BD9540EFV-E2 Product Details

BD9540EFV-E2 Overview


It comes in the 28-VSSOP (0.173, 4.40mm Width) package, which makes switching controller suitable for most applications. 2 outputs can be generated with the dc motor controller. An enclosure of Tape & Reel (TR) is used to package the PMIC. A total of Transistor Driver dc switching's outputs can be handled by it. dc controls with 7.5V~20V voltage are supplied and operated. Suitable for a -20°C~100°C TA dc switcher. A generalization of dc dc regulator can be made using Surface Mount. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . 28 terminations with various dc switching's functions. DC switcher's voltage input is 12V. You can find other relevant dc to dc converter ics by searching "BD9540". There is a particular type of Switching Regulator or Controllers in switching converter. According to the test statistics, DC regulator outputs 5.5V voltage. DC switcher's Surface Mount qualifies it for most applications and prototypes. Because the dc switcher's maximum input voltage is 20V users must limit the voltage accordingly. The supply voltage must be 7.5V. Datasheets state the switching converter can output up to 5.5V volts.
