TPS9103 Datasheet (Texas Instruments)

TPS9103, POWER SUPPLY

The TPS9103 is a highly integrated power supply for depletion-mode GaAs power amplifiers (PA) in cellular handsets and other wireless communications equipment.

Functional integration and low-profile packaging combine to minimize circuit-board area and component height requirements.

The device includ
