Description
The MAX5073 includes an internal digital soft-start that reduces inrush current, eliminates output-voltage overshoot, and ensures monotonic rise in output voltage during power-up. The device includes individual shutdown and a power-good output for each converter. Protection features include output short-circuit protection for buck mode and maximum duty-cycle limit for boost operation, as well as thermal shutdown.
The MAX5073 is available in a thermally enhanced 28-pin thin QFN package that can dissipate 2.7W at +70°C ambient temperature. The device is rated for operation over the -40°C to +85°C extended, or -40°C to +125°C automotive operating temperature range.
