Description

General part information

LT8648S Series

The LT8648S 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 input and boost capacitors to optimize all the fast current loops inside and make it easy to achieve advertised EMI performance by reducing layout sensitivity. This performance makes the LT8648S 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 on-time allows high step down ratios even at high switching frequencies. External compensation via the VCpin allows for fast transient response at high switching frequencies. The VCpin also enables current sharing and a CLKOUT pin enables synchronizing other regulators to the LT8648S.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 via the SS pin, and an accurate input voltage UVLO threshold can be set using the EN/UV pin.APPLICATIONSAutomotive and Industrial SuppliesGeneral Purpose Step-DownAll registered trademarks and trademarks are the property of their respective owners.
