Product details
Overview
ADP2230ACPZ-1233R7 from Analog Devices is a dual-channel, synchronous step-down DC/DC regulator delivering fixed 1.2 V and 3.3 V outputs with 800 mA per channel, operating from 2.3 V to 6.5 V input, achieving up to 94% efficiency and 15 µA quiescent current in power-saving mode - deployed in portable medical instruments and battery-powered point-of-sale terminals.
For engineers reviewing the ADP2230ACPZ-1233R7 datasheet, ADP2230ACPZ-1233R7 pinout, ADP2230ACPZ-1233R7 application, or ADP2230ACPZ-1233R7 equivalent, key selection criteria include dual fixed-output pairing, 180° phase-shifted switching for reduced input ripple, 2 MHz PWM/PSM auto-transitioning operation, and LFCSP-10 package thermal performance in space-constrained portable designs.
Technical Context
The ADP2230ACPZ-1233R7 integrates two independent current-mode PWM controllers with proprietary high-speed control architecture, enabling stable regulation and fast transient response across load steps from 10 mA to 800 mA. Each channel features internal P/N-channel MOSFETs (RDSON_P = 325 mΩ max, RDSON_N = 275 mΩ max) and precision enable logic with 1.255 V rising threshold and 1.1 V falling threshold.
It supports three frequency control modes via the SYNC pin: 2 MHz fixed PWM (SYNC ≥ 1.3 V), automatic PSM/PWM transition (SYNC ≤ 0.4 V), or external synchronization from 1.5 MHz to 2.5 MHz. Outputs operate 180° out of phase in PWM/PSM modes but in-phase when externally synchronized - directly impacting input capacitor sizing and EMI behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.3 V to 6.5 V - supports single-cell Li-ion, dual alkaline/NiMH, and USB-powered systems without pre-regulation. |
| Output Voltage Pair | Fixed 1.2 V / 3.3 V - eliminates external feedback resistors; enables direct powering of core logic and I/O rails in SoC/FPGA applications. |
| Max Output Current | 800 mA per channel - sufficient for powering ARM Cortex-M microcontrollers, sensors, and display interfaces simultaneously. |
| Quiescent Current | 15 µA (both channels in PSM) - extends battery runtime in always-on WSN nodes and metering devices. |
| Switching Frequency | 2 MHz fixed PWM or auto-transitioning PSM/PWM - allows use of compact 2.2 µH inductors and 10 µF ceramic capacitors for <48 mm² total solution size. |
| Phase Relationship | 180° out-of-phase PWM - reduces peak input current by ~30% and cuts required input capacitance versus in-phase operation. |
| Protection Features | Thermal shutdown (150°C), current limit (1.475 A P-ch), UVLO (2.28 V rise), and quick output discharge (200 Ω internal switch) - ensures robustness in unattended portable equipment. |
Pinout & Package
ADP2230ACPZ-1233R7 is housed in a 10-lead, 3 mm × 3 mm × 0.75 mm LFCSP package with exposed PGND pad (EPAD) for enhanced thermal dissipation. The package requires soldering the EPAD to a PCB ground plane per JEDEC J-STD-020 guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1, SW2 | Power switch node for Buck 1 and Buck 2 | Connects to respective inductor; carries high di/dt switching current - requires short, low-inductance routing and local ceramic decoupling. |
| VIN1, VIN2 | Input power supply for each buck channel | Must be tied together externally; shared 2.3–6.5 V rail powers both regulators - simplifies board layout but mandates common input source. |
| FB1, FB2 | Feedback input for regulated output voltage | Internally connected to 0.8 V reference; unused for fixed-output variant ADP2230ACPZ-1233R7 - leave floating or omit external resistor divider. |
| EN1, EN2 | Independent precision enable inputs | Enable each buck with 1.255 V rising threshold; EN2 supports full VIN range (≤6.5 V), EN1 limited to ≤5.5 V - critical for sequenced power-up in multi-rail systems. |
| SYNC | Frequency control and synchronization input | Selects 2 MHz PWM (high), auto PSM/PWM (low), or external clock sync (1.5–2.5 MHz) - determines noise-efficiency trade-off and input ripple profile. |
| AGND | Analog ground reference | Separate from PGND in layout; connects to quiet ground plane to minimize noise coupling into feedback and oscillator circuits. |
| PGND / EPAD | Power ground and thermal pad | Electrically tied to internal PGND; must be soldered to large PCB copper area for θJA = 44.6°C/W and reliable 800 mA operation at +85°C ambient. |
