LTC3899EFE#PBF Overview
This switching controller fits most application requirements since it is packaged in a 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package. dc motor controller is suitable for 3 output generation. An enclosure of Tube is used to package the PMIC. Transistor Driver dc switching's outputs (s) can be handled by it. Voltages 4.5V~60V are the dc control's supply voltage and operating voltage, respectively. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. In this switching controller, the switch can be set to 105kHz~835kHz 350kHz~535kHz. dc dc regulators can be carried out with Surface Mount. Enable, Frequency Control, Soft Start, Tracking provides dcdc regulator efficient switching control. You can find other relevant dc to dc converter ics by searching "LTC3899". Total pins of switching converter are 38. The duty cycle of the voltage regulator dc to dc can be set to 100 % on power-up or power-down to ensure reliability.
