RT8292BHZSP

The RT8292BHZSP is a DC-DC switching regulator designed for high-efficiency synchronous rectification of small to medium power sources. This high-performance regulator features high current capability, high efficient operation over a wide range of input and output voltages, and provides superior power supply rejection (PSR). It is also capable of providing adjustable and fixed output voltages.

The main applications for the RT8292BHZSP include high-current point-of-load voltage regulators that are used for industrial, communications, and consumer electronic applications, such as power rails in CPUs and FPGAs, intermediate bus converter (IBC), smart phones, tablets, networking switches, and power adapters.

The RT8292BHZSP operates in a synchronous rectification operation mode, in which both an upper switch MOSFET and a lower switch MOSFET connected in push-pull configuration are turned on and off by the switch control logic. When the upper switch is turned off, the current flows through the lower switch and is stored in the inductor, and then the energy is transferred to the output capacitor during the upper switch on state. To reduce voltage ripple, a compensation network is used to adjust the rise and fall time of the current to match the on/off switching status of the upper/lower switches.

The RT8292BHZSP also includes many protection features, such as thermal protection circuit and input UVLO, which ensure safe and reliable operation. The thermal protection circuit will shut down the device when the die temperature exceeds the maximum junction temperature, while the input UVLO protects the device from over-voltage or under-voltage conditions. Furthermore, the device also features a power OK output, which is used to indicate the presence of an output voltage.

Overall, the RT8292BHZSP is an ideal DC-DC switching regulator for high-current point-of-load applications, offering high efficiency, high power supply rejection and a range of protection features. It is easy to configure and install, and provides reliable output voltage for a wide range of input and output voltages, making it an excellent choice for any power conversion application.
