Working Principle

TPS75003MRHLREP is based on a low quiescent current synchronous buck switching regulator with a synchronous rectifier. It is designed to be voltage-lock compatible, the output voltage is set via a resistor divider.The TPS75003MRHLREP works in four stages: The start-up, the cycle period, the transition, and the stop.When the device is first turned on, a startup circuit provides a bias voltage to enable the IC, and the IC begins to pull out from the low quiescent current standby mode. In the “regular” cycle period, the TPS75003MRHLREP transforms the input voltage to the designated output voltage. The synchronous rectifier in the converter improves the conversion efficiency by using a low resistance current path to minimize energy losses in the device. After the transition period, which is a period of transition between cycling modes, the cycle is completed and the device is returned to the low quiescent current standby mode.

Conclusion

In conclusion, the TPS75003MRHLREP is a specialized DC-DC converter that uses a low quiescent current, easy-touse enable and synchronous rectifier configuration and a wide input/output voltage range to provide high power densities in small-size applications.
