Working Principle

The TPS626751YFDR works on the principle of buck-boost switching regulator, with a wide range of output voltage from 0.8V to 5.5V. It is based on an integrated circuit with discretes and features a low quiescent current of ≤3 μA. The component uses an internal high-side switch, low-side switch and two external resistors to determine the output voltage, as illustrated in the figure below. Any capacitor type can be used and the capacitor size affects the output regulation and total solution cost.

The component includes an input voltage range from 3.7V to 18V, as well as an output voltage range from 0.8V to 5.5V. The component also has internal protection capabilities, such as under-voltage lockout (UVLO) and over-voltage protection (OVP).

The switching frequency of the regulator is set to 500kHz, offering high switching efficiency and performance. Its under-voltage lockout prevents it from supplying the load when the input voltage falls below the nominal operating voltage.

Finally, the component features an advanced current-mode control, with a fast response to dynamic loads, such as high-current transients.
