UCC39421PWTR Overview


Capsuled in the 16-TSSOP (0.173, 4.40mm Width) package, the switching controller suits most application needs. 1 outputs are supported by the dc motor controller. PMIC packaging is solid with a Tape & Reel (TR) enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sdc control's supply and operating voltages are 1.8V~8V. Suitable for work in a 0°C~70°C TA dc switcher. In this switching controller, the switch can be set to 150kHz~1.2MHz. The Surface Mount makes it ideal for general dc dc regulator. The dcdc regulator features Enable, Frequency Control, Low Battery, Reset for efficient switching control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. Thare switching converters has a terminal (s) at DUAL . 16 terminations with a variety of function. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis 3V volts. Search for "UCC39421" to find other relevant dc to dc converter ics. In total, switching converter has 16 pins. DC regulator outputs 8V voltage based on test statistics. At most, the dc to dc regulator accepts 8V input voltage. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. DC regulators have a maximum frequency of 2MHz. Hence, CONFIGURABLE PEAK CURRENT MODE; PROGRAMMABLE PFM TECHNIQUE is used to better suit the DC to DC voltage regulator's situation. For safe and reliable operation in a circuit, voltage regulator dc to dc is suggested that users apply 8V.
