TPS54678 data sheet, product information and support

hiccup overcurrent protection and thermal shutdown protectthe device during an overcurrent condition. ，。

and minimizing the IC footprint with a small 3-mm 3-mm thermally enhancedWQFN package. TPS54678 provides accurate regulation for a variety of loads with an accurate 1% voltagereference (VREF) over temperature. Efficiency is maximized through the integrated 12-m MOSFETs. Using the enable (EN) pin， reducing inductor size by enabling up to 2-MHzswitching frequency， synchronous step-down current mode converterwith two integrated MOSFETs. TPS54678 enables small designs by integrating the MOSFETs， 6-A， implementing current modecontrol to reduce external component count，shutdown supply current is reduced by disabling the device. The output voltage start-up ramp is controlled by the soft-start (SS) pin that can alsobe configured for sequencing or tracking. Monotonic start-up is achieved with prebiased voltage.Undervoltage lockout can be increased by programming the threshold with a resistor divider on theenable pin. An open-drain power good signal indicates the output is within 93% to 105% of itsnominal voltage. Cycle-by-cycle current limit， TPS54678 device is a full-featured 6-V。
