Description : 12V Synchronous Buck PWM DC-DC and Linear Power Controller
The RT9259A 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.
Description : Advanced PWM and Dual Linear Power Controller
The RT9228 is a 3-in-one power controller optimized for high-performance microprocessor and computer applications. The IC integrates a synchronous buck PWM controller, a linear regulator, and a linear controller as well as monitoring and protection functions into a 24-pin SOP package. The PWM controller regulates the microprocessor core voltage. The linear regulator provides power for the clock driver circuit and the linear controller regulates power for the GTL bus.
