Product details
Overview
ADP1650ACPZ-R7 from Analog Devices is a 1.5 A I²C-programmable white LED flash driver with integrated 3 MHz synchronous boost converter, designed for high-resolution camera flash in space-constrained mobile devices. It delivers ±7% LED current accuracy at 1500 mA, supports torch mode up to 200 mA, and features thermal protection, LED open/short detection, and 4-bit ADC for VF/temperature monitoring.
For engineers reviewing the ADP1650ACPZ-R7 datasheet, ADP1650ACPZ-R7 pinout, ADP1650ACPZ-R7 application, or ADP1650ACPZ-R7 equivalent, this page provides verified technical context, WLCSP package mapping, I²C register-controlled flash/torch timing, battery current limiting, and real-world safety feature behavior - all confirmed for the ADP1650ACPZ-R7 variant.
Technical Context
The ADP1650ACPZ-R7 integrates a programmable 3 MHz (or 1.5 MHz) synchronous boost converter with integrated PFET/NFET switches (50 mΩ/60 mΩ in WLCSP), enabling operation in both pass-through and boost modes depending on VIN vs. LED VF + headroom. Its 12-ball 0.5 mm pitch WLCSP package supports ultra-compact PCB layouts with minimal inductor height (1 mm, 1 µH).
Control is implemented via I²C-compatible interface (400 kHz max), STROBE input for hardware-synchronized flash, dual TxMASK inputs for dynamic current reduction during PA bursts, and GPIO1/GPIO2 configurable as torch enable, mask inputs, or ADC channels. Safety logic includes timeout fault (up to 1600 ms), overvoltage (5.5 V typ), thermal shutdown (150°C), and LED short/open detection.

Pinout & Package
ADP1650ACPZ-R7 is packaged in a 12-ball Wafer-Level Chip Scale Package (WLCSP) with 0.5 mm ball pitch. The exposed die pad must be connected to PGND for thermal and electrical integrity. Pin functions are defined per JEDEC-standard top-view ball map (ball side down).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Power Input | Connects to 2.7–5.0 V battery rail; requires local 10 µF ceramic bypass capacitor for stable boost operation. |
| SW | Boost Switch Node | Drives external 1 µH inductor; high-frequency switching node requiring tight layout and ground plane coupling. |

| STROBE | Hardware Flash Trigger | Level- or edge-sensitive input synchronizing flash pulse to image sensor capture; supports level-sensitive timeout up to 1600 ms. |
| EN | Enable Control | Active-high logic input; pulls quiescent current to <1 µA when low and resets registers to defaults on rising edge. |
| SCL/SDA | I²C Interface | Standard bidirectional I²C bus pins supporting full register access, status readback, and programmable current/timing configuration. |
| GPIO1 | Configurable I/O | Register-selectable as torch enable, TxMASK1 input, or unused; enables external logic control of assist light without I²C traffic. |
| GPIO2 | Configurable I/O | Register-selectable as red indicator LED driver, TxMASK2 input, or ADC input for VF/die temperature sensing. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED flash driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM3644TME/NOPB | 1.5 A flash driver in 16-pin WQFN; lacks integrated ADC and TxMASK inputs; uses analog torch control instead of I²C. | Better suited for cost-sensitive designs where register-level diagnostics and RF coexistence are not required. | Select LM3644TME/NOPB if I²C register visibility and dual TxMASK are unnecessary and WQFN layout compatibility exists. |
| MAX77693ETO+T | Multi-rail PMIC with integrated 1.5 A flash driver; shares buck/boost regulators and fuel gauge; larger 40-pin TQFN package. | Targeted at full-system PMIC integration rather than dedicated flash-only function; higher pin count and complexity. | Choose MAX77693ETO+T only when consolidating flash, charging, and LDOs into one IC is prioritized over minimal footprint and independent control. |
Compared with LM3644TME/NOPB, ADP1650ACPZ-R7 offers superior diagnostic capability via its 4-bit ADC and tighter current accuracy (±7% vs. ±10%), while MAX77693ETO+T trades flash-specific optimization for broader system integration - making ADP1650ACPZ-R7 optimal for space-constrained, high-reliability flash subsystems.

FAQ
What is the maximum flash duration supported by the ADP1650ACPZ-R7?
The ADP1650ACPZ-R7 supports programmable flash timing up to 1600 ms via the FL_TIM register bits. This maximum duration applies in both hardware strobe (level- or edge-sensitive) and software strobe modes. The actual flash pulse ends earlier if STROBE is deasserted before timeout or if a fault (e.g., thermal, overvoltage) occurs. All timing is internally generated and does not rely on external clocks.
Does the ADP1650ACPZ-R7 require an external Schottky diode?
No, the ADP1650ACPZ-R7 does not require an external Schottky diode. Its synchronous boost converter integrates both high-side PFET and low-side NFET switches (50 mΩ/60 mΩ in WLCSP), eliminating conduction losses and heat generation associated with external diodes. This contributes directly to the 90% peak efficiency and compact solution size cited in the ADP1650ACPZ-R7 datasheet.
How does the ADP1650ACPZ-R7 handle low battery voltage conditions?
The ADP1650ACPZ-R7 implements Low VBAT Mode, which automatically reduces LED current when input voltage drops below a threshold (typically 3.2 V ±3.2%). Hysteresis of 50 mV prevents oscillation near the transition point. This behavior is hardware-based and active in both flash and torch modes, ensuring continued illumination - albeit at reduced intensity - as the battery discharges, without requiring host processor intervention.
Can the ADP1650ACPZ-R7 drive more than one LED?
No, the ADP1650ACPZ-R7 is designed exclusively for driving a single high-brightness white LED. Its current source architecture, feedback loop, and safety protections (e.g., LED open/short detection) are calibrated for one LED anode connected to LED_OUT. Driving multiple LEDs in series would exceed the 5.5 V overvoltage protection threshold; parallel connection would cause unbalanced current sharing and invalidate fault detection - neither configuration is supported by the ADP1650ACPZ-R7 design.
What is the purpose of the TxMASK inputs on the ADP1650ACPZ-R7?
The TxMASK1 and TxMASK2 inputs on the ADP1650ACPZ-R7 provide hardware-level, sub-microsecond response to reduce LED and battery current during cellular/Wi-Fi power amplifier bursts. When asserted, they override I²C-set current values and scale output to preconfigured lower levels, preventing supply rail collapse and image noise. This function is critical for maintaining flash quality during simultaneous RF transmission - a key requirement validated in ADP1650ACPZ-R7 reference designs.
