- Synchronous rectification circuitry
with Leonard Shtargot Staff Engineer, Power Products
The LT®8610 step-down regulator integrates key high performance features in one compact IC. It offers synchronous rectification, for efficiencies up to 96%. The low quiescent current of 2.5µA extends battery life and saves extra circuitry.
High speed switching minimizes board space and helps avoid EMI problems. A low dropout of 200mV at 1A load allows wide VIN range. The LT8610 is a great choice for many step-down applications requiring high input voltages up to 42V and load currents up to 2.5A.
