Working principle

TPS51461RGER synchronous buck DC-DC converter converts an input voltage of 4.5V to 14V to an adjustable output voltage of 0.8V to 12V. It operates in either a continuous or discontinuous conduction mode, which is determined by the output load.

It operates at a fixed switching frequency of up to 1MHz to reduce the size and cost of the external components. An internal high side and low side MOSFETs allow for maximum efficiency and higher output currents. Output voltage regulation is achieved by using a fixed frequency, voltage-mode control loop.

The integrated MOSFETs are controlled by a bipolar pulse width modulation (PWM) controller. It uses an internal current sense module to provide voltage regulation feedback and is supported by an adjustable soft-start, an adjustable frequency foldback, and an adjustable current limit.

In addition, the integrated soft-start prevents inrush current during start-up and the adjustable frequency foldback reduces the switching frequency when the current limit is reached to ensure stable operation. Furthermore, an integrated Schottky diode eliminates the need for an external diode.
