LTC3857IGN-1#TRPBF Product Details

LTC3857IGN-1#TRPBF Overview


This switching controller fits most application requirements since it is packaged in a 28-SSOP (0.154, 3.90mm Width) package. For 2 outputs, the dc motor controller is appropriate. PMIC is packaged in a solid enclosure of Tape & Reel (TR). There are Transistor Driver dc switching's output (s) that it can handle. A 4V~38V voltage is supplied to the dc control and used for operating it. Suitable for work in a -40°C~125°C TJ dc switcher. With this switching controller, you can switch at 105kHz~835kHz 350kHz~535kHz. dc dc regulators can be carried out with Surface Mount. To ensure efficient switching, this dcdc regulator features a Enable, Frequency Control, Power Good, Soft Start, Tracking. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. A switching converters's terminal (s) sits at the DUAL position. 28 terminations with a variety of function. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input of 12V. Other relevant dc to dc converter ics will be returned if you search "LTC3857". 28 pins are present on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. Input voltage of dc dc voltage regulator should be 4V. Test statistics indicate DC regulator outputs 24V voltage. The dc to dc regulator can only accept a maximum input voltage of 38V. DC regulator850kHz has the maximum frequency. There are several dc to dc voltage regulator in the PolyPhase? series. A high-quality communication requires 1 channels.
