Texas Instruments TPS61300YFFR

Overview

TPS61300YFFR from Texas Instruments is a 1.5-A multiple LED camera flash driver IC with synchronous boost topology, I²C interface (up to 3.4 Mbps), and hardware DC light control (ENDCL). It delivers up to 400 mA/800 mA/400 mA per LED channel in standard mode or 925 mA/1850 mA/925 mA in extended high-current mode (HC_SEL), operating from 2.5 V–5.5 V input for smartphone flashlight and privacy indicator applications.

For engineers reviewing the TPS61300YFFR datasheet, TPS61300YFFR pinout, TPS61300YFFR application, or TPS61300YFFR equivalent, key selection criteria include its 20-pin DSBGA package (1.90 mm × 2.20 mm), 400-mV LED sense voltage, integrated storage capacitor balancing (BAL), zero-latency FLASH_SYNC trigger, and dual-mode operation (constant-current LED drive + regulated voltage boost).

Technical Context

The TPS61300YFFR implements a 2-MHz synchronous boost converter with three independent constant-current sinks for parallel white LED driving. Its architecture supports both regulated current output (for flash/DC light) and regulated voltage output (VOUT preset to 4.95 V in ENVM mode), maintaining regulation even when input exceeds nominal output voltage.

It integrates automatic VF and ESR calibration, power-save mode for >95% efficiency at light loads, and hardware-triggered operational mode switching via ENDCL, Tx-MASK, and FLASH_SYNC inputs - enabling precise synchronization with camera modules and RF PA events without I²C latency.

FAQ

What is the primary function of the TPS61300YFFR in a mobile camera system?

The TPS61300YFFR serves as a highly integrated LED flash driver IC that delivers precise constant-current control to up to three white LEDs. It operates in both DC light mode (for video recording) and high-current flashlight mode (for still capture), using a synchronous boost converter and hardware-triggered inputs like FLASH_SYNC and ENDCL. Its 400-mV LED sense voltage, 2-MHz switching frequency, and DSBGA package make it ideal for thin smartphone camera modules where efficiency, size, and timing precision are critical. The TPS61300YFFR also supports voltage regulation mode for auxiliary rails.

How does the HC_SEL pin affect LED current capability in the TPS61300YFFR?

The HC_SEL pin configures the TPS61300YFFR between two distinct operational modes: when pulled LOW, it enables direct-drive LED current (400 mA/800 mA/400 mA for LED1/LED2/LED3); when pulled HIGH, it activates extended high-current mode using a storage capacitor, raising maximum currents to 925 mA/1850 mA/925 mA. This mode shift changes internal power stage behavior and current-limit thresholds - confirmed in the Electrical Characteristics table for both HC_SEL states. The TPS61300YFFR requires explicit external termination of HC_SEL; floating is prohibited.

Can the TPS61300YFFR drive a privacy indicator LED independently of the main flash channels?

Yes, the TPS61300YFFR includes a dedicated INDLED pin that provides a constant-current source (2.6–7.9 mA, ±20% accuracy) for driving low-forward-voltage indicator LEDs. This output is electrically isolated from the LED1–LED3 current sinks and can be enabled or disabled independently via I²C registers. Its 0.04%/°C temperature coefficient ensures stable brightness across operating temperatures. Unlike the main flash channels, INDLED does not support hardware triggers like FLASH_SYNC - making it ideal for always-on or software-controlled privacy status indicators in laptops or tablets using the TPS61300YFFR.

What is the role of the BAL pin on the TPS61300YFFR, and which applications require it?

The BAL pin on the TPS61300YFFR provides active cell balancing for dual-cell supercapacitors used in flash energy storage. It sinks or sources up to ±15 mA to compensate for leakage current mismatches between series-connected cells, extending usable hold time and preventing overvoltage on individual cells. This function is essential in high-reliability flashlight designs where supercapacitors replace electrolytics - particularly in premium smartphones and ruggedized devices. The TPS61300YFFR's BAL circuit draws only 1.7–6 μA quiescent current into VOUT when balanced, minimizing standby loss. Applications without supercapacitors or using single-cell storage do not utilize the BAL pin.

Does the TPS61300YFFR support I²C communication at speeds above standard mode, and what are the timing constraints?

Yes, the TPS61300YFFR supports I²C high-speed mode up to 3.4 Mbps for both read and write operations, provided bus capacitance stays ≤100 pF. Its timing specifications define strict limits: tLOW and tHIGH must each be ≥160 ns, rise/fall times ≤40 ns, and data setup/hold times ≥10 ns/≥70 ns respectively. These constraints ensure robust register access during rapid flash parameter updates (e.g., intensity, duration, safety timer). The TPS61300YFFR also supports standard (100 kHz) and fast (400 kHz) modes for backward compatibility. All I²C pins (SCL, SDA) include internal pull-down resistors (~350 kΩ), but external pull-ups remain mandatory per I²C specification.
