UCC39421N Overview
This switching controller fits most application requirements since it is packaged in a 16-DIP (0.300, 7.62mm) package. This dc motor controller can be used to generate outputs with 1 numbers. Packaged in solid enclosures, this pmic has a Tube rating. It is capable of handling Transistor Driver dc switching's outputs (s). 1.8V~8V is the operating voltage and supply voltage of the dc control. Worked in an dc switcher with a 0°C~70°C TA rating. This switching controller can switch at 150kHz~1.2MHz. The Through Hole makes it ideal for general dc dc regulator. Enable, Frequency Control, Low Battery, Reset 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 DUAL . A variety of 16 terminations are available in dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. 3V nominal DC switcher's voltage input. The dc to dc regulator can only accept 8V input voltage. This value is CONFIGURABLE VOLTAGE MODE; PROGRAMMABLE PFM TECHNIQUE so that DC to DC voltage regulator better serves the purpose.
