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.
