Product details
Overview
ADP2102YCPZ-0.8-R7 from Analog Devices is a synchronous step-down DC-to-DC converter optimized for low-duty-cycle, high-efficiency power delivery in space-constrained portable systems. It operates from 2.7 V to 5.5 V input, delivers up to 600 mA at fixed 0.8 V output (per suffix -0.8), achieves 95% peak efficiency, and switches at 3 MHz typical frequency-enabling use of 1 µH inductors and 2.2 µF ceramic capacitors in USB-powered processor core applications.
For engineers reviewing the ADP2102YCPZ-0.8-R7 datasheet, ADP2102YCPZ-0.8-R7 pinout, ADP2102YCPZ-0.8-R7 application, or ADP2102YCPZ-0.8-R7 equivalent, key selection criteria include its fixed 0.8 V output voltage, 3 MHz switching frequency, internal synchronous rectification, 0.01 µA shutdown current, and LFCSP-8 (3 mm × 3 mm) package with exposed thermal pad.
Technical Context
The ADP2102YCPZ-0.8-R7 implements constant on-time, valley current-mode control with voltage feed-forward to maintain pseudofixed 3 MHz operation across input and load variations. Its architecture enables fast transient response and stable regulation down to sub-1 V outputs without minimum on-time limitations.
It integrates dual MOSFET power switches (P-channel high-side, N-channel synchronous rectifier), internal soft start (250–800 µs), undervoltage lockout (2.2–2.5 V threshold), thermal shutdown (150°C), and automatic transition between discontinuous conduction mode (DCM) at light loads and forced continuous conduction mode (CCM) when MODE = high.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 0.8 V ±2% over −40°C to +85°C - matches submicron processor core rail requirements directly. |
| Input Voltage Range | 2.7 V to 5.5 V - supports single-cell Li-ion, USB 5 V, and regulated 3.3 V/5 V system rails. |
| Max Output Current | 600 mA - sufficient for low-power ARM Cortex-M cores, WLAN baseband ICs, and sensor hubs. |
| Switching Frequency | 3 MHz typical - enables compact 1 µH inductors and reduces EMI fundamental frequency above sensitive bands. |
| Efficiency | Up to 95% at medium load - minimizes thermal rise in sealed portable enclosures. |
| Shutdown Current | 0.01 µA - preserves battery life during deep sleep in always-on IoT endpoints. |
| Package | 8-lead LFCSP (3 mm × 3 mm, 0.5 mm height) with exposed thermal pad - provides low θJA (54°C/W) and PCB-area efficiency. |
Pinout & Package
ADP2102YCPZ-0.8-R7 uses an 8-lead Lead Frame Chip Scale Package (LFCSP) with 0.5 mm pitch and thermally enhanced exposed pad soldered to PCB ground plane. Pin 1 is MODE; pin numbering follows standard top-view counterclockwise orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - MODE | Mode control input | Drives high for forced CCM (low noise); low for PSM (high light-load efficiency). |
| 2 - EN | Enable logic input | Active-high enable with 1.3 V threshold; pulls device into 0.01 µA shutdown when low. |
| 3 - FB/OUT | Feedback or output sense node | Internally connected to top of divider for fixed 0.8 V output; no external resistor required. |
| 4 - AGND | Analog ground reference | Must tie to PGND at single point near IC; electrically common with exposed pad. |
| 5 - PGND | Power ground return | Low-impedance return path for LX switch current; separate from AGND except at star point. |
| 6 - LX | Switch node | Drain of P-channel high-side and source of N-channel synchronous rectifier; connects to inductor. |
| 7 - PVIN | Main power input | Supplies high-current path to switches; requires ≥2.2 µF ceramic capacitor to PGND. |
| 8 - AVIN | Analog supply input | Bias supply for control circuitry; configurable with RC filter or bypass cap depending on load. |
Key Features
| Feature | Design Value |
|---|---|
| Internal synchronous rectification | Eliminates external Schottky diode, reducing BOM count and improving efficiency by 5–10% vs. asynchronous designs. |
