TPS54821RHLR General Description
Safety is a top priority with the TPS54821RHLR, as it incorporates cycle by cycle current limiting on the high-side FET to protect against overload situations. The low-side sourcing and sinking current limits work together to prevent current runaway and excessive reverse current, ensuring reliable operation in challenging conditions. In the event of prolonged overcurrent or thermal issues, the device activates a hiccup protection mechanism to safeguard against damage

Features
- The TPS54821RHLR supports 4-17V input voltage range and up to 8A output current
- This device offers adjustable switching frequency from 50kHz to 2.5MHz for optimal performance
- TPS54821RHLR integrates soft-start, UVLO and thermal shutdown features for safe operation

Application
- High power density
- Common in industrial equipment
- Reliable point-of-load converter
