MAX1993ETG+ Overview
This switching controller fits most application requirements since it is packaged in a 24-WFQFN Exposed Pad package. The dc motor controller is adquate to generate for 1 outputs. The pmic is packaged in Tube solid enclosure. Transistor Driver dc switching's outputs (s) can be handled by it. The supply and operating voltage of the dc control are 4.5V~5.5V. A -40°C~85°C TA dc switcher is not a problem. The switching controller can be switched at 200kHz 300kHz 450kHz 600kHz. Surface Mount makes it suitable for general dc dc regulator. Current Limit, Enable, On Time Control, Power Good, Pulse Skipping, Saturation provides dcdc regulator efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Switching converters are designed with the terminal (s) at position QUAD . A variety of terminations with 24 of dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The DC switcher's nominal voltage is 5V. MAX1993 can be used to locate other relevant dc to dc converter ics. 24 pins are present on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. It is recommended that the input voltage of the dc dc voltage regulator be 4.5V. As determined by the test statistics, the output voltage of DC regulator is 5.5V. You should note that the dc dc regulator's usual output current is 3A. The maximum duty cycle of this voltage regulator dc to dc is set to 100 % to ensure reliability during power-up and power-down. The Surface Mount makes DC switcher suitable for most applications and prototypes. DC regulator600kHz has the maximum frequency. In order to satisfy the need, DC to DC voltage regulator has a value of CAN ALSO OPERATE IN PFM MODE. In order to run the voltage regulator dc to dc safely and reliably, users are advised to apply 28V. There are several dc to dc voltage regulator in the Quick-PWM? series. The supply current is 1mA.
