PRODUCTION DATA. TPS61300, TPS61301 TPS61305, TPS61305A, TPS61306 SLVS957E – JUNE 2009 – REVISED APRIL 2016 TPS6130xx 1.5-A and 4.1-A Multiple LED Camera Flash Driver With I2C Compatible Interface 1 1 Features 1 • Four Operational Modes – DC Light and Flashlight – Voltage Regulated Converter: 3.8 V to 5.7 V – Standby: 2 μA (Typical) • Storage Capacitor Friendly Solution • Automatic VF and ESR Calibration • Power-Save Mode for Improved Efficiency at Low Output Power, Up to 95% Efficiency • Output Voltage Remains Regulated When Input Voltage Exceeds Nominal Output Voltage • I2C Compatible Interface up to 3.4 Mbits/s • Zero Latency Tx-Masking Input • Hardware Voltage Mode Selection Input (TPS61300, TPS61301) • DC Light Mode Selection Input (TPS61300, TPS61306) • Hardware Reset Input (TPS61301, TPS61305) • LED Temperature Monitoring (TPS61305) • Privacy Indicator LED Output • Integrated LED Safety Timer • Total Solution Size of Less Than 25 mm2 (< 1 mm height) • Available in a 20-Pin NanoFree™ (DSBGA) 2 Applications • Single, Dual, or Triple White LED Flashlight Supply for Cell Phones and Smart-Phones • LED Based Xenon Killer Flashlight • Audio Amplifier Power Supply 3 Description The TPS6130xx device is based on a high-frequency synchronous boost topology with constant current sinks to drive up to three white LEDs in parallel (400 ‑mA, 800-mA, and 400-mA maximum flash current). The extended high-current mode (HC_SEL) allows up to 1025-mA, 2050-mA, and 1025-mA flash current out of the storage capacitor. The high-capacity storage capacitor on the output of the boost regulator provides the high-peak flash LED current, thereby reducing the peak current demand from the battery to a minimum. The 2-MHz switching frequency allows the use of small and low profile 2.2- μH inductors. To optimize overall efficiency, the device operates with a 400-mV LED feedback voltage. The TPS6130xx device not only operates as a regulated current source, but also as a standard voltage boost regulator. The device keeps the output voltage regulated even when the input voltage exceeds the nominal output voltage. The device enters power-save mode operation at light load currents to maintain high efficiency over the entire load current range. To simplify flashlight synchronization with the camera module, the device offers a trigger pin (FLASH_SYNC) for zero latency LED turnon time. Table 1.
