TPS55340RTER

The TPS55340 is a monolithic, nonsynchronous,
switching regulator with integrated 5-A, 40-V 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
3.3-V, 5-V, 12-V, and 24-V power rails.
The TPS55340 regulates the 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. The user
can program the switching frequency from
100 kHz to 1.2 MHz.
The device features a programmable soft-start
function to limit inrush current during start-up and
has other built-in protection features including cycleby-cycle overcurrent limit and thermal shutdown.
The TPS55340 is available in a small 3-mm × 3-mm
16-pin QFN as well as 14-pin HTSSOP packages with
PowerPAD for enhanced thermal performance.
The 5-A, 40-V TPS55340 boost converter in the
HTSSOP-14 package is pin-to-pin compatible with the
3-A, 40-V TPS61175, and it extends the maximum
input voltage from 18 V to 32 V
