AT6145 Datasheet | IAT

FEATURES Immense Advance Tech. DESCRIPTION up to 93% Efficiency Integrated 80mΩ Power MOSFET 2.3V to 24V Input Voltage 1.2MHz Fixed Switching Frequency Internal 4A Switch Current Limit Adjustable Output Voltage up to 28V Internal pensation Automatic Pulse Frequency Modulation Mode at Light Loads SOT26 Package Available APPLICATION Battery-Powered Equipment Set-Top Boxed LCD Display DSL and Cable Modems and Routers Networking cards powered from PCI SMPS Post-Regulator / DC-to-DC Modules High-Efficiency Linear Power Supplies or PCI express slots The AT6145 is a constant frequency, 6-pin SOT23-6L current mode step-up converter intended for small, low power applications. The AT6145 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 AT6145 features automatic shifting to pulse frequency modulation...
