DESCRIPTION

The LT®8645S-2 synchronous step-down regulator features

Silent Switcher architecture designed to minimize

EMI emissions while delivering high efficiency at high

switching frequencies. This performance makes the

LT8645S-2 ideal for noise sensitive applications and

environments.

The fast, clean, low-overshoot switching edges enable

high efficiency operation even at high switching frequencies,

leading to a small overall solution size. Peak current

mode control with a 40ns minimum on-time allows high

step-down ratios even at high switching frequencies.

Burst Mode® operation enables ultralow standby current

consumption, pulse-skipping mode allows full switching

frequency at lower output loads, or spread spectrum

operation can further reduce EMI emissions.
