Capsuled in the 16-DIP (0.300, 7.62mm) package, the switching controller can be used for a wide range of applications. For outputs of 4, this dc motor controller is suitable. There are PWM dc switching's output (s) that it can handle. Voltages 4V~6V are the dc control's supply voltage and operating voltage, respectively. Worked in an dc switcher with a -40°C~85°C TA rating. With this switching controller, you can switch at 60kHz. A generalization of dc dc regulator can be made using Through Hole. In order to control switching efficiently, the dcdc regulator features Enable, Power Good.
