1.5A/4.1A Multiple LED Camera Flash Driver With I²C^TMCompatible Interface

FEATURES

DESCRIPTION

•

Four Operational Modes

The TPS6132x device is based on a high-frequency

synchronous boost topology with constant current

sinks to drive up to three white LEDs in parallel

(445mA/890mA/445mA maximum flash current). The

extended high-current mode (HC_SEL) allows up

to 1025mA/2050mA/1025mA flash current out of

the storage capacitor.

–

DC Light and Flashlight

Voltage Regulated Converter: 3.8V...5.7V

Standby: 2mA (typ.)

•

Storage Capacitor Friendly Solution

Automatic V_Fand ESR Calibration

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.

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 3.4Mbits/s

Dual Wire Camera Module Interface

Zero Latency Tx-Masking Input

LED Temperature Monitoring

Privacy Indicator LED Output

Integrated LED Safety Timer

The 2-MHz switching frequency allows the use of

small and low profile 2.2mH inductors. To optimize

overall efficiency, the device operates with a 400mV

LED feedback voltage.

•

The TPS6132x 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.

GPIO/Flash Ready Output

Total Solution Size of Less Than 25 mm²

(<1mm height)

•

Available in a 20-Pin NanoFree™ (CSP)

To simplify DC light and flashlight synchronization

APPLICATIONS

with the camera module, the device offers

dedicated control interface (STRB0, STRB1) for zero

latency LED turn-on time.
