Features & Applications
The SC4530WLTRT is a micropower hysteretic current-mode step-down switching regulator capable of providing up to 300 mA of output current from 3 V to 30 V input voltage range. It is designed to provide very high standby efficiency while simplifying design.
Features:
- Input Voltage Range: 3 V to 30 V
- Low Quiescent Current: Drawing 19mA from VIN when Stepping Down from 12 V to 3.3 V at No Load
- High Efficiency from 12 V Input to 5 V Output
- > 80% at 650 mA
- > 85% at 10 mA - 300 mA
- Up to 300 mA Continuous DC Output Current
- Integrated Power Switch and Schottky Diodes
- Low Output Ripple
- < 1mA Shutdown Current
- Hysteretic Current-Mode Control
- Cycle-by-Cycle Current Limiting
- Alternating Between Micropower Idling and Switching States at Light Loads to Conserve Power
- Output Short-Circuit Protection
- Solution Footprint as Small as 50 mm2
- Low-Profile 3 mm x 2 mm MLPD 8-Lead Package
Applications:
- Portable Equipment
- Notebook Computers
- Distributed Supplies
- Backup Power Supplies
