Analog Devices Inc. LT8253 and LT8253A USB Type-C™ Buck-Boost Controllers offer synchronous 4-switch power-optimized for automotive USB-C power delivery. The controllers comply with the USB Power Delivery (PD) specification when used in conjunction with a USB Type-C or PD port controller.
The ADI LT8253 and LT8253A USB Type-C Buck-Boost Controllers can control the output voltage slew rate through the FB pin. The LT8253 delivers up to 100W output power with 98% peak efficiency when running below the AM band. Meanwhile, the LT8253A provides up to 60W output power with 95% peak efficiency when running above the AM band.
The LT8253 and LT8253A enable a single buck-boost output for 1 Type-C port with a power good flag. The devices support over-current, overvoltage, and short-circuit protections.
