RT9259 12V Synchronous Buck PWM DC-DC and Linear Power Controller General Description The RT9259 is a dual-channel DC/DC controller specifically designed to deliver high quality power where 12V power source is available. This part consists of a synchronous buck controller and an LDO controller. The synchronous buck controller integrates MOSFET drivers that support 12V+12V bootstrapped voltage for high efficiency power conversion. The bootstrap diode is built-in to simplify the circuit design and minimize external part count. The LDO controller drives an external N-MOSFET for lower power requirement. Other features include adjustable operation frequency, internal soft start, under voltage protection, over current protection and shut down function.
