Product details
Overview
ADP2230ACPZ-R7 from Analog Devices is a dual-channel, synchronous step-down DC/DC regulator delivering up to 800 mA per channel with fixed or adjustable outputs (e.g., 1.2 V/1.8 V), operating from 2.3 V to 6.5 V input, and achieving up to 94% efficiency in portable power management systems.
For engineers reviewing the ADP2230ACPZ-R7 datasheet, ADP2230ACPZ-R7 pinout, ADP2230ACPZ-R7 application, or ADP2230ACPZ-R7 equivalent, key selection criteria include dual-output phase-shifted operation, 15 µA quiescent current in PSM mode, 2 MHz PWM/PSM auto-transitioning, precision enable thresholds, and integrated quick output discharge for battery-powered instrumentation and mobile devices.
Technical Context
The ADP2230ACPZ-R7 implements a proprietary high-speed current-mode PWM control architecture with internal slope compensation, enabling excellent transient response and stability across load and line variations. Each buck channel features independent precision enable inputs (EN1/EN2), 180° out-of-phase switching (reducing input ripple), and automatic transition between 2 MHz PWM and variable-frequency PSM modes.
It integrates P-channel and N-channel MOSFET power switches (RDSON_P = 325 mΩ max, RDSON_N = 275 mΩ max), internal soft-start (270 µs typ), undervoltage lockout (2.28 V rising threshold), thermal shutdown (150°C), and short-circuit protection with frequency foldback. The SYNC pin supports three operating modes: fixed 2 MHz PWM, auto PSM/PWM, or external synchronization from 1.5 MHz to 2.5 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.3 V to 6.5 V - supports single-source multi-cell alkaline/NiMH/Li-ion batteries without external regulation. |
| Output Current (per channel) | 800 mA continuous - guaranteed minimum output capability under worst-case thermal conditions. |
| Quiescent Current | 15 µA (both channels in PSM) - extends battery runtime in standby and light-load states. |
| Switching Frequency | 2 MHz fixed PWM or 1.5–2.5 MHz externally synchronized - enables compact LC filter design and EMI control. |
| Feedback Voltage | 0.8 V (±2.25%) - sets output voltage via external resistor divider; enables adjustable range from 0.8 V to 6 V. |
| Phase Relationship | 180° out-of-phase operation - halves input capacitor RMS current and reduces VIN ripple amplitude. |
| Shutdown Current | 0.1 µA typical - ensures near-zero drain during system sleep or power-off states. |
| Package | 10-lead, 3 mm × 3 mm × 0.75 mm LFCSP - thermally enhanced exposed pad (PGND) for efficient heat dissipation in space-constrained layouts. |
Pinout & Package
ADP2230ACPZ-R7 uses a 10-lead, 3 mm × 3 mm LFCSP package with an exposed thermal pad (EPAD) electrically connected to PGND. The package requires soldering the EPAD to the PCB ground plane for proper thermal performance and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1, SW2 | Power switch node (buck 1 & 2) | Connects internal P/N-MOSFETs to external inductors; high dv/dt node requiring tight layout and local decoupling. |
| VIN1, VIN2 | Input power supply (buck 1 & 2) | Must be tied together; supplies both channels from common 2.3–6.5 V source; not independently controllable. |
| FB1, FB2 | Output voltage feedback (buck 1 & 2) | Sense point for closed-loop regulation; connects to resistor divider for adjustable outputs or internal reference for fixed versions. |
| EN1, EN2 | Precision enable control (buck 1 & 2) | Independent logic-level enables with 1.255 V rising threshold (max); EN2 supports full VIN range (≤6.5 V), EN1 limited to ≤5.5 V. |
| AGND | Analog ground reference | Separate low-noise ground return for feedback and control circuitry; must be routed separately from PGND and joined at single point. |
| SYNC | Frequency control input | Selects operating mode: high = 2 MHz PWM only, low = PSM/PWM auto-transition, 1.5–2.5 MHz clock = external sync with in-phase outputs. |
| PGND (EPAD) | Power ground / thermal pad | Exposed pad on bottom of package; must be soldered to large PCB copper area for thermal conduction and low-impedance PGND connection. |
