简  介:Shouding 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 SDB628 High Efficiency 1.2MHz 2A Step Up Converter GENERAL DESCRIPTION SDB628 is a constant frequency, 6-pin SOT23 The SDB current mode step-up converter intended for small, low power applications. The SDB628 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 SDB628 features automatic shifting to pulse frequency modulation mode at light loads. The SDB628 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The SDB628 is available in a small 6-pin SOT-23 package.
