Description
The RP510 is a step-down DCDC converter that operates the low input voltage of 2.5 V to 5.5 V. The RP510 being suitable for power supply of SoC (System-on-chip) can be output to 4 A (Max.). And, the foldback type protection, which be released automatically from the overcurrent protection, is user-selectable. This product for industrial applications are characterized to -50°C, and operates in a wide temperature range from low temperature to high temperature.
Key Benefits
- The realization of the high-density mounting by the adoption of a small package DFN3030-12
- A simplification of the power sequencing by power-good and adjustable soft-start functions
- Selectable overcurrent protection: Latch type or Foldback type
