CS51221EDTB16R2G Product Details
CS51221EDTB16R2G Overview
With a 16-TSSOP (0.173, 4.40mm Width) package, the switching controller is suitable for a wide range of applications. It is sufficient to generate 1 outputs with this dc motor controller. The pmic is packaged in Tape & Reel (TR) solid enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sA 3.8V~15V voltage is supplied to the dc control and used for operating it. Worked in an dc switcher with a -40°C~85°C TA rating. The Surface Mount allows it to be used for dc dc regulator in general. Featured in the dcdc regulator is Current Limit, Frequency Control, Ramp, Soft Start which allows efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. A variety of 16 terminations are available in dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. In addition to "CS51221", there are other relevant dc to dc converter ics you can find. 16 pins are on switching converter. Switching converter is a special type of Switching Regulator or Controllers. It is recommended that the input voltage of the dc dc voltage regulator be 4.7V. Test statistics indicate DC regulator outputs 15V voltage. If you are starting a new project, you should note the dc dc regulator's typical output current is 1A. The duty cycle of the voltage regulator dc to dc can be set to 90 % on power-up or power-down to ensure reliability. This dc regulatorhas a max frequency of 1MHz.
