The 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 features automatic shifting to pulse frequency modulation mode at light loads. The includes under-voltage lockout, currentlimiting, and thermal overload protection to prevent damage in the event of an output overload. The is available in a small 6-pin SOT-23 package. 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 97% 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
