BD9845FV-E2 Overview
It comes in the 14-LSSOP (0.173, 4.40mm Width) package, which makes switching controller suitable for most applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. Tape & Reel (TR) solid enclosure protects the pmic. There are Transistor Driver dc switching's output (s) that it can handle. DC control operates at 3.6V~35V volts and has 3.6V~35V supply voltage. Suitable for work in a -40°C~85°C TA dc switcher. There is a switch at 100kHz~1.5MHz that can be used with this controller. It is suitable for general dc dc regulator when it is set to Surface Mount. Featured in the dcdc regulator is Dead Time Control, Enable, Frequency Control, Soft Start which allows efficient switching control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. There are a terminal (s) on the switching converters that are designed at DUAL. 14 terminations with a variety of function. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. 6V nominal DC switcher's voltage input. A search for "BD9845" will reveal other relevant dc to dc converter ics. There are a total of 14 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. 3.6V should be the minimum input voltage for the dc dc voltage regulator. A 35V voltage of DC regulator was detected in the test statistics. You should note down the dc dc regulator's usual output current of 1A when you start a project. This Surface Mount makes DC switcher suitable for most prototypes and applications. DC regulators have a maximum frequency of 1.5MHz. For safe and reliable operation in a circuit, voltage regulator dc to dc is suggested that users apply 35V. There will be 13mA output current greater than 13mA from the dc switcher.
