Switching Regulator
A switching regulator is a voltage regulator that uses a switching element to transform the incoming power supply into a pulsed voltage, which is then smoothed using capacitors, inductors, and other elements.
Power is supplied from the input to the output by turning ON a switch (MOSFET) until the desired voltage is reached.
Once the output voltage reaches the predetermined value the switch element is turned OFF and no input power is consumed.
Repeating this operation at high speeds makes it possible to supply voltage efficiently and with less heat generation.

Description for the TPS54360B
The TPS54360B is a 60-V, 3.5-A, step-down regulator with an integrated high side MOSFET. Current mode control provides simple external compensation and flexible component selection. A low ripple pulse skip mode reduces the no-load supply current to 146 µA. Shutdown supply current is reduced to 2 µA when the enable pin is pulled low.
Undervoltage lockout is internally set at 4.3 V but can be increased using the enable pin. The output voltage start-up ramp is internally controlled to provide a controlled start-up and eliminate overshoot.
A wide switching-frequency range allows either efficiency or external component size to be optimized. Frequency foldback and thermal shutdown protect internal and external components during an overload condition.
The TPS54360B is available in an 8-pin thermally enhanced HSOIC PowerPAD™ package.
