Overview
RT9259C
12V Synchronous Buck PWM DC-DC and Linear Power Controller
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.
Other features include adjustable operation frequency, internal soft start, under voltage pr...
