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. With the above
functions, this part provides customers a compact, high
efficiency, well-protected and cost-effective solution. This
part comes to VQFN-16L 4x4, SOP14 and SSOP-16
packages.
