9 Power Supply Recommendations

The TPS65090A device integrates a power path management system that automatically switches power to the load from either an AC adapter or from battery power. The voltage range for the AC adapter should fall within the 6 V to 17 V range. Battery power can be provided by either a dual or triple Li-Ion or Li-Polymer cell battery pack. On power up, the battery pack is connected to the load by default. However, if a valid voltage is detected on the VACS pin and the voltage on the VAC pin is higher than the battery voltage, the battery is disconnected and the AC adapter is connected to the load through the external power path switches.
