SY8003ADFC DC-DC power chip step-down for Antminer S19 Pro hashboard repair
SY8003ADFC is a high-efficiency, high-frequency synchronous step-down DC-DC regulator IC on the S19PRO hash board, capable of delivering up to 3A of output current, and is silk-screen marked KW***. It operates over a wide input voltage range of 2.7V to 5.5V and integrates a main switch and a synchronous switch with very low RDS(ON) to minimize conduction losses. Its 1MHz switching frequency enables low output voltage ripple and small external inductor and capacitor sizes.
Feature:
• Low RDS(ON) for internal switches (top/bottom): 110mΩ/80mΩ
• 3A continuous load current capability
• 2.7-5.5V input voltage range
• High switching frequency minimizes external components: 1MHz
• Internal soft-start limits inrush current
• Reliable short circuit protection
• Reliable overvoltage protection
• 100% exit operation
• RoHS-compliant and halogen-free
