LTC3890HGN-3#TRPBF Product Details
LTC3890HGN-3#TRPBF Overview
Capsuled in the 28-SSOP (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. For 2 outputs, the dc motor controller is appropriate. The pmic is packaged in Tape & Reel (TR) solid enclosure. Transistor Driver dc switching's outputs (s) are supported. 4V~60V is the operating voltage and supply voltage of the dc control. Suitable for working in an dc switcher that has a -40°C~150°C TJ. A switching controller such as this can switch at a value of 105kHz~835kHz 350kHz~535kHz . dc dc regulators can be carried out with Surface Mount. Enable, Frequency Control, Power Good, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. Switching converters are designed with the terminal (s) at position DUAL . An array of 28 terminations of dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. A search for "LTC3890" will reveal other relevant dc to dc converter ics. Switching converter is a type of Switching Regulator or Controllers in particular. It is recommended to use 4V as the minimum input voltage of dc dc voltage regulator. The dc to dc regulator is limited to 60V input voltage.
