The TPS55065 is a switched-mode regulator with integrated switches for voltage-mode control. With the aid of external components (LC combination), the device regulates the output to 5 V ±3% for a wide input-voltage range.

The TPS55065 device offers a reset function to detect and indicate when the 5-V output rail is outside of the specified tolerance. This reset delay is programmable using an external timing capacitor on the REST terminal. Additionally, an alarm (A_OUT) feature is activated when the input supply rail V_driver is below a prescaled specified value (set by the A_IN terminal).

The TPS55065 device has a frequency-modulation scheme to minimize EMI. The clock modulator permits a modulation of the switching frequency to reduce interference energy in the frequency band.

The 5-Vg output is a switched 5-V regulated output with internal current limiting to prevent assertion of RESET when powering a capacitive load on the supply line. This function is controlled by the 5Vg_ENABLE terminal. If there is a short to ground on this output (5Vg output), the output self-protects by operating in a chopping mode. This does, however, increase the output ripple voltage on V_OUT during this fault condition.
