LT8640SIV#PBF (LINEAR TECHNOLOGY)

The LT8640SIV#PBF from Linear Technology is a 42V, 6A synchronous step-down silent Switcher 2 with 2.5µA quiescent current in 24 pin LQFN package. The LT8640S synchronous step-down regulator features second generation Silent Switcher 2 architecture designed to minimize EMI/EMC emissions while delivering high efficiency at high switching frequencies. It is ideal for noise sensitive applications and environments. Peak current mode control with a 30ns minimum on-time allows high step-down ratios even at high switching frequencies. Burst mode operation enables ultralow standby current consumption, forced continuous mode can control frequency harmonics across the entire output load range, or spread spectrum operation can further reduce EMI/EMC emissions. Soft-start and tracking functionality is accessed via the TR/SS pin and an accurate input voltage UVLO threshold can be set using the EN/UV pin. A CLKOUT pin enables synchronizing other regulators to the LT8640S.
