Product details
Overview
ADP2230ACPZ-1833R7 from Analog Devices is a dual-channel, synchronous step-down DC/DC regulator delivering 800 mA per channel with fixed output voltages of 1.8 V and 3.3 V. It operates from 2.3 V to 6.5 V input, achieves up to 94% efficiency, and features 180° out-of-phase switching to minimize input ripple-ideal for space-constrained portable devices requiring dual-rail power.
For engineers reviewing the ADP2230ACPZ-1833R7 datasheet, ADP2230ACPZ-1833R7 pinout, ADP2230ACPZ-1833R7 application, or ADP2230ACPZ-1833R7 equivalent, key selection criteria include its dual fixed-output configuration (1.8 V/3.3 V), 2 MHz PWM/PSM auto-transitioning mode, low 15 µA quiescent current in PSM, 10-lead 3 mm × 3 mm LFCSP package, and precision enable thresholds for independent channel control.
Technical Context
The ADP2230ACPZ-1833R7 integrates two independent current-mode PWM controllers with proprietary high-speed regulation, enabling stable transient response and seamless PSM/PWM mode transitions based on load. Each channel features internal P- and N-channel MOSFETs with typical RDS(ON) of 325 mΩ (P) and 275 mΩ (N), plus integrated soft-start and quick output discharge (200 Ω switched resistor).
Its SYNC pin supports three operating modes: 2 MHz fixed PWM (SYNC ≥ 1.3 V), automatic PSM/PWM transition (SYNC ≤ 0.4 V), or external clock synchronization (1.5–2.5 MHz). In fixed-output configuration, feedback is internally set-no external resistors required-and both outputs are phase-shifted by 180° to reduce input capacitor RMS current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.3 V to 6.5 V - supports single-source supply from multiple alkaline/NiMH/Li-ion cells without external regulators. |
| Output Voltages | Fixed 1.8 V / 3.3 V pair - eliminates need for external feedback resistors; optimized for core I/O rail separation in portable SoCs. |
| Max Output Current | 800 mA per channel - guaranteed continuous delivery under full thermal limits; enables direct powering of RF transceivers and display drivers. |
| Quiescent Current | 15 µA (both channels in PSM) - extends battery runtime in standby/sleep states of WSN and medical sensors. |
| Switching Frequency | 2 MHz fixed PWM or 1.5–2.5 MHz externally synchronized - allows EMI-sensitive designs to avoid critical frequency bands. |
| Package | 10-lead, 3 mm × 3 mm × 0.75 mm LFCSP - exposes thermal pad (EPAD) tied to PGND; requires PCB ground plane connection for θJA = 44.6°C/W. |
| Protection Features | Current-limit, thermal shutdown (150°C), UVLO (2.28 V rising), and quick output discharge - ensures robust operation during fault conditions without external circuitry. |
Pinout & Package
ADP2230ACPZ-1833R7 uses a 10-lead, 3 mm × 3 mm LFCSP package with exposed thermal pad (EPAD) electrically connected to PGND. The EPAD must be soldered to a solid PCB ground plane for thermal performance and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SW1 | Buck 1 switch node | Connects internal P/N MOSFETs to inductor L1; requires low-inductance layout to minimize switching noise. |
| VIN1 | Buck 1 power input | Must be tied directly to VIN2; supplies both channels from common 2.3–6.5 V source. |
| FB1 | Buck 1 feedback | Internally connected to 1.8 V reference; no external resistor needed for fixed-output operation. |
| EN1 | Buck 1 precision enable | Rising threshold 1.2 V (max); max operating voltage 5.5 V - use resistor divider if VIN > 5.5 V. |
| AGND | Analog ground reference | Separate from PGND; connects to quiet ground plane to maintain feedback accuracy. |
| SYNC | Frequency control input | Selects PWM-only (high), PSM/PWM auto (low), or external sync (1.5–2.5 MHz square wave). |
| EN2 | Buck 2 precision enable | Rising threshold 1.2 V (max); max operating voltage 6.5 V - can connect directly to VIN2. |
| FB2 | Buck 2 feedback | Internally connected to 3.3 V reference; no external components required. |
| VIN2 | Buck 2 power input | Must be tied directly to VIN1; shared input simplifies power routing. |
| SW2 | Buck 2 switch node | Connects internal P/N MOSFETs to inductor L2; 180° phase shift vs. SW1 reduces input ripple. |
| EPAD | Power ground (PGND) | Exposed pad on bottom; must be soldered to large PCB ground plane for thermal and electrical performance. |
Key Features
| Feature | Design Value |
|---|---|
| Dual 180° out-of-phase PWM | Reduces input capacitor RMS current by ~30% versus in-phase operation, allowing smaller CIN (7–10 µF X7R recommended). |
| Auto PSM/PWM transition | Smoothly shifts between 2 MHz PWM (full load) and variable-frequency PSM (light load), maintaining >85% efficiency down to 1 mA. |
| Integrated quick output discharge (QOD) | 200 Ω switched resistor on each SWx pin discharges VOUT to <100 mV within 1 ms after disable - prevents floating rails in sequenced power systems. |
| Independent precision enable inputs | EN1/EN2 each have 200 mV hysteresis and 1.2 V rising threshold, enabling staggered startup/shutdown for power sequencing compliance. |
| Internal compensation & synchronous rectification | Eliminates need for external compensation network and freewheeling diodes - total BOM reduced to five passive components (2×L, 3×C). |

FAQ
What output voltages does the ADP2230ACPZ-1833R7 provide?
The ADP2230ACPZ-1833R7 provides fixed output voltages of 1.8 V on Channel 1 and 3.3 V on Channel 2. These values are factory-trimmed and require no external feedback resistors. The part number suffix "-1833" explicitly denotes this voltage pairing, and internal references ensure ±1.5% accuracy over temperature and line/load conditions as specified in the datasheet.
Does the ADP2230ACPZ-1833R7 support independent enable control for each channel?
Yes, the ADP2230ACPZ-1833R7 features two precision enable inputs: EN1 for Channel 1 (1.8 V) and EN2 for Channel 2 (3.3 V). Each has a 1.2 V rising threshold (max), 200 mV hysteresis, and distinct absolute maximum ratings-EN1 supports up to 5.5 V, EN2 up to 6.5 V-enabling flexible power sequencing without additional level-shifting circuitry.
How does the ADP2230ACPZ-1833R7 minimize input ripple?
The ADP2230ACPZ-1833R7 minimizes input ripple by operating its two buck converters 180° out of phase. This phase shift causes input current harmonics to cancel, reducing RMS input capacitor current by approximately 30% compared to in-phase operation-allowing smaller, lower-ESR input capacitors (7–10 µF X7R) while maintaining stability.
What protection features are integrated into the ADP2230ACPZ-1833R7?
The ADP2230ACPZ-1833R7 integrates current-limit protection (930–1475 mA P-channel, 300–625 mA N-channel), thermal shutdown at 150°C with 15°C hysteresis, undervoltage lockout (2.28 V rising), soft-start (270 µs typical), and quick output discharge (200 Ω internal resistor). These functions operate autonomously without external components, ensuring robustness in portable and medical applications.
Can the ADP2230ACPZ-1833R7 be synchronized to an external clock?
Yes, the ADP2230ACPZ-1833R7 supports external clock synchronization via the SYNC pin. When a 1.5 MHz to 2.5 MHz square wave is applied, the device locks to the external frequency, disables PSM mode, and forces both channels into fixed-frequency PWM operation-in phase with the applied clock. This capability enables precise EMI management in noise-sensitive systems like medical imaging or audio interfaces.
