Application Circuit, 2.5 V to 1.5 V Figure 12 shows the schematic for a typical TPS54010 application. The TPS54010 can provide up to 14-A output current at a nominal output voltage To begin the design process, a few parameters must of 1.5 V. Nominal input voltages are 2.5 V for PVIN be decided. The designer needs to know: and 3.3 V for VIN. For proper thermal performance, • Input voltage range the exposed PowerPAD underneath the device must be soldered down to the printed-circuit board. • Output voltage • Input ripple voltage • Output ripple voltage The following design procedure can be used to select • Output current rating component values for the TPS54010. Alternately, the • Operating frequency SWIFT Designer Software may be used to generate a complete design. The SWIFT Designer Software uses For this design example, use the following as the an iterative design procedure and accesses a com- input parameters: prehensive database of components when generating a design. This section presents a simplified dis- cussion of the design process. DESIGN PARAMETER EXAMPLE VALUE Input voltage (VIN) 3.3 V Input voltage range (PVIN) 2.2 to 3.5 V Output voltage 1.5 V Input ripple voltage 300 mV Output ripple voltage 50 mV Output current rating 14 A 10 |
