LT8646S規(guī)格書詳情
GENERAL DESCRIPTION
The LT?8641A 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 side wettable
QFN, the monolithic construction 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 LT8641A 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 opendrain
PG pin signals when the output is in regulation.
The SYNC/MODE pin selects between Burst Mode, pulseskipping,
or spread spectrum mode, and also allows
synchronization to an external clock. Soft-start and
tracking functionality are accessed through 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.
