Overview
SX1308 High Efficiency 1.
2MHz 2A Step U85pTConverter 85T FEATURES • Integrated 80mΩ Power MOSFET • 2V to 24V Input Voltage • 1.
2MHz Fixed Switching Frequency • Internal 4A Switch Current Limit • Adjustable Output Voltage • Internal Compensation • Up to 28V Output Voltage • Automatic Pulse Frequency Modulation Mode at Light Loads • up to 96% Efficiency • Available in a 6-Pin SOT23-6 Package APPLICATIONS • Battery-Powered Equipment • Set-Top Boxed • LCD Bais Supply • DSL and Cable Modems and Routers • Networking cards powered from PCI or PCI express slots GENERAL DESCRIPTION The SX1 308 is a constant frequency, 6-pin SOT23 current mode step-up converter intended for small, low power applications.
The SX1308 switches at 1.
2MHz and allows the use of tiny, low cost capacitors and inductors 2mm or less in height.
Internal soft-start results in small inrush current and extends battery life.
The SX1308 features automatic shifting to pulse frequency modulation mode at light loads.
The SX1308 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload.
The SX1308 is available in a small 6-pin SOT-23 package.
