RT9259CPA規(guī)格書詳情
General Description
The RT9259C 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 builtin to simplify the circuit design and minimize external part count. The LDO controller drives an external N-MOSFET for lower power requirement.
