LTC7840EFE#TRPBF Overview
Capsuled in the 28-TSSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller suits most application needs. 2 outputs are supported by the dc motor controller. A solid enclosure of Tape & Reel (TR) surrounds pmic. With PWM dc switching's output (s), it is able to handle it. This dc control operates at 5.5V~60V and has a 5.5V~60V supply voltage. A -40°C~125°C TJ dc switcher is not a problem. Using this switching controller, it is possible to switch at 50kHz~425kHz. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Frequency Control, Power Good.
