UCC38C42DG4 Overview
As a result of 8-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. There is sufficient capacity to generate switching controller for outputs 1. PMIC is packaged in a solid enclosure of Tube. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching's9V~18V is the supply voltage and the operating voltage of the dc control. Suitable for working in an dc switcher that has a 0°C~70°C TJ. With this switching controller, you can switch at Up to 1MHz. The Surface Mount makes it ideal for general dc dc regulator. DCDC regulator is controlled efficiently by Frequency Control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. A variety of terminations with 8 of dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's voltage input is 15V. A search for "UCC38C42" will reveal other relevant dc to dc converter ics. In total, switching converter has 8 pins. There is a particular type of Switching Regulator or Controllers in switching converter. A 18V voltage of DC regulator was detected in the test statistics. You should note down the dc dc regulator's usual output current of 200mA when you start a project. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 100 %. This Surface Mount makes DC switcher suitable for most prototypes and applications. The switching controller works at a frequency of 1MHz. DC to DC voltage regulator has a value of ALSO OPERATES IN CURRENT MODE to better satisfy the need. 18V is the nominal working voltage.
