The TPS55340RTER is a nonsynchronous monolithic switching regulator with an inbuilt 5-A, 40-V power switch. Boost, SEPIC, and isolated flyback are among the standard switching-regulator topologies that the device can be configured in. The device accepts a wide range of input voltages, allowing it to work with multi-cell batteries or regulated 3.3-V, 5-V, 12-V, and 24-V power rails.
The TPS55340RTER features an inbuilt oscillator and controls the output voltage using current mode PWM (pulse width modulation). An external resistor or synchronization to an external clock signal can be used to set the switching frequency of PWM. The switching frequency can be set anywhere between 100 kHz and 1.2 MHz by the user.

TPS55340RTER Functional Block Diagram
TPS55340RTER Application Circuit
DC-DC converters are high-frequency power conversion circuits that smooth out switching noise into regulated DC voltages using high-frequency switching and inductors, transformers, and capacitors.
DC-DC converters come in non-isolated and isolated varieties. Isolation is determined by whether or not the input ground is connected to the output ground.
The buck, boost, buck-boost, and SEPIC converters are four popular topologies that designers may find useful.
1 Buck Converter
A buck converter reduces the voltage, resulting in a voltage that is lower than the input voltage. From a 5 V USB supply, a buck converter might be used to charge a lithium-ion battery to 4.2 V.
2 Boost Converters
A boost converter increases the voltage by a factor of two, resulting in a voltage that is higher than the input voltage. A boost converter could be used to power a string of LED s or generate a 5 V USB output from a lithium battery.
3 Buck-Boost Converters
A buck-boost converter steps a voltage up or down, resulting in a voltage that is equal to, higher than, or lower than the input voltage. To get a 12 V output from a 12 V battery, a buck-boost could be employed. The voltage of a 12V battery can range from 10 to 14.7 volts. A single cell might also be used to power an LED with a buck-boost, The forward voltage loss of an LED can be as high as 3 volts. The voltage of a lithium battery cell can range from 2.5 to 4.2 volts. Positive and negative voltages are produced by buck-boosts.
4 SEPIC Converters
A SEPIC converter can also step a voltage up or down, resulting in a voltage that is equal to, higher than, or lower than the input voltage. A SEPIC is similar to a buck-boost in that it is used for similar applications, but it has some advantages in particular cases.
