As a result of SOIC compact design, the switching controller is compatible with most applications. The dc motor controller is adquate to generate for 1 outputs. A switching controller such as this can switch at a value of 2MHz . Switch converters are connected to ICs with SWITCHING REGULATOR analog outputs. DUAL  are the position of the terminal of the switching converters. An array of 8 terminations of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. There are 8 pins on switching converter. Switching converter is a special type of Switching Regulator or Controllers. Voltage regulator dc to dc is designed to operate at 96 % duty cycle during power-ups and power-downs to ensure reliability. DC switcher's Surface Mount qualifies it for most applications and prototypes. Switching controllers work at 2MHz Hz. At -40°C and above, dc regulator should be kept. DC regulator should run at a temperature 105°C higher than 105°C. 1 functions are available in total for the switch converters. Voltage regulators switching is designed with 8 pins. The controller can set a maximum frequency of 2MHz. A 1A input switching controller would benefit from it. As far as maximum supply voltage is concerned, switching voltage regulators is rated as 30V.
