Product details
Overview
TPS61310YFFT from Texas Instruments is a 1.5-A synchronous boost LED flash and video light driver with I²C interface, supporting up to three white LEDs in parallel. It operates from 2.5 V to 5.5 V input, delivers regulated LED current up to 950 mA on LED2 (typical), and integrates temperature monitoring, open/short LED protection, and automatic battery droop compensation for smartphone camera modules.
For engineers reviewing the TPS61310YFFT datasheet, TPS61310YFFT pinout, TPS61310YFFT application, or TPS61310YFFT equivalent, key selection criteria include its 20-pin DSBGA package, 2-MHz switching frequency enabling 2.2-µH inductors, I²C-compatible interface up to 3.4 Mbps, zero-latency strobe control via STRB0/STRB1, and integrated privacy indicator (INDLED) output.
Technical Context
The TPS61310YFFT implements a synchronous boost converter topology with combinable current sinks per LED channel (LED1–LED3), operating in flash strobe, video light, or voltage-regulated converter modes. Its adaptive output-voltage regulation (3.825 V to 5.7 V) and low 400-mV LED sense voltage minimize power loss across current-sense resistors.
Control logic includes hardware reset (NRESET), RF PA synchronization (Tx-MASK), thermal shutdown (140°C), and LED safety timer. The device enters power-save mode at light loads to maintain up to 95% efficiency and supports dual-wire camera module interface timing with sub-20 µs current settling on Tx-MASK transitions.
Key Specifications

Pinout & Package
TPS61310YFFT is housed in a 20-pin NanoFree™ DSBGA package (2.20 mm × 1.90 mm), optimized for ultra-thin mobile camera modules. The package uses chip-scale ball grid array construction with no wire bonds, minimizing parasitic inductance and thermal resistance (RθJA = 71 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AVIN | Power Input | Main supply input (2.5–5.5 V); connects directly to input bypass capacitor for stable boost operation. |
| VOUT | Boost Output | Regulated output node feeding LED anodes; supports voltage regulation mode (3.825–5.7 V) or current sink operation. |
| SW | Switch Node | Drain of internal high-side MOSFET; connects to inductor switch node; requires low-ESR ceramic output capacitor. |
| LED1, LED2, LED3 | Current Sink Inputs | LED cathode return paths; each regulates current via internal 400-mV sense reference; independent digital control via I²C. |
| PGND / AGND | Ground Returns | Separate power (PGND) and analog (AGND) grounds reduce noise coupling into sensitive current-sense circuitry. |
| SDA / SCL | I²C Interface | Open-drain bidirectional data and clock lines; support standard/fast/high-speed modes up to 3.4 Mbps. |
| STRB0 / STRB1 | Strobe Control | Dedicated hardware inputs for zero-latency flash enable (STRB0) and mode selection (video vs. flash, STRB1). |
| NRESET | Hardware Reset | Active-low master reset; forces shutdown and clears I²C registers; internal 400-kΩ pulldown ensures defined state. |
| TS | Temperature Sense | Analog input for NTC thermistor (220 kΩ) to monitor LED temperature and trigger thermal derating or shutdown. |
| INDLED | Privacy Indicator | Constant-current source (2.6–15.8 mA) for driving low-VF privacy LED; independent of main flash channels. |
| GPIO/PG | Configurable I/O | Default open-drain Power Good output signaling VOUT regulation status; reconfigurable as general-purpose I/O. |
| Tx-MASK | RF Sync Input | Hardware input to instantly reduce LED current from flash to video level, minimizing battery peak load during RF transmission. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED flash driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61311YFFT | Higher input valley current limit (2480 mA vs. 1750 mA); identical pinout, package, and feature set. | Supports higher total LED current (e.g., triple 500-mA LEDs) where TPS61310YFFT reaches current limit. | Select TPS61311YFFT when system requires >1.5-A aggregate LED drive capability under same thermal constraints. |
| LM3644TME/NOPB | 2.5-A max LED current, 1.5-MHz switching, integrated I²C, but lacks Tx-MASK input and INDLED output. | No RF sync capability or dedicated privacy LED driver; requires external circuitry for those functions. | Choose LM3644TME/NOPB only if Tx-MASK and INDLED features are not required and higher peak current is prioritized. |
Compared with TPS61310YFFT, TPS61311YFFT offers higher current headroom with identical layout and firmware compatibility, while LM3644TME/NOPB trades away critical smartphone-specific features (Tx-MASK, INDLED) for raw current capability-making TPS61310YFFT optimal for integrated privacy-aware camera systems.

FAQ
What is the maximum continuous LED current supported by the TPS61310YFFT on the LED2 channel?
The TPS61310YFFT supports up to 950 mA continuous LED current on the LED2 channel under typical operating conditions (TJ ≤ 85°C). This value is confirmed in the Electrical Characteristics table for LED2 current accuracy testing at full-scale current, and aligns with the device's 1.5-A input valley current limit and thermal design envelope in the 20-pin DSBGA package.
Does the TPS61310YFFT require external components for basic flash operation?
Yes, the TPS61310YFFT requires external components including a 2.2-µH power inductor, input/output ceramic capacitors (10 µF and 4.7 µF minimum), current-sense resistors for LED feedback (not integrated), and an NTC thermistor for TS input if temperature monitoring is used. The datasheet Figure 2 shows the complete minimal application circuit with these elements.
How does the Tx-MASK function improve RF coexistence in smartphone designs using the TPS61310YFFT?
The Tx-MASK input on the TPS61310YFFT enables instantaneous reduction of LED current from flash level (e.g., 950 mA) to video level (e.g., 150 mA) within 20 µs, preventing battery voltage droop during RF power amplifier transmission. This avoids interference with cellular/Wi-Fi signal integrity and eliminates the need for additional battery decoupling capacitance in tight-layout mobile designs.
Can the TPS61310YFFT operate as a general-purpose boost converter, not just an LED driver?
Yes, the TPS61310YFFT can operate in voltage-regulated converter mode with output range 3.825 V to 5.7 V, functioning as a standard boost regulator. This mode is explicitly documented in the Features and Description sections and is useful for powering auxiliary circuits like audio amplifiers, where the device's power-save mode maintains >90% efficiency at light loads.
What is the purpose of the INDLED pin on the TPS61310YFFT, and what current range does it support?
The INDLED pin on the TPS61310YFFT provides a dedicated constant-current source for driving a privacy indicator LED, supporting 2.6 mA to 15.8 mA with ±20% accuracy. It operates independently of the main LED channels and is intended for user-facing visual feedback indicating active camera/microphone use, satisfying regulatory privacy requirements without consuming flash power resources.
