TPS54202DDCR Description

The TPS54202 is a 2-A synchronous buck converter with a 4.5-V to 28-V input voltage range. To reduce component count, the device has two integrated switching FETs, internal loop correction, and a 5-ms internal soft start. The TPS54202 achieves a high power density and a small PCB footprint by integrating the MOSFETs and using the SOT-23 packaging. Advanced Eco-mode implementation improves light load efficiency while lowering power consumption. For EMI reduction, the frequency spread-spectrum operation is used.
