TPS562208DDCR
The TPS562208 is a 2A synchronous buck regulator with integrated FETs using D-CAP2 control for fast transient response. It accepts 4.5V to 17V input, produces 0.76V to 7V output, and operates in forced-PWM (FCCM) mode. It features internal soft-start, over-current and thermal protection, and is specified from -40C to 125C.