Key Features
| Feature | Design Value |
|---|---|
| Dual fixed 1.2 V / 3.3 V outputs | Eliminates four external feedback resistors and associated layout area - reduces BOM count and improves production yield in high-volume portable designs. |
| 180° phase-shifted PWM operation | Cuts peak input current ripple by half versus in-phase switching - permits smaller input capacitors (7 µF min) and lowers EMI filter requirements. |
| 2 MHz PSM/PWM auto-transitioning | Maintains >85% efficiency down to 100 µA load while limiting light-load output ripple to <20 mVpp - ideal for intermittent-sensing IoT endpoints. |
| Integrated quick output discharge (QOD) | 200 Ω internal switch discharges VOUT to <100 mV within 1 ms of disable - prevents back-powering, meets IEC 61000-4-2 system-level ESD recovery requirements. |
| Internal compensation and synchronous rectification | Removes need for external compensation network and Schottky diodes - achieves full 800 mA capability with only five external components (2×L, 3×C). |

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 |
|---|---|---|---|
| TPS62403DRVR | Fixed 1.2 V / 3.3 V pair; 2.25–6.5 V input; 600 mA per channel; 2.25 MHz fixed PWM only; no PSM mode. | Lacks light-load efficiency optimization - unsuitable for multi-year battery applications with long idle periods. | Choose when strict 2.25 MHz EMI profile is required and load never drops below 10 mA. |
| RT8070ZSP | Adjustable dual buck; 2.5–5.5 V input; 800 mA per channel; 1.5 MHz fixed PWM; no phase shift or QOD. | Requires external feedback resistors; no built-in output discharge - adds BOM cost and fails fast-turnoff safety checks. | Choose only if adjustable outputs are mandatory and board space allows larger passive components. |
Compared with TPS62403DRVR and RT8070ZSP, ADP2230ACPZ-1233R7 uniquely combines fixed dual outputs, 180° phase shift, PSM/PWM auto-transitioning, and integrated QOD in a 3 mm × 3 mm LFCSP - making it the only option meeting simultaneous requirements for ultra-low quiescent current, minimal solution size, and safe power sequencing in portable medical and metering designs.

FAQ
What input voltage range does the ADP2230ACPZ-1233R7 support?
The ADP2230ACPZ-1233R7 operates from 2.3 V to 6.5 V on VIN1 and VIN2, which must be connected together. This range accommodates single-cell Li-ion (2.7–4.2 V), dual alkaline/NiMH (2.4–3.2 V), and USB-powered (4.75–5.25 V) systems without external pre-regulation. Operation below 2.3 V triggers undervoltage lockout at 2.28 V (rising), preventing unstable regulation.
Does the ADP2230ACPZ-1233R7 require external feedback resistors for its 1.2 V and 3.3 V outputs?
No, the ADP2230ACPZ-1233R7 is the fixed-output variant with internally trimmed 1.2 V and 3.3 V references - FB1 and FB2 pins are not used and may be left unconnected. Its output accuracy is guaranteed at ±2% (1.168–1.220 V for 1.2 V; 3.202–3.363 V for 3.3 V) over temperature and line/load conditions, eliminating resistor tolerance and drift concerns.
How does the SYNC pin affect operation of the ADP2230ACPZ-1233R7?
The SYNC pin configures three modes: tie high (≥1.3 V) for 2 MHz fixed PWM; tie low (≤0.4 V) for automatic PSM/PWM transition; or apply 1.5–2.5 MHz external clock for synchronization. In PWM/PSM modes, outputs are 180° out-of-phase; with external sync, they operate in-phase and PSM is disabled - directly influencing input ripple, EMI, and light-load efficiency.
What thermal considerations apply to the ADP2230ACPZ-1233R7 in continuous 800 mA operation?
At 800 mA per channel and 5 V input, ADP2230ACPZ-1233R7 dissipates ~0.5 W. With θJA = 44.6°C/W on a 4-layer board, junction temperature rises ~22°C above ambient. To maintain TJ ≤ 125°C, keep ambient ≤ 103°C - achieved by soldering the EPAD to ≥200 mm² copper area and avoiding component crowding above the package.
Is quick output discharge (QOD) active on both channels of the ADP2230ACPZ-1233R7?
Yes, ADP2230ACPZ-1233R7 integrates independent 200 Ω switched discharge resistors on both SW1 and SW2 pins. When either EN1 or EN2 is pulled low, the corresponding output discharges to <100 mV within 1 ms - ensuring safe state transitions, preventing back-powering of upstream circuitry, and supporting IEC 61000-4-2 compliant system-level ESD recovery sequences.
