LTC3890MPGN-1#TRPBF Overview
With its 28-SSOP (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. The dc motor controller is adquate to generate for 2 outputs. There is a Tape & Reel (TR) solid enclosure around the pmic. Transistor Driver dc switching's outputs (s) are supported. dc control's supply and operating voltages are 4V~60V. Worked in an dc switcher with a -55°C~150°C TJ rating. Switching can be done at 105kHz~835kHz 350kHz~535kHz with this switching controller. dc dc regulator can be generalized using Surface Mount. The dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking 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 . An array of 28 terminations of dc switching. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. You can find other relevant dc to dc converter ics by searching "LTC3890". 28 pins are on switching converter. This dc dc voltage regulator should be powered by a voltage of 4V. Voltages 60V are the maximum that the dc to dc regulator will accept. DC regulator850kHz has the maximum frequency. Channels 1 are required for high-quality communication.
