SLVSCQ8A December 2015 – April 2016 TPS54A20
PRODUCTION DATA.
Refer to the PDF data sheet for device specific package drawings
The TPS54A20 is designed to operate from an input voltage supply range between 8V and 14V. This supply voltage must be well regulated. Power supplies must be well bypassed for proper electrical performance. This includes a minimum of one 4.7μF (after de-rating) ceramic capacitor, type X5R or better, from VIN to PGND. Additional local ceramic bypass capacitance may be required in systems with small input ripple specifications, in addition to bulk capacitance, if the TPS54A20 device is located more than a few inches away from its input power supply. In systems with an auxiliary power rail available, the power stage input, VIN, and the gate driver power input, VG+, may operate from separate input supplies. See the recommendations in the Layout section for further explanation.
