This new series of drivers, designated the TPS281x family, is used in switching power supplies to achieve a small, light weight, and efficient power supply system. The family also incorporates a wide range of logic functions in the drive logic to give engineers more flexibility when designing systems.
The TPS281x devices provide up to 2 Amps of peak current while driving high capacitive loads. They are designed to minimize shoot-through currents and to consume very low supply currents while providing optimum rise and fall times. The drivers operate over a 4 to 14 Volt range. The TPS2811, TPS2812 and TPS2813 also incorporate an internal voltage regulator which extends the operating range up to 40 volts. This minimizes the number of external components required in higher voltage systems.
20 ns maximum rise/fall time Provides maximum efficiency for high with 30 ns maximum prop. delay frequency operation. 2A peak output current Devices can drive FETs up to approximately 60W and still maintain good efficiency. 5 uA supply current Allows for better system efficiency/ performance. Low cost Devices can replace existing discrete designs and at a lower cost than current competitive products. On-board linear regulator Allows extended supply voltage operation to 40 Volts for higher voltage systems.
