ZHCSCK0C June 2014 – September 2021 TPS55340-Q1
PRODUCTION DATA
The enable rising-edge threshold voltage is 1.08 V (typical) with 0.16-V hysteresis (typical). With the EN pin held below the turn-off voltage, the device is disabled and switching is inhibited. The IC quiescent current is reduced in this state. When the input voltage is above the UVLO threshold and the EN pin voltage increases above the rising edge threshold, the device becomes active. Switching enables and the soft-start sequence initiates. The TPS55340-Q1 device starts at the soft-start time determined by the external soft-start capacitor.
