ZHCSF14D March 2010 – October 2018 TPS54260
PRODUCTION DATA.
The TPS54260 is recommended to operate with input voltages above 3.5 V. The typical VIN UVLO threshold is 2.5 V and the device may operate at input voltages down to the UVLO voltage. At input voltages below the actual UVLO voltage, the device will not switch. If EN is floating or externally pulled up to greater than the typical 1.25-V threshold, when V(VIN) passes the UVLO threshold the TPS54260 will become active. Switching is enabled and the slow-start sequence is initiated. The TPS54260 ramps up the output voltage at the slow-start time determined by the capacitance on the SS/TR pin.
