LT8614IUDC#TRPBF

LT8614 is a step-down regulator features Silent Switcher architecture designed to minimize EMI emissions while delivering high efficiency at frequencies upto 3MHz. This device allows high VIN to low VOUT conversion at high frequency with a fast minimum top switch on-time of 30ns. Operation is safe in overload even with a saturated inductor. Essential features are included and easy to use: An open drain PG pin signals when the output is in regulation. The SYNC pin allows clock synchronization and choice of Burst Mode operation or pulse-skipping mode. Soft-start and tracking functionality is accessed via the TR/SS pin. An accurate enable threshold can be set using the EN/UV pin and a resistor at the RT pin programs switch frequency. It is widely used in application such as n automotive and industrial supplies, general purpose step-down, GSM power supplies etc.
