Analog Devices LT8253 | Demoboard DC3004A

Description

The LT8253/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.The LT8253/LT8253A 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.
