TPS54202DDCR (Texas Instruments) is a 2 A synchronous buck converter with a 4.5 V to 28 V input range and integrated MOSFETs, in a 6-pin SOT-23 package.

• 4.5 V to 28 V input · integrated 148 mΩ and 78 mΩ MOSFETs for 2 A continuous output current
• Fixed 500 kHz switching frequency · frequency spread spectrum to reduce EMI · advanced Eco-mode pulse skip
• 3 µA shutdown and 45 µA quiescent current · internal 5 ms soft start · internal loop compensation
• Overcurrent protection for both MOSFETs with hiccup mode, overvoltage protection and thermal shutdown
