Introduction
The LT8653S is a dual step-down regulator that delivers up to 2A of continuous current from both channels and supports loads up to 3A from each channel. The LT8653S features the second generation Silent Switcher architecture to minimize EMI emissions while delivering high efficiency at high switching frequencies. This includes integration of bypass capacitors to optimize high frequency current loops 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 solution size with wide control loop bandwidth for fast transient response. Burst Mode operation enables ultralow standby current consumption or forced continuous mode can be used to control frequency harmonics across the entire output load range. The LT8653S is a full featured, customizable voltage regulator, but also has several pin strap options to select internal 2MHz switching frequency, internal compensation and internal feedback resistor divider options to create a simple, compact two output voltage regulator with only five external components.
