Original SY7304DBC Marking VI7QH Boost IC on Hashboard S19j Pro, Hashboard S19 XP

VI7QH is a high efficiency, current-mode control Boost regulator. The device integrates a 120mΩ low RDS(ON) N-channel MOSFET for high efficiency. The fixed 1MHz switching frequency and internal compensation reduce external components size and count. The build in internal soft start circuit minimizes the inrush current at start-up.

Features

1. Wide input range: 3-33V
2. Maximum output voltage: 33V
3. 1MHz switching frequency
4. Integrated 120 mΩ RDS(ON) switch with 4A peak current capability
5. Internal soft-start
6. 0.6V±2% reference voltage
7. Cycle by cycle peak current limit
8. Over temperature protection
9. RoHS Compliant and Halogen Free
10. Compact package: DFN3×3-10

Applications

1. Portable Device
2. Battery Powered System
3. Networking cards powered from PCI or PCI-express slots
