General Description
The RT8259A is a monolithic step-down switch mode converter with a built-in power MOSFET. It achieves 1.5A output current over a wide input supply range with excellent load and line regulation. Current Mode operation provides fast transient response and eases loop stabilization. The chip also provides protection functions such as cycle-by-cycle current limiting and thermal shutdown protection.
