TPS54900

illustrate

The TPS54900 quad buck converter uses voltage-mode PWM control and provides four independently programmable output voltages. Each channel includes a specification and a typical one_targetR ON SWITCH FOR HIGH-END PMOSFET_{0.8 Deputy Director General (} This makes it high efficiency, low current applications. The command sent to the TPS54900 in a four-wire serial port scenario yields an independent or global supply voltage from 0.4 to V increments of 7.5 V to 13.1 five. When the input voltage is required for the output, the bypass mode can be activated, maximizing the switching circuit of the PMOSFET and closing the selected channel.

The TPS54900 is an ideal companion device as part of the AC5 central office ADSL chip to power the THS7102 ADSL line driver.
