4.5V to 28V Input Single Synchronous Buck DC/DC Controller - BD9FZ00F (New)

BD9FZ00F is single synchronous buck DC/DC controller with built-in driver circuit for external two N-ch MOSFETs. With its original constant on-time control method which operates low consumption at light load, this product is ideal for equipment and devices that demand minimal shutdown power consumption. Input voltage is 4.5V to 28V wide range. This device operates on the power supply system of 24V/12V/5V type. It is a constant on-time control system to provide high speed load response.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
