SLVS751E November 2007 – January 2024 TPS5430-Q1
PRODUCTION DATA
TI recommends the TPS5430-Q1 to operate with input voltages above 5.5 V. The typical VIN UVLO threshold is 5.3 V and the device can operate at input voltages down to the UVLO voltage. At input voltages below the actual UVLO voltage the device does not switch. If ENA is floating or externally pulled up to greater up than 1.3 V, when V(VIN) passes the UVLO threshold the device becomes active. Switching is enabled and the slow-start sequence is initiated. The TPS5430-Q1 starts linearly ramping up the internal reference voltage from 0 V to its final value over the internal slow-start time period.