| Automatic power save mode (PSM) | Reduces quiescent current to 70–99 µA at light loads while maintaining regulation via pulse-skipping DCM. |
| 3 MHz constant on-time control | Delivers <10 µs load transient recovery and enables ultra-small passive filtering without loop compensation. |
| Integrated soft start | 250–800 µs controlled ramp prevents inrush current and output overshoot during power-up. |
| Thermal and current protection | Valley current limit (~1 A) and thermal shutdown (150°C, 15°C hysteresis) ensure robust operation under fault conditions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar synchronous buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62231DRYT | Fixed 0.8 V output; 3 MHz switching; 600 mA rating; 2.05 V to 6.5 V input range - wider VIN but higher quiescent current (12 µA shutdown). | Supports higher input voltages (up to 6.5 V) but lacks integrated soft start timing control. | Choose TPS62231DRYT if system input exceeds 5.5 V or requires tighter input UVLO hysteresis. |
| RT8059GJ6 | Fixed 0.8 V output; 3 MHz switching; 600 mA rating; 2.5 V to 5.5 V input; 0.5 µA shutdown - lower shutdown current but no MODE pin for CCM/PSM selection. | Offers lower shutdown current but lacks user-selectable conduction mode, limiting noise-performance trade-off flexibility. | Choose RT8059GJ6 where minimal standby leakage dominates design priority and fixed PSM operation is acceptable. |
Compared with TPS62231DRYT and RT8059GJ6, ADP2102YCPZ-0.8-R7 uniquely combines 0.01 µA shutdown, MODE-selectable CCM/PSM, and internal compensation in a 3 mm × 3 mm LFCSP-making it optimal for space- and efficiency-critical USB-powered embedded systems requiring both low-noise and ultra-low-power modes.

FAQ
What is the output voltage tolerance of the ADP2102YCPZ-0.8-R7 over temperature and load?
The ADP2102YCPZ-0.8-R7 guarantees ±2% output voltage accuracy across −40°C to +85°C ambient temperature and full 0–600 mA load range. At 25°C and zero load, initial accuracy is tighter at ±1%. This is achieved via laser-trimmed internal feedback resistors and temperature-compensated bandgap reference, ensuring reliable core rail stability in mobile SoC applications.
Does the ADP2102YCPZ-0.8-R7 require external compensation components?
No, the ADP2102YCPZ-0.8-R7 features fully internal compensation. Its constant on-time control architecture eliminates the need for external loop compensation networks-reducing design complexity, PCB area, and component count. Only three external passive components (input cap, inductor, output cap) are required for basic operation.
How does the MODE pin affect efficiency and noise performance in the ADP2102YCPZ-0.8-R7?
When MODE is pulled high, ADP2102YCPZ-0.8-R7 operates in forced continuous conduction mode (CCM) at ~3 MHz, minimizing output voltage ripple (<10 mVpp) but reducing light-load efficiency. When MODE is low, it enters power save mode (PSM), skipping pulses to achieve 70–99 µA quiescent current-ideal for battery longevity but with higher ripple in DCM.
What thermal management considerations apply to the ADP2102YCPZ-0.8-R7 in high-current operation?
The ADP2102YCPZ-0.8-R7 has a junction-to-ambient thermal resistance (θJA) of 54°C/W on a 4-layer JEDEC board. At 600 mA and 5.5 V input, power dissipation reaches ~0.3 W; this yields ~16°C rise above ambient. To maintain safe operation, the exposed pad must be soldered to a ≥1 cm² internal or bottom-side copper pour connected to GND.
Can the ADP2102YCPZ-0.8-R7 be used with input voltages below 2.7 V?
No-the absolute minimum input voltage for functional operation is 2.7 V, and undervoltage lockout engages below 2.2 V (rising). Operation below 2.7 V violates the specified input range and may cause regulation loss, erratic switching, or failure to start. For sub-2.7 V inputs, consider the ADP211x or ADP230x families instead.
