Product details
Overview
ADP2102YCPZ-1.0-R7 from Analog Devices is a synchronous step-down DC-DC converter delivering up to 600 mA at fixed 1.0 V output, operating from 2.7 V–5.5 V input with 3 MHz switching frequency, 95% peak efficiency, and 1% initial output accuracy-designed for USB-powered processor core rails in portable media players and WLAN gateways.
For engineers reviewing the ADP2102YCPZ-1.0-R7 datasheet, ADP2102YCPZ-1.0-R7 pinout, ADP2102YCPZ-1.0-R7 application, or ADP2102YCPZ-1.0-R7 equivalent, this page delivers verified technical context, validated pin functions, confirmed load/line regulation specs, and real-world PSM/CCM mode trade-offs for low-voltage submicron core power design.
Technical Context
The ADP2102YCPZ-1.0-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 with minimal external components. Its valley current sensing supports stable DCM/CCM boundary operation down to 1.0 V output.
It integrates internal synchronous rectification (P-channel high-side + N-channel low-side), soft-start (250–800 µs), undervoltage lockout (2.2–2.5 V threshold), and thermal shutdown (150°C). MODE pin selects forced CCM (low noise) or automatic PSM (high light-load efficiency).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.7 V to 5.5 V - supports direct USB 3.3 V/5 V rail and Li-ion battery inputs without pre-regulation |
| Output Voltage | Fixed 1.0 V - precisely trimmed for sub-1V processor cores; ±1% initial accuracy at 25°C ensures stable logic-level compliance |
| Max Output Current | 600 mA - sufficient for ARM Cortex-A/M series cores and baseband processors in compact handheld devices |
| Switching Frequency | 3 MHz typical - enables use of 1 µH inductors and 2.2 µF ceramic capacitors, reducing solution size by >40% vs. 1 MHz converters |
| Efficiency | 95% peak - achieved at medium loads with synchronous rectification; maintains >85% down to 10 mA in PSM mode |
| Shutdown Current | 0.01 µA - ultra-low quiescent draw preserves battery life during system sleep states |
| Operating Temperature | −40°C to +85°C - qualified for industrial and extended-temperature portable applications |
Pinout & Package
ADP2102YCPZ-1.0-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 heat dissipation in space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - MODE | Mode Control Input | Drives high for forced CCM (low ripple); low for automatic PSM (high light-load efficiency) |
| 2 - EN | Enable Logic Input | Active-high enable; pulls <0.1 µA when disabled; must not be left floating |
| 3 - FB/OUT | Feedback / Output Sense | Internally tied to top of divider for fixed 1.0 V version; connects directly to output node |
| 4 - AGND | Analog Ground Reference | Reference for error amplifier and bias circuits; must connect to PGND at single point near IC |
| 5 - PGND | Power Ground Return | High-current return path for LX switch and output capacitor; ties to exposed pad |
| 6 - LX | Switch Node | Drain connection of internal P-MOSFET and N-MOSFET; drives external LC filter |
| 7 - PVIN | Power Input (Switch Side) | Supplies high-current path to internal switches; requires ≥2.2 µF ceramic bypass to PGND |
| 8 - AVIN | Power Input (Analog Side) | 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; reduces conduction loss and improves efficiency by 5–10% over asynchronous designs |
| Automatic Power Save Mode (PSM) | Dynamically skips pulses under light load (<100 mA typical), cutting quiescent current to 70–99 µA and extending battery runtime |
| 3 MHz Constant-On-Time Control | Delivers <10 µs load transient recovery and stable operation across input/temperature; avoids loop compensation design effort |
| Integrated Soft Start | 250–800 µs controlled ramp prevents inrush current and output overshoot during power-up sequences |
| Thermal & Current Protection | Includes valley current limit (~1 A), thermal shutdown (150°C), and UVLO (2.2–2.5 V) - ensures robustness in unregulated input environments |

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 |
|---|---|---|---|
| TPS62231DRYR | Fixed 1.0 V output; 3 MHz switching; 600 mA rating; but uses voltage-mode control and lacks PSM auto-transition | Requires external compensation; less optimal for wide-load-range battery apps due to higher light-load IQ (12 µA vs. 0.01 µA shutdown) | Prefer ADP2102YCPZ-1.0-R7 when ultra-low shutdown current and seamless PSM/CCM transition are required. |
| RT8059NGQW | Fixed 1.0 V; 3 MHz; 600 mA; integrated soft-start; but no MODE pin for manual CCM forcing and no valley current limit | Lacks programmable mode control - cannot guarantee low-noise CCM operation for RF-sensitive loads | Choose ADP2102YCPZ-1.0-R7 where deterministic CCM entry and robust current limiting are critical for reliability. |
Compared with TPS62231DRYR and RT8059NGQW, ADP2102YCPZ-1.0-R7 uniquely combines ultra-low shutdown current (0.01 µA), user-selectable CCM/PSM via MODE pin, and valley-current protection - making it superior for battery-critical, RF-cohabitant, and thermally constrained portable core rail applications.

FAQ
What output voltage does the ADP2102YCPZ-1.0-R7 deliver?
The ADP2102YCPZ-1.0-R7 delivers a factory-trimmed fixed output voltage of 1.0 V with ±1% initial accuracy at 25°C and ±2% over the full −40°C to +85°C temperature range. This precision enables reliable operation of sub-1V digital cores without external feedback components.
Does the ADP2102YCPZ-1.0-R7 support both forced CCM and automatic PSM modes?
Yes, the ADP2102YCPZ-1.0-R7 supports both modes via the MODE pin: driving MODE high forces continuous conduction mode (CCM) for low-noise operation, while driving MODE low enables automatic power save mode (PSM) that dynamically skips pulses under light load to minimize quiescent current.
What is the minimum number of external components required for the ADP2102YCPZ-1.0-R7?
The ADP2102YCPZ-1.0-R7 requires only three external components: one input capacitor (≥2.2 µF), one output capacitor (≥2.2 µF), and one inductor (1 µH typical). No external compensation network or feedback resistors are needed for the fixed 1.0 V version.
What protection features are integrated into the ADP2102YCPZ-1.0-R7?
The ADP2102YCPZ-1.0-R7 integrates valley current limit (~1 A), thermal shutdown (150°C with 15°C hysteresis), undervoltage lockout (2.2–2.5 V rising threshold), and internal soft start (250–800 µs). These ensure safe operation during fault conditions and startup transients.
Is the ADP2102YCPZ-1.0-R7 compatible with ceramic output capacitors?
Yes, the ADP2102YCPZ-1.0-R7 is fully optimized for ceramic output capacitors - specifically designed to operate stably with 2.2 µF X5R/X7R types. Its internal compensation and constant-on-time architecture eliminate the need for ESR-based damping, simplifying layout and improving transient response.
