Additional Details:

The RT8284N utilizes a constant-on-time (COT) control architecture to achieve fast transient response and stable operation. The device also features an internal soft-start circuit to limit inrush current during startup, preventing voltage overshoot. Over-current protection (OCP), short-circuit protection (SCP), and over-temperature protection (OTP) are integrated to ensure robust operation and protect the device and the load from damage. The RT8284N is available in a space-saving WQFN-16 (3x3) package.
