GENERAL DEscriptION：

The is a constant frequency, 6-pin SOT23 current mode step-up converter intended for small,low power applications. 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
