Product details
Overview
ADP2102YCPZ-1.5-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 a fixed 1.5 V output from a 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-1.5-R7 datasheet, ADP2102YCPZ-1.5-R7 pinout, ADP2102YCPZ-1.5-R7 application, or ADP2102YCPZ-1.5-R7 equivalent, key selection criteria include its fixed 1.5 V output, 3 MHz operation enabling 1 µH inductors, internal synchronous rectification, power save mode (PSM) for ultra-low-light-load quiescent current, and 8-lead 3 mm × 3 mm LFCSP package with exposed thermal pad.
Technical Context
The ADP2102YCPZ-1.5-R7 uses constant on-time, valley current-mode control with voltage feed-forward to maintain pseudofixed 3 MHz switching across line and load variations while delivering fast transient response. Its dual-mode operation - forced continuous conduction mode (CCM) when MODE = high and power save mode (PSM) when MODE = low - enables trade-offs between ripple performance and light-load efficiency.
Internal synchronous rectification integrates both P-channel high-side and N-channel low-side MOSFETs (RDS(on) = 325 mΩ / 200 mΩ typ), eliminating external diode losses. The device includes undervoltage lockout (2.4 V threshold), thermal shutdown (150°C), valley current limit (1 A), and internal soft start (250–800 µs).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±2% over −40°C to +85°C - eliminates external feedback resistors and ensures stable core rail for digital baseband ICs. |
| Max Output Current | 600 mA - supports single-core ARM Cortex-M or low-power FPGA I/O banks without derating at 85°C ambient. |
| Switching Frequency | 3 MHz typical - enables use of compact 1 µH shielded inductors and 2.2 µF ceramic output capacitors, reducing board area by >40% vs. 1 MHz converters. |
| Efficiency | 95% peak at 3.6 VIN/1.5 VOUT/300 mA - minimizes thermal rise in sealed handheld enclosures; maintains >80% down to 10 mA in PSM mode. |
| Shutdown Current | 0.01 µA - extends battery shelf life in always-on sensor nodes or standby circuits requiring <1 µA system leakage. |
| Input Voltage Range | 2.7 V to 5.5 V - compatible with single-cell Li-ion (2.7–4.2 V), USB 5 V, and regulated 3.3 V rails without intermediate LDOs. |
| Package | 8-lead 3 mm × 3 mm LFCSP with exposed thermal pad - provides 54°C/W θJA on 4-layer PCB, enabling 0.74 W max power dissipation without heatsink. |
Pinout & Package
ADP2102YCPZ-1.5-R7 is housed in an 8-lead, 3 mm × 3 mm lead frame chip scale package (LFCSP) with exposed thermal pad electrically connected to AGND. The package requires soldering the exposed pad to a dedicated ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - MODE | Mode control input | Drives high for forced CCM (low-noise, fixed 3 MHz); drives low for PSM (high-efficiency light-load operation with pulse-skipping). |
| 2 - EN | Enable logic input | Active-high enable with 1.3 V threshold; pulls device into 0.01 µA shutdown when low; must not be left floating. |
| 3 - FB/OUT | Feedback or output sense node | For fixed-output variants like ADP2102YCPZ-1.5-R7, this pin connects directly to output rail; internal resistor divider sets 1.5 V regulation. |
| 4 - AGND | Analog ground reference | Reference for error amplifier and internal circuitry; must connect to PGND at single point near IC, and tie to exposed pad. |
| 5 - PGND | Power ground return | Low-impedance return path for LX switch current and output capacitor; separate from AGND but joined at single star point. |
| 6 - LX | Switch node | Drain of internal P-MOSFET and source of N-MOSFET; connects to inductor; requires tight layout to minimize EMI and ringing. |
| 7 - PVIN | Power input supply | Main input for power switches; requires ≥2.2 µF ceramic bypass capacitor to PGND; handles full 600 mA pulsed current. |
| 8 - AVIN | Analog supply input | Bias supply for control circuitry; can be RC-filtered from PVIN (10 Ω + 0.1 µF) for noise-sensitive applications or bypassed with 0.01 µF. |
Key Features
| Feature | Design Value |
|---|---|
| Internal synchronous rectification | Eliminates external Schottky diode, reduces conduction loss by >30%, and improves full-load efficiency to 95% without thermal penalty. |
