BD9845FV is a DC-DC buck controller designed for step-down voltage regulation applications. It operates with an input voltage range of 3.6V to 35V and features a built-in FET driver circuit for efficient power management. The device includes an adjustable soft start function, over-current protection, and supports three operational modes: standby, master, and slave, with a typical standby current of 0 ¬µA. The oscillation frequency can be set between 100 kHz and 1.5 MHz, making it suitable for various applications including LCDs, printers, and projectors. The product is housed in a compact 14-pin SSOP package, measuring 5.00 mm x 6.40 mm x 1.35 mm, and operates within a temperature range of -40¬8C to +85¬8C.
