CS51221EDR16 Overview
With a 16-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. 1 outputs can be generated with the dc motor controller. A solid enclosure of Tape & Reel (TR) surrounds pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). 3.8V~15V is the operating voltage and supply voltage of the dc control. A -40°C~85°C TA dc switcher is not a problem. As it has a Surface Mount value, it can be used for general dc dc regulator. DCDC regulator is controlled efficiently by Current Limit, Frequency Control, Ramp, Soft Start. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . A variety of dc switching's functions can be performed on 16 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. You can find other relevant dc to dc converter ics by searching "CS51221". Total pins of switching converter are 16. The type is a particular Switching Regulator or Controllers of switching converter. Input voltage of dc dc voltage regulator should be 4.7V. DC regulator outputs 15V voltage based on test statistics. You should note that the dc dc regulator's usual output current is 1A. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 90 %. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. There is 1MHz frequency setting on the switching controller.
