Description

This is High Efficiency 1.2MHz 2A Step Up Converter. SX1308 High Efficiency 1.2MH- 2A Step U85pTConverter 85T FEATURES Integrated 80mΩ Power MOSFET 2V to 24V Input Voltage 1.2MH- 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 1.2MH- 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 .
