Product details
Overview
ADP2102YCPZ-1.2-R7 from Analog Devices is a synchronous step-down DC-to-DC converter delivering 600 mA at fixed 1.2 V output, operating from 2.7 V to 5.5 V input with 95% peak efficiency, 3 MHz switching frequency, and 0.01 µA shutdown current-designed for USB-powered processor core rails in portable media players and WLAN gateways.
For engineers reviewing the ADP2102YCPZ-1.2-R7 datasheet, ADP2102YCPZ-1.2-R7 pinout, ADP2102YCPZ-1.2-R7 application, or ADP2102YCPZ-1.2-R7 equivalent, key selection criteria include fixed 1.2 V output accuracy (±1% at 25°C), low-duty-cycle capability for sub-1.2 V core scaling, integrated synchronous rectification, power save mode for ultra-low quiescent current, and LFCSP-8 package thermal performance.
Technical Context
The ADP2102YCPZ-1.2-R7 uses constant on-time, valley current-mode control with voltage feed-forward to maintain pseudofixed 3 MHz operation across input voltage variations while enabling fast transient response. Its architecture supports both forced continuous conduction mode (CCM) via MODE pin high and automatic power save mode (PSM) via MODE pin low.
It integrates P-channel high-side and N-channel synchronous rectifier switches with on-resistances of 325–600 mΩ and 200–400 mΩ respectively, internal soft start (250–800 µs), undervoltage lockout (2.2–2.5 V threshold), and thermal shutdown (150°C). The FB/OUT pin serves as output sense for fixed-voltage variants, eliminating external feedback resistors.
Key Specifications

Pinout & Package
ADP2102YCPZ-1.2-R7 is housed in an 8-lead, 3 mm × 3 mm LFCSP package with exposed pad thermally connected to PCB ground plane. Pin 1 is MODE; Pin 2 is EN; Pin 3 is FB/OUT; Pin 4 is AGND; Pin 5 is PGND; Pin 6 is LX; Pin 7 is PVIN; Pin 8 is AVIN.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MODE | Mode control input | Drives high for forced CCM (low-noise, fixed-frequency); drives low for PSM (high-efficiency light-load operation). |
| EN | Enable logic input | Active-high; enables device when pulled ≥1.3 V; reduces supply current to 0.01 µA when pulled ≤0.4 V. |
| FB/OUT | Fixed-output voltage sense | Internally connected to top of feedback divider; must be connected directly to output node for regulation. |
| AGND / PGND | Analog & power ground | Separate ground pins require single-point connection near device; exposed pad electrically tied to AGND. |
| LX | Switch node | Drain of integrated P-MOSFET and source of N-MOSFET; connects to inductor and output filter capacitor. |
| PVIN / AVIN | Power and analog supply inputs | PVIN supplies power switch; AVIN powers control circuitry-can be RC-filtered or bypassed per load current. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated synchronous rectification | Eliminates external Schottky diode, reducing conduction losses and PCB footprint in 600 mA buck designs. |
| Automatic power save mode (PSM) | Reduces switching frequency under light loads, cutting quiescent current to 70–99 µA and extending battery runtime. |
| Internal compensation & soft start | Removes need for external compensation network; 250–800 µs soft-start prevents inrush current and output overshoot. |
| Low duty cycle capability | Supports 1.2 V output from 5 V input (24% duty cycle), enabling efficient core rail generation in USB-powered systems. |
| Thermal shutdown & current limit | Protects against sustained overload or poor PCB thermal design; triggers at 150°C junction temperature with 15°C hysteresis. |

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 |
|---|---|---|---|
| TPS62231DRYT | Fixed 1.2 V output, 600 mA, 3.6 MHz, 2.05–6.0 V input; smaller 2 × 2 mm DSBGA but no MODE pin for CCM/PSM selection. | Lacks configurable mode control; operates only in auto-PSM, limiting low-noise CCM use in sensitive RF sections. | Choose when board space is critical and CCM is not required; verify thermal performance with 54°C/W θJA vs. ADP2102YCPZ-1.2-R7's 54°C/W. |
| RT8059NGQW | Fixed 1.2 V, 600 mA, 3 MHz, 2.5–5.5 V input; includes enable polarity inversion and higher 2.5 µA shutdown current. | Higher shutdown current reduces deep-sleep battery savings; lacks valley current sensing for lowest-duty-cycle stability. | Prefer when enable logic polarity matching is needed; avoid where sub-100 µA quiescent current is mandatory for multi-week standby. |

FAQ
What is the output voltage tolerance of the ADP2102YCPZ-1.2-R7 over temperature?
The ADP2102YCPZ-1.2-R7 provides ±2% output voltage accuracy across the full −40°C to +85°C operating ambient temperature range at zero load, verified per Table 1 in the Rev. C datasheet. At 25°C, initial accuracy is tighter at ±1%, supporting precise core voltage requirements for modern low-voltage processors.
Does the ADP2102YCPZ-1.2-R7 require external feedback resistors?
No, the ADP2102YCPZ-1.2-R7 does not require external feedback resistors. As a fixed 1.2 V output variant, its FB/OUT pin is internally connected to the top of the voltage divider; it must be connected directly to the output node for regulation, eliminating component count and layout sensitivity.
How does the MODE pin affect efficiency and noise in the ADP2102YCPZ-1.2-R7?
When MODE is high, ADP2102YCPZ-1.2-R7 operates in forced CCM at ~3 MHz, minimizing output voltage ripple (<10 mVpp) but reducing light-load efficiency. When MODE is low, it enters PSM, skipping pulses to achieve 70–99 µA quiescent current-improving battery life at the cost of higher low-frequency ripple.
What is the minimum off-time specification for the ADP2102YCPZ-1.2-R7?
The ADP2102YCPZ-1.2-R7 has a guaranteed minimum off-time of 100 ns, as specified in Table 1 under "LX Minimum Off Time." This parameter enables stable operation at very low duty cycles (e.g., 1.2 V from 5 V ≈ 24%), critical for powering sub-1.2 V processor cores without pulse-skipping instability.
Can the ADP2102YCPZ-1.2-R7 be used with a 1 µH inductor and 2.2 µF output capacitor?
Yes-the ADP2102YCPZ-1.2-R7 is explicitly characterized with a 1 µH inductor and 2.2 µF ceramic output capacitor in its Typical Application Circuit (Figure 1) and Efficiency plots (Figures 4–10). This combination achieves optimal transient response and 95% peak efficiency while meeting EMI and size targets for portable designs.
