CS51221EDTB16G Overview


This switching controller fits most application requirements since it is packaged in a 16-TSSOP (0.173, 4.40mm Width) package. 1 outputs are supported by the dc motor controller. An enclosure of Tube is used to package the PMIC. A total of Transistor Driver dc switching's outputs can be handled by it. 3.8V~15V is the operating voltage and supply voltage of the dc control. Worked in an dc switcher with a -40°C~85°C TA rating. dc dc regulator is made easier with Surface Mount. Switching control is made easier with the dcdc regulator's Current Limit, Frequency Control, Ramp, Soft Start. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a DUAL terminal on the switching converters. 16 terminations with various dc switching's functions. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. Other relevant dc to dc converter ics will be returned if you search "CS51221". Total pins of switching converter are 16. In particular, switching converter belongs to the Switching Regulator or Controllers family. Input voltage of dc dc voltage regulator should be 4.7V. DC regulator outputs 15V voltage according to the test statistics. If you are starting a new project, you should note the dc dc regulator's typical output current is 1A. Voltage regulator dc to dc is designed to operate at 90 % duty cycle during power-ups and power-downs to ensure reliability. 1MHz is the maximum frequency of this dc regulators.
