If an output capacitor is selected with an ESR value ≤ 120 mΩ, its RMS ripple current rating always meets the application requirements. Just for completeness, the RMS ripple current is calculated as: V 1 - O VI 1 IRMS(CO ) = VO ´ ´ L ´ f 2´ 3 (5) The overall output ripple voltage is the sum of the voltage spike caused by the output capacitor ESR plus the voltage ripple caused by charging and discharging the output capacitor: VO VI L ´ f 1 DVO = VO ´ æ ö 1 ´ ç + ESR ÷ è 8 ´ CO ´ f ø (6) Where the highest output voltage ripple occurs at the highest input voltage VI.

The input capacitor should have a minimum value of 10 μF and can be increased without any limit for better input voltage filtering. The input capacitor should be rated for the maximum input ripple current calculated as: IRMS = IO(max) ´ VO VI æ V ö ´ ç 1- O ÷ VI ø è (7) The worst case RMS ripple current occurs at D = 0.5 and is calculated as: IRMS I = O 2 Ceramic capacitor show a good performance because of their low ESR value, and they are less sensitive against voltage transients compared to tantalum capacitors. Place the input capacitor as close as possible to the input pin of the IC for best performance. 14 Submit Documentation Feedback Copyright © 2000–2015, Texas Instruments Incorporated Product Folder Links: TPS62000 TPS62001 TPS62002 TPS62003 TPS62004 TPS62005 TPS62006 TPS62007 TPS62008 TPS62000, TPS62001, TPS62002, TPS62003 TPS62004, TPS62005, TPS62006, TPS62007, TPS62008 www.ti.com SLVS294F – SEPTEMBER 2000 – REVISED AUGUST 2015 9.2.3 Application Curves 100 VO = 2.5 V Efficiency − % 90 VI = 3.6 V 80 70 VI = 5 V 60 50 40 0.1 1 10 100 IO − Load Current − mA 1000 Figure 6.

The input power supply's output current needs to be rated according to the supply voltage, output voltage and output current of the TPS6200x. 11 Layout 11.1 Layout Guidelines As for all switching power supplies, the layout is an important step in the design especially at high peak currents and switching frequencies. If the layout is not carefully done, the regulator might show stability problems as well as EMI problems. Therefore, use wide and short traces for the main current paths as indicted in bold in Figure 19. The input capacitor should be placed as close as possible to the IC pins as well as the inductor and output capacitor. Place the bypass capacitor, C3, as close as possible to the FC pin. The analog ground, GND, and the power ground, PGND, need to be separated. Use a common ground node as shown in Figure 19 to minimize the effects of ground noise. 11.2 Layout Example 1 VI VIN L EN FB L1 9 VO + 8 Ci R3 5 R1 TPS62000 6 C(ff) 4 ILIM PG + PG Co 7 SYNC GND 3 10 PGND FC R2 C3 2 Figure 19.
