GENERAL DESCRIPTION
The LT?8638-2 synchronous step-down regulator
features the Silent Switcher? architecture designed to
minimize EMI emissions while delivering high efficiency
at high switching frequencies. This performance makes
the LT8638-2 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 25ns minimum ontime
allows high step down ratios even at high switching
frequencies. External compensation through the VC pin
allows for fast transient response. PolyPhase operation
allows multiple LT8638-2 regulators to run with
interleaving phase shift to provide more output current.
Burst Mode operation enables low standby current
consumption, forced continuous mode can control
frequency harmonics across the entire output load
range, or spread spectrum operation can further reduce
EMI emissions. Soft-start and tracking functionality is
accessed through the SS pin, and an accurate input
voltage UVLO threshold can be set using the EN/UV pin.
