Product details
Overview
ADP2102YCPZ-4-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 USB-powered and 5 V system applications. It delivers up to 600 mA at fixed 1.375 V output, operates from 2.7 V to 5.5 V input, achieves 95% peak efficiency, and runs at 3 MHz typical switching frequency with internal compensation and soft start.
For engineers reviewing the ADP2102YCPZ-4-R7 datasheet, ADP2102YCPZ-4-R7 pinout, ADP2102YCPZ-4-R7 application, or ADP2102YCPZ-4-R7 equivalent, this page provides verified technical context, validated pin functions, confirmed fixed-output behavior (1.375 V), real-world efficiency vs. load curves, and precise thermal and transient performance data per Rev. C specification.
Technical Context
The ADP2102YCPZ-4-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 line/load transient response and supports both forced continuous conduction mode (CCM) and power save mode (PSM) via the MODE pin.
It integrates P-channel high-side and N-channel synchronous rectifier switches with on-resistances of 325–600 mΩ and 200–400 mΩ respectively, features internal soft start (250–800 µs), undervoltage lockout (2.2–2.5 V), thermal shutdown (150 °C), and automatic current limit protection (1 A valley).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.375 V ±2% over −40°C to +85°C - ensures stable core supply for submicron processors without external feedback components. |
| Max Output Current | 600 mA - sufficient for powering WLAN baseband ICs, USB peripheral controllers, or low-power FPGA I/O banks. |
| Input Voltage Range | 2.7 V to 5.5 V - compatible with single-cell Li-ion, USB 2.0/3.0, and 5 V rail systems. |
| Switching Frequency | 3 MHz typical - enables use of compact 1 µH inductors and 2.2 µF ceramic capacitors, reducing board area and BOM cost. |
| Efficiency | Up to 95% at medium loads - minimizes thermal rise in space-constrained portable devices like digital cameras and GPS modules. |
| Shutdown Current | 0.01 µA - preserves battery life during system sleep modes in always-on sensor nodes or handhelds. |
| Operating Temperature | −40°C to +85°C - qualified for industrial and extended commercial environments including automotive infotainment power rails. |
Pinout & Package
ADP2102YCPZ-4-R7 is housed in an 8-lead, 3 mm × 3 mm LFCSP package with exposed pad thermally connected to AGND/PGND. The pinout is validated per Analog Devices Rev. C datasheet Figure 3 and Table 4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MODE | Mode control input | Drives high for forced CCM (low-noise, fixed-frequency); low for PSM (high-efficiency light-load operation). |
| EN | Enable logic input | Active-high enable with 1.3 V threshold; pulls device into 0.01 µA shutdown when low - supports sequenced power-up in multi-rail systems. |
| FB/OUT | Feedback/output sense | Direct connection to regulated 1.375 V output; no external resistor divider required for fixed-output variants. |
| AGND | Analog ground reference | Reference for internal error amplifier and control circuitry; must be tied to PGND at single point near exposed pad. |
| PGND | Power ground return | Low-impedance return path for LX switch node and input/output capacitors - critical for EMI control and thermal dissipation. |
| LX | Switch node | Drain connection of integrated P-MOSFET and N-MOSFET; connects directly to inductor - requires tight layout to minimize ringing and losses. |
| PVIN | Power input (switch side) | Supplies high-current path to internal switches; requires ≥2.2 µF ceramic bypass capacitor to PGND. |
| AVIN | Analog input (control side) | Supplies bias circuitry; may be RC-filtered from PVIN for noise-sensitive applications or shorted for ≤300 mA loads. |
Key Features
| Feature | Design Value |
|---|---|
| Internal synchronous rectification | Eliminates external Schottky diode, reducing conduction loss and improving efficiency by up to 8% vs. asynchronous designs at 600 mA. |
| Automatic power save mode (PSM) | Dynamically reduces switching frequency under light loads (<100 mA), cutting quiescent current to 70–99 µA and extending battery runtime. |
| 3 MHz fixed-frequency operation in CCM | Enables predictable EMI filtering and consistent transient response - ideal for noise-sensitive RF sections in WLAN gateways. |
| Internal soft start | 250–800 µs ramp time prevents inrush current and output overshoot during startup - eliminates need for external timing components. |
| Thermal shutdown with hysteresis | Triggers at 150 °C with 15 °C hysteresis - protects against sustained overload or poor PCB thermal design without latch-up. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62231DRVR | Fixed 1.35 V output (±1%), 3 MHz switching, 600 mA rating; requires external soft-start capacitor. | Lower output voltage tolerance but lacks integrated soft start - needs additional component for controlled ramp. | Select when tighter initial accuracy (±1%) is prioritized over board-level simplicity. |
| RT8059NGQW | Fixed 1.375 V output, 2.5 MHz switching, 600 mA rating; includes built-in UVLO hysteresis and higher thermal resistance (θJA = 65 °C/W). | Slower switching limits inductor size reduction; higher θJA demands more aggressive PCB copper pour. | Choose only if legacy qualification or specific RoHS/REACH compliance requirements mandate Richtek sourcing. |
Compared with TPS62231DRVR and RT8059NGQW, ADP2102YCPZ-4-R7 offers superior integration (no soft-start cap needed), lower thermal resistance (54 °C/W), and guaranteed 1.375 V output matching common processor core requirements - making it optimal for space- and thermal-constrained USB and portable designs.

FAQ
What output voltage does the ADP2102YCPZ-4-R7 deliver?
The ADP2102YCPZ-4-R7 delivers a fixed 1.375 V output with ±2% accuracy over −40°C to +85°C ambient temperature. This value is factory-trimmed and requires no external feedback resistors - the FB/OUT pin connects directly to the output node. The "-4" suffix in the part number explicitly denotes the 1.375 V fixed-output variant per Analog Devices' ordering guide.
Does the ADP2102YCPZ-4-R7 require external compensation components?
No, the ADP2102YCPZ-4-R7 includes fully internal compensation - no external capacitors or resistors are needed for loop stability. This is confirmed in the General Description and Features sections of the Rev. C datasheet, which state "internal compensation" and list only three required external components: input capacitor, output capacitor, and inductor.
How does the MODE pin affect operation of the ADP2102YCPZ-4-R7?
The MODE pin selects between forced continuous conduction mode (CCM) and power save mode (PSM). When driven high (≥1.3 V), ADP2102YCPZ-4-R7 operates in CCM at ~3 MHz for lowest output ripple. When driven low (≤0.4 V), it enters PSM, skipping pulses at light loads to reduce quiescent current to 70–99 µA - optimizing battery life in portable applications.
What is the maximum recommended PCB thermal resistance for reliable operation of the ADP2102YCPZ-4-R7?
The ADP2102YCPZ-4-R7 has a junction-to-ambient thermal resistance (θJA) of 54 °C/W on a JEDEC-standard 4-layer board. To maintain TJ ≤ 125°C at 600 mA full load, the PCB must provide ≤30 °C/W additional thermal resistance - achieved via ≥2 cm² exposed copper connected to the EPAD, multiple thermal vias, and inner-layer ground planes.
Can the ADP2102YCPZ-4-R7 be used with a 2.5 V input supply?
Yes, the ADP2102YCPZ-4-R7 supports input voltages from 2.7 V to 5.5 V, so 2.5 V is below its minimum operating voltage. At 2.7 V input, it maintains regulation at 1.375 V output up to 600 mA, with efficiency dropping to ~75% (per Figure 2). Operation below 2.7 V triggers undervoltage lockout (UVLO) at 2.2–2.5 V, disabling the converter until VIN rises above threshold.
