5 / 57 page  TPS61310, TPS61311 www.ti.com SLVS978C – MARCH 2010 – REVISED NOVEMBER 2012 ELECTRICAL CHARACTERISTICS (Continued) Unless otherwise noted the specification applies for VIN = 3.6V over an operating junction temp. –40°C ≤ TJ ≤ 125°C; Circuit of Parameter Measurement Information section (unless otherwise noted). Typical values are for TJ = 25°C. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT TIMING tNRESET Reset pulse width 10 μs From shutdown into video light mode Start-up time 1.2 ms ILED = 150mA LED current settling time(1) triggered MODE_CTRL[1:0] = 10 500 μs by a rising edge on STRB0 ILED2 = from 0mA to 950mA LED current settling time(1) triggered MODE_CTRL[1:0] = 10 20 μs by Tx-MASK ILED2 = from 950mA to 150mA (1) Settling time to ±15% of the target value.
