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
