n AEC-Q100 Qualification in Progress The LT®8253/LT8253A are synchronous 4-switch buck
boost controllers optimized for automotive USB-C power
delivery. The LT8253/LT8253A are fully compliant to the
USB power delivery (PD) specification when used in conjunction with a USB Type-C or PD port controller. The output voltage slew rate can be controlled through the FB pin.
The LT8253 can deliver up to 100W output power with
98% peak efficiency when running below the AM band.
The LT8253A can deliver up to 60W output power with
95% peak efficiency when running above the AM band. n All registered trademarks and trademarks are the property of their respective owners. TYPICAL APPLICATION
