RT9266GE

The RT9266GE is a DC-DC switching regulator designed for use in embedded applications, specifically those that require high output current. This regulator is capable of handling currents of up to 12A, making it well suited for use in battery powered or high current applications. Additionally, the built-in features reduce the size of the external components needed, making it well suited for space-constrained applications.

In terms of external components, the RT9266GE requires only an input voltage capacitor, output voltage capacitor, resonator, and an inductor. The voltage requirement for the input capacitor is generally between 4.5V to 18V, and for the output capacitor, it should generally be between 2.5V to 6.5V. The required resonator is chosen based on the desired frequency, and the inductor value is selected based on the desired inductor current.

In terms of features, the RT9266GE has a wide range of features that provide flexibility to the given application. One of the features is the adjustable switching frequency, which can be adjusted from 0.5MHz to 2.5MHz. In addition, the RT9266GE includes built-in protection features such as short-circuit protection, over-voltage protection, over-current protection, and thermal shut-down protection. Finally, the regulator is available in both DIP and SOP packages, making it compatible with a variety of applications.

In terms of operation, the RT9266GE is based on a pulse width modulation (PWM) architecture, with a fixed frequency of 500kHz. Once the enable pin is activated, the regulator begins to convert the input voltage to the desired output voltage, using PWM. By changing the duty cycle, the regulator is able to maintain a stable output voltage even if the input voltage fluctuates. To put this into practice, the RT9266GE uses a pulse width modulator (PWM) to modulate the input voltage. The general rule of thumb is that the bigger the input voltage difference, the greater the duty cycle is needed to maintain a stable output voltage.

In conclusion, the RT9266GE is an ideal DC-DC switching regulator for embedded applications due to its high power handling capabilities and range of features. From adjustable switching frequency, to built-in protection features, the RT9266GE makes it easy to design reliable and efficient power solutions. And with both DIP and SOP packages available, the RT9266GE allows for maximum flexibility when designing power systems.
