The TPS54617 (U1) can provide up to 6A of output current at a nominal output voltage of 1.8 V. For proper thermal performance, the exposed thermal PowerPAD underneath the integrated circuit, TPS54617, package must be soldered to the printed-circuit board. Analog and power grounds are ties at the pad under the package of the IC Figure 10. Application Circuit The values for the components used in this design The input voltage is a nominal 3.3 or 5 VDC. The example were selected for best load transient input filter capacitors (C1 and C2) are 10-µF ceramic response and small PCB area. Additional design capacitors (MuRata). C12 is a 0.01-µF ceramic information is available at www.ti.com. capacitor that provides high-frequency decoupling of the TPS54617 from the input supply. C1, C2 and C12 must be located as close as possible to the device. Input ripple current is shared among C1, C2 and C12. 8 Submit Documentation Feedback Copyright © 2008, Texas Instruments Incorporated Product Folder Link(s) :TPS54617 |
