DESCRIPTION

The LT?8645S/LT8646S synchronous step-down regulator

features second generation Silent Switcher architecture

designed to minimize EMI emissions while delivering high

efficiency at high switching frequencies. This includes the

integration of bypass capacitors to optimize all the fast

current loops inside and make it easy to achieve advertised

EMI performance by eliminating layout sensitivity.

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. The

LT8646S has external compensation to enable current

sharing and fast transient response 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.
