Description
The JW®5231 is a current mode monolithic buckswitching regulator. Operating with an input rangeof 2.5V-5.5V, the JW5231 delivers 1.5A of continuous output current with integrated P-Channel and N-Channel MOSFETs. The internal synchronous power switches provide high efficiency. Current mode control provides tight load transient response and cycle-by-cycle current limit.
Features
-2.5V to 5.5V operating input range
- Up to 1.5A output current
- Up to 94% peak efficiency
- Internal Soft-Start-1.5MHz switching frequency
- Input under voltage lockout-Short circuit protection-Thermal protection-Hot-plug in protection-Output POK indication (available in SOT23-6package)-Available in SOT23-5/SOT23-6 package
Typical applications
- GPU/DDR Power Supply
- Storage Equipment, 5V or 3.3V Point of Load Conversion
- Set Top Boxes, Telecom/Networking Systems
