We are trying to use the TPS65130 to provide +/- supply to two Op-Amps which are being used to drive two transducers which operate at 2MHz. Our current issue is that when running these amplifiers with a bench top DC supply we operate with around 300mA (~150mA per Amplifier), but when we try supplying from the TPS65130 the current climbs to 1.5 A (Current seen by bench top supply).
The signal going into the TPS65130 and the Op-Amps is a 3.3V 2MHz signal from an MSP430 EVM board, which will be using a battery supply.
