Flash Blanking (Tx-Mask) for Instantaneous Flash-Current Reduction
The TPS6131x devices offer a dedicated hardware signal input (Tx-Mask) that can be used to reduce the flash
current to the programmed video light level instantaneously.
This feature can be used to reduce the overall current drawn from the battery if other system components require
high energy simultaneously, e.g. during a RF PA transmission pulse.
The Tx-MASK function has no influence on the safety timer duration.

POWER-SAVE MODE OPERATION, EFFICIENCY
The TPS6131x integrates a power-save mode to improve efficiency under light loads. In power-save mode the
converter only operates when the output voltage trips below a set threshold voltage. It ramps up the output
voltage with one-to-several pulses and returns to power-save mode once the output voltage exceeds the set
threshold voltage.
Figure 49. Operation in PFM Mode and Transfer to PWM Mode
The power-save mode can be enabled and disabled via the ENPSM bit. In down conversion mode, power-save
mode is always active and the device cannot be forced into fixed frequency operation at light loads.
The LED sense voltage has a direct effect on converter efficiency. Because the voltage across the low-side
current regulator does not contribute to the output power (LED brightness), the lower the sense voltage the
higher the efficiency will be.
