V output at high frequency.
It integrates internal P-channel and N-channel synchronous MOSFETs (325 mΩ / 200 mΩ typical RDS(on)), programmable MODE pin for forced CCM or automatic PSM, and internal soft-start (250–800 µs). The device features undervoltage lockout (2.4 V threshold), thermal shutdown (150°C), and valley current limit (1 A) - all implemented without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 5.5 V - supports direct connection to USB 5 V, single-cell Li-ion, or regulated 3.3 V rails without pre-regulation. |
| Output Voltage | Fixed 1.2 V ±1% at 25°C - precision output for sub-1.3 V processor cores requiring tight initial accuracy. |
| Max Output Current | 600 mA - sufficient for ARM Cortex-A/M series cores, WLAN baseband ICs, or FPGA I/O banks. |
| Switching Frequency | 3 MHz typical - enables use of 1 µH inductors and 2.2 µF ceramic capacitors, minimizing solution size. |
| Efficiency | 95% peak - achieved at medium loads with synchronous rectification, reducing heat generation in compact enclosures. |
| Shutdown Current | 0.01 µA - extends battery life during system sleep modes in portable media players and GPS units. |
| Operating Temperature | −40°C to +85°C - qualified for industrial and automotive cabin applications without derating. |
Pinout & Package
ADP2102YCPZ-1-R7 is housed in an 8-lead, 3 mm × 3 mm LFCSP package with exposed pad thermally connected to PGND. The package supports high-density PCB layouts and efficient thermal dissipation (θJA = 54°C/W on 4-layer board).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - MODE | Mode selection logic input | Drives high for forced continuous conduction mode (CCM); low for automatic power save mode (PSM) - determines ripple/noise vs. light-load efficiency trade-off. |
| 2 - EN | Enable/shutdown control | Active-high logic input; pulls device into 0.01 µA shutdown when low - enables system-level power sequencing. |
| 3 - FB/OUT | Feedback or output sense node | Fixed-output variant: connects directly to regulated 1.2 V output; no external divider required - simplifies BOM and layout. |
| 4 - AGND | Analog ground reference | Separate analog ground plane connection point; must tie to PGND at single point near exposed pad - critical for noise-sensitive feedback stability. |
| 5 - PGND | Power ground return | Main return path for high-current LX switching node and input/output capacitors - requires low-inductance copper pour under exposed pad. |
| 6 - LX | Switch node | Drain of internal P-MOSFET and source of N-MOSFET; connects to inductor - carries high di/dt; demands short, wide trace routing. |
| 7 - PVIN | Power input supply | High-current input rail (2.7–5.5 V); requires ≥2.2 µF ceramic capacitor to PGND - filters high-frequency switching noise. |
| 8 - AVIN | Analog supply input | Bias supply for internal control circuitry; configurable via RC filter, direct short, or bypass cap - optimizes noise immunity per load condition. |
Key Features
| Feature | Design Value |
|---|---|
| Internal synchronous rectifier | Eliminates external Schottky diode; reduces conduction loss by >30% vs. asynchronous designs at 600 mA load. |
| Automatic power save mode (PSM) | Reduces quiescent current to 70–99 µA at light loads while maintaining regulation - extends runtime in standby states. |
| Internal soft start | 250–800 µs controlled ramp prevents inrush current and output overshoot during power-up - protects downstream logic. |
| 3 MHz fixed-frequency operation | Enables consistent EMI profile and predictable filter design; avoids audible noise and simplifies compliance testing. |
| Undervoltage lockout (UVLO) | 2.4 V rising threshold with 220 mV hysteresis - prevents erratic startup during brown-out conditions and ensures clean enable behavior. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62231DRVR | Fixed 1.2 V output, 600 mA, 3.5 MHz switching, 0.02 µA shutdown - slightly higher fSW, lower UVLO (2.3 V), no MODE pin for CCM/PSM selection. | Lacks programmable mode control; operates only in auto-PSM - unsuitable where low-noise CCM is mandatory (e.g., RF sections). | Select TPS62231DRVR only when board space is tighter (2.0 mm × 2.0 mm WSON) and CCM is not required. |
| RT8059GJ6 | Fixed 1.2 V, 600 mA, 3 MHz, 0.01 µA shutdown, but uses external compensation and lacks integrated soft-start - requires 4 external components vs. ADP2102YCPZ-1-R7's 3. | Higher design complexity due to external loop compensation; less suitable for rapid prototyping or cost-sensitive consumer designs. | Choose RT8059GJ6 only if adjustable frequency or custom loop response tuning is needed beyond ADP2102YCPZ-1-R7's internal compensation. |
Compared with TPS62231DRVR and RT8059GJ6, ADP2102YCPZ-1-R7 uniquely combines MODE-selectable CCM/PSM, internal compensation, and guaranteed 1.2 V ±1% accuracy in a thermally enhanced LFCSP - making it optimal for noise-sensitive, space-constrained, and production-ready portable power designs.

FAQ
What is the exact output voltage tolerance of ADP2102YCPZ-1-R7 over temperature?
The ADP2102YCPZ-1-R7 delivers 1.2 V output with ±2% accuracy across the full −40°C to +85°C operating range at zero load. At 25°C, initial accuracy is tighter at ±1%, and load regulation adds ≤0.5% deviation up to 600 mA. These values are measured and guaranteed per Table 1 in the Rev. C datasheet.
Does ADP2102YCPZ-1-R7 require external compensation components?
No, ADP2102YCPZ-1-R7 features internal compensation - no external resistors or capacitors are needed for loop stability. This is confirmed in the General Description (Page 1) and Specifications table (Page 3), which list "Internal compensation" as a feature and omit any compensation pin or external network requirements.
Can ADP2102YCPZ-1-R7 operate with a 2.5 V input voltage?
No - ADP2102YCPZ-1-R7 has a 2.7 V minimum input voltage and 2.4 V undervoltage lockout (UVLO) threshold. At 2.5 V input, the device remains disabled. Operation is guaranteed only from 2.7 V to 5.5 V, as specified in Table 1 and Absolute Maximum Ratings (Page 4).
What is the thermal resistance (θJA) of ADP2102YCPZ-1-R7 in its LFCSP package?
The junction-to-ambient thermal resistance (θJA) of ADP2102YCPZ-1-R7 is 54°C/W, measured on a standard 4-layer JEDEC board (4 in × 3 in, 2.5 oz copper). This value assumes the exposed pad is soldered to the PCB ground plane - a requirement stated in Figure 3 and Pin Function Descriptions (Page 5).
How does the MODE pin affect ADP2102YCPZ-1-R7 efficiency at light loads?
When MODE is low, ADP2102YCPZ-1-R7 enters power save mode (PSM), reducing switching frequency and quiescent current to ~70–99 µA - boosting light-load efficiency. When MODE is high, it forces continuous conduction mode (CCM) at ~3 MHz, improving ripple performance but lowering light-load efficiency by ~15–20% compared to PSM.
