SI-8000JDseries is a chopper type switching regulator IC, incorporating various features and protection functions needed for a step-down switching regulator.Switching regulator with high precision and high efficiency can be constructed with only 4 discrete components.
Feature
- Surface-mount（TO263-5） package
- Output current: ：1.5A
- High efficiency: 77～88%
- 4 external components
- Internally-adjusted phase compensation and output voltage
- Capable of downsizing a choke-coil due to the IC's high switching frequency (Compared with conventional Sanken devices)
- Built-in foldback-overcurrent and thermal protection circuits
- Output ON/OFF available (circuit current at output OFF: 200μAmax）
- Soft start available by ON/OFF
Applications
- Power supply for telecommunication equipment
- On-board local power supply
