UC3846QTR Overview
Capsuled in the 20-LCC (J-Lead) package, the switching controller suits most application needs. The dc motor controller is adquate to generate for 2 outputs. PMIC packaging is solid with a Tape & Reel (TR) enclosure. The program can handle Transistor Driver dc switching's outputs (s). dc controls with 6.95V~40V voltage are supplied and operated. A 0°C~70°C TA dc switcher is not a problem. The switching controller is capable of switching at the 500kHz position. dc dc regulator can be generalized using Surface Mount. For efficient switching control, the dcdc regulator features Current Limit, Enable, Frequency Control, Soft Start. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. switching converters terminal (s) are designed to be at QUAD. Various 20 terminations. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. Other relevant dc to dc converter ics can be found by searching "UC3846". 20 pins are on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. DC regulator outputs 13.5V voltage according to the test statistics. If you start a project, note down the dc dc regulator's usual output current of 500mA. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. The switching controller works at a frequency of 450kHz. It is possible to set the input voltage as 15V for nominal working statuses.
