DESCRIPTION

The LT®8641 step-down regulator features Silent Switcher architecture designed to minimize EMI emissions while

delivering high efficiency at frequencies up to 3MHz. assembled in a 3mm × 4mm QFN, the monolithic con-struction with integrated power switches and inclusion of all necessary circuitry yields a solution with a minimal PCB footprint. An ultralow 2.5µA quiescent current—with the output in full regulation—enables applications requiring highest efficiency at very small load currents. Transient response remains excellent and output voltage ripple is below 10mVP-P at any load, from zero to full current. The LT8641 allows high VIN to low VOUT conversion at high frequency with a fast minimum top switch on time of 35ns. 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/MODE pin selects between Burst Mode, pulse skipping, or spread spectrum mode, and also allows syn-chronization to an external clock. 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.
