TPS75003MRHLREP is a step-down DC-DC converter specialized for power system integrations. It\'s an ultra-low quiescent current DC-DC converter that utilizes easy-to-used enable and synchronous rectifier configuration. It has an input voltage range of 4.5V to 20V, and output voltage range of 0.6V to 15V, with a maximum output current of 1.2A. With a compact footprint and wide input/output voltage range, TPS75003MRHLREP is the ideal choice for applications with small size, long battery life, and high power density.
Application Field
TPS75003MRHLREP has a wide range of applications, such as power system design and power source design. It can be used in automotive, personal electronics, industrial, embedded systems, instrumentation systems, etc.Furthermore, TPS75003MRHLREP can also be used as a voltage regulator for digital and analog signals, or for more sensitive devices like motion sensors and temperature sensors. For example, in digital devices, its application includes DSPs, ASICs, digital media players, etc., while in analog circuits its application includes power supplies, active power monitors, etc.
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. It has a wide range of applications in automotive, personal electronics, industrial, embedded systems, and instrumentation systems, as well as providing voltage regulation for both digital and analog circuits.
