LT8253/LT8253A 40V USB Type-C Power Delivery Buck-Boost Controller FEATURES DESCRIPTION n Proprietary Low-EMI Buck-Boost Architecture The LT 8253/LT8253A are synchronous 4-switch buck- n Wide Input Range: 4V to 40V boost controllers optimized for automotive USB-C power n Synchronous Switching: Up to 98% Efficiency delivery. The LT8253/53A are fully compliant to the USB n 1.5% Output Voltage Regulation Power Delivery (PD) specification when used in conjunc- n Single Output supports 1 Type-C Port up to 100W tion with a USB Type-C or PD port controller. The output n Output Channel Enable Function voltage slew rate can be controlled through the FB pin. n Programmable Switching Frequency with External The LT8253 can deliver up to 100W output power with Synchronization and Spread Spectrum 98% peak efficiency when running below the AM band. n Over-Current, Over-Voltage, Short-Circuit Protection The LT8253A can deliver up to 60W output power with n Available in 28-Lead Side Solderable QFN Package 95% peak efficiency when running above the AM band. n AEC-Q100 Qualification in Progress The LT8253/8253A support single buck-boost output for 1 Type-C port with power good flag. Over-current, over- voltage, and short-circuit protections are also available.
