TPS55340RTER Description
The TPS55340RTER is an integrated 5A wide input range
boost/SEPIC/flyback DC/DC regulator in 16 pin WQFN package. This is
a monolithic, non-synchronous, switching regulator with integrated
5A, 40V power switch. The device can be configured in several
standard switching-regulator topologies, including boost, SEPIC and
isolated flyback. The device has a wide input voltage range to
support applications with input voltage from multicell batteries or
regulated 3.3V, 5V, 12Vand 24V power rails. It regulates output
voltage with current mode PWM (pulse width modulation) control and
has an internal oscillator. The switching frequency of PWM is set
by either an external resistor or by synchronizing to an external
clock signal. It features a programmable soft-start function to
limit inrush current during start-up and has other built-in
protection features including cycle-by-cycle overcurrent limit and
thermal shutdown. It is used in thunderbolt port, USB Type-C power
delivery & power docking.
