PMIC - Voltage Regulators - DC DC Switching Regulators

The RT8295BHZSP is a mono-channel, high performance synchronous rectifying step-down (buck) switching regulator with a typical dropout voltage of 0.2V/V. It provides maximum 18V of input voltage and up to 5A of output current, thus it is suitable for powering diverse kinds of low-voltage and medium-to-high current applications, such as computers, motherboards and telecoms.

Application Field

Applications for the RT8295BHZSP include portable devices, digital media players and cellular phones, where minimizing power consumption is essential. This converter also features overcurrent and short circuit protection, allowing it to be used as a direct connection to a CPU core or memory power supply. It also provides excellent dv/dt filtering performance on light load, thus helping reduce EMI noises.

The RT8295BHZSP can be used in applications such as LCD display backlighting, home appliances and other power related applications where the output voltage has to be well regulated and easily adjusted.

Working Principle

The RT8295BHZSP is a monolithic integrated synchronous rectifying dc-dc switching regulator. It employs an over-current protection block that provides protection against output current overloads as well as over-voltage conditions. The RT8295BHZSP uses a voltage-mode control method and an internal undershoot protection circuit to limit the output voltage from dropping below the regulation voltage. The device utilizes a synchronous rectifier in the monitor voltage feedback divider circuit for improved efficiency and a single-loop control for fast voltage loop response.

The RT8295BHZSP also has power saving features, where the quiescent current is reduced as the output load current approaches zero. Moreover, this app is capable of supporting dynamic voltage scaling and soft start. Furthermore, the RT8295BHZSP also features skip mode, whereby the conversion frequency switches to 500 kHz, allowing higher efficiency with zero load.

Conclusion

The RT8295BHZSP is a versatile and reliable DC-DC switching regulator, ideal for a range of applications where minimal power consumption is desirable. It can provide up to 5A of output current and an input voltage range of 0.6V to 18V. Additionally, it employs overcurrent and under-voltage protection and dynamic voltage scaling, making it a perfect choice for power related tasks.
