9 Power Supply Recommendations

The DLPA1000 is designed to operate from a 2.3-V to 6-V input voltage supply or battery. To avoid insufficient supply current due to line drop, ringing due to trace inductance at the VIN terminal, or supply peak current limitations, additional bulk capacitance may be required. Electrolytic or tantalum type capacitors can dampen ringing often caused by ceramic input capacitors. The amount of bulk capacitance required should be evaluated such that the input voltage can remain in specification long enough for a proper fast shutdown to occur for the VOFS, VRST, and VBIAS supplies. The shutdown begins when the input voltage drops below the programmable UVLO threshold such as when the external power supply or battery supply is suddenly removed from the system.