| Power save mode (PSM) | Reduces quiescent current to 70–99 µA at no load and dynamically skips pulses below ~100 mA, extending battery runtime in sleep states. |
| 3 MHz constant on-time control | Delivers <10 µs load transient recovery with 1 µH inductor, enabling stable 1.5 V core rail for burst-mode processors and RF transceivers. |
| Integrated soft start | 250–800 µs internal ramp prevents inrush current and output overshoot during power-up, eliminating need for external timing components. |
| Thermal and current protection | Auto-recovering thermal shutdown (150°C) and cycle-by-cycle valley current limit (1 A) protect against overload and PCB hotspots. |

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 1.5 V output, 600 mA, 3.5 MHz, 2.05–6.0 V input; requires external soft start capacitor; no MODE pin for CCM/PSM selection. | Lacks programmable mode control - defaults to automatic PFM/PWM transition; less flexible for noise-sensitive audio designs. | Choose when board space is critical (1.5 mm × 1.5 mm DSBGA) and CCM forcing is unnecessary. |
| RT8059GJ6 | Fixed 1.5 V, 600 mA, 3 MHz, 2.5–5.5 V input; integrated boot capacitor; no valley current limit; thermal shutdown only. | No valley current sensing - reduced short-circuit robustness; lacks MODE pin and precise UVLO hysteresis. | Choose for cost-sensitive consumer applications where full industrial-grade protection is not required. |
Compared with TPS62231DRYR and RT8059GJ6, the ADP2102YCPZ-1.5-R7 offers superior design flexibility via independent MODE and EN pins, tighter output accuracy (±2% vs. ±3%), and comprehensive protection (valley current limit + UVLO + thermal shutdown), making it preferred for mission-critical portable embedded systems.

FAQ
What is the output voltage tolerance of the ADP2102YCPZ-1.5-R7 over temperature?
The ADP2102YCPZ-1.5-R7 guarantees ±2% initial output voltage accuracy over the full −40°C to +85°C operating temperature range. At 25°C, the tolerance tightens to ±1%. This is achieved via laser-trimmed internal feedback resistors and process-compensated bandgap reference, ensuring stable 1.5 V core rail for sensitive digital loads without external calibration.
Does the ADP2102YCPZ-1.5-R7 require external compensation components?
No, the ADP2102YCPZ-1.5-R7 features fully internal compensation. Its constant on-time control architecture with voltage feed-forward eliminates the need for external compensation networks, reducing BOM count and layout complexity. Only three external passive components - input capacitor, output capacitor, and inductor - are required for full operation.
How does the MODE pin affect efficiency and noise in the ADP2102YCPZ-1.5-R7?
When MODE = low, the ADP2102YCPZ-1.5-R7 enters power save mode (PSM), skipping pulses at light loads to achieve 70–99 µA quiescent current and >80% efficiency down to 10 mA. When MODE = high, it forces continuous conduction mode (CCM) at ~3 MHz, minimizing output voltage ripple and EMI but reducing light-load efficiency. This dual-mode capability lets designers optimize for either battery life or signal integrity.
Can the ADP2102YCPZ-1.5-R7 operate from a 2.7 V input while delivering 600 mA at 1.5 V?
Yes, the ADP2102YCPZ-1.5-R7 is fully specified to deliver 600 mA at 1.5 V output with 2.7 V input. Its low-duty-cycle capability and low RDS(on) switches (325 mΩ P-MOS, 200 mΩ N-MOS) ensure sufficient headroom and thermal margin. Efficiency remains >75% under these conditions, and thermal shutdown activates only if PCB thermal resistance exceeds design limits.
What is the recommended PCB layout practice for the exposed thermal pad of the ADP2102YCPZ-1.5-R7?
The exposed pad of the ADP2102YCPZ-1.5-R7 must be soldered to a solid copper ground plane using ≥4 thermal vias (0.3 mm diameter) placed within the pad footprint. These vias should connect to inner-layer ground planes to maximize heat dissipation. The pad is electrically tied to AGND, so improper grounding causes instability or thermal shutdown - verify continuity and low-impedance connection during assembly validation.