Key Features
| Feature | Design Value |
|---|---|
| 180° phase-shifted outputs | Reduces input capacitor RMS current by ~30% and minimizes VIN ripple magnitude in dual-buck configurations. |
| Quick Output Discharge (QOD) | Integrated 200 Ω switched resistor discharges VOUT to <100 mV within 1 ms after disable, ensuring safe state transitions. |
| Auto PSM/PWM mode transition | Smoothly shifts between high-efficiency PSM (light load) and stable 2 MHz PWM (medium/heavy load) without output disturbance. |
| Internal soft-start | 270 µs typical ramp time prevents input current overshoot and output voltage undershoot during startup. |
| Thermal & short-circuit protection | 150°C junction shutdown with 15°C hysteresis and frequency foldback during hard short - prevents damage without latch-off. |
| Low dropout 100% duty cycle | Enables regulation down to VOUT ≈ VIN − 0.2 V (at light loads), critical for Li-ion end-of-discharge operation. |
Applications
| Portable Medical Sensors | Mobile Point-of-Sale Terminals |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62400DRVR | Single 2 MHz buck with integrated LDO (not dual buck); lower IQ (19 µA) but no phase shift or SYNC pin. | Limited to single-output + LDO topologies; cannot replace dual independent buck functionality. | Choose only if application requires one main rail + auxiliary low-current LDO, not two fully regulated buck outputs. |
| RT8070ZSP | Dual 1.5 MHz buck with 600 mA per channel, 25 µA IQ, no PSM mode, no external sync, different enable thresholds. | Lower max current and fixed frequency only; lacks light-load efficiency optimization and flexible clock control. | Acceptable where 600 mA/channel suffices and EMI constraints allow 1.5 MHz; avoid when PSM or 2 MHz sync is required. |
Compared with TPS62400DRVR and RT8070ZSP, the ADP2230ACPZ-R7 uniquely delivers dual 800 mA synchronous buck regulation with 180° phase shift, 2 MHz PSM/PWM auto-transition, and external clock synchronization - making it the only option among the three that meets stringent portable instrumentation requirements for efficiency, ripple suppression, and timing flexibility.

FAQ
What is the maximum continuous output current per channel for the ADP2230ACPZ-R7?
The ADP2230ACPZ-R7 guarantees a minimum continuous output current of 800 mA per channel across the full operating temperature range (−40°C to +125°C junction), verified under worst-case thermal conditions with recommended PCB layout and component selection per the datasheet.
Does the ADP2230ACPZ-R7 support adjustable output voltages, and what is the range?
Yes, the ADP2230ACPZ-R7 supports adjustable output voltages from 0.8 V to 6 V using external resistor dividers on FB1/FB2 pins. Its internal feedback reference is 0.8 V (±2.25%), enabling precise regulation across this full range with appropriate compensation.
How does the SYNC pin affect the operation of the ADP2230ACPZ-R7?
The SYNC pin configures three distinct modes: logic-high enables fixed 2 MHz PWM-only operation; logic-low enables automatic PSM/PWM transitioning; and a 1.5–2.5 MHz external clock forces synchronized PWM-only operation with in-phase outputs. The pin has defined thresholds (1.3 V high, 0.4 V low) and leakage <1 µA.
What protection features are integrated into the ADP2230ACPZ-R7?
The ADP2230ACPZ-R7 includes current-limit protection (930–1475 mA P-channel limit), thermal shutdown (150°C with 15°C hysteresis), undervoltage lockout (2.28 V rising threshold), short-circuit protection with frequency foldback, and quick output discharge (200 Ω internal resistor). All operate without external components.
Is the ADP2230ACPZ-R7 pin-compatible with other members of the ADP223x family?
No - the ADP2230ACPZ-R7 is a specific variant with fixed 1.2 V/1.8 V output configuration. Other ADP223x variants (e.g., ADP2231, ADP2232) differ in output voltage pairs or adjustability and share the same pinout but require verification of FB network and enable logic compatibility before substitution.
