The RT8159 is a dual-channel DC/DC regulator controller specifically designed for dual outputs application in which 12V power source is available. This part consists of a synchronous rectified buck PWM controller and a low-dropout linear regulator (LDO) controller. The buck PWM controller utilizes voltage-mode control with external compensation. The MOSFET gate drivers and bootstrap diode are all integrated in the controller to minimize external component count. The MOSFET gate drivers provide 12V driving voltage for high-side and low-side MOSFETs to achieve high efficiency power conversion. The LDO controller drives an external N-MOSFET for low power application. Other features include adjustable oscillator frequency, internal soft start, fast transient response, under voltage protection, enable/disable control, and over current protection for PWM output. With the above functions, RT8159 provides customers a compact, high efficiency, and cost-effective solution.
