SCM1302A High-Efficiency Wide Input-Voltage-Range 2A Buck Regulator Packaging Features           4.5V to 40V Input Range Output Current up to 2 A 100mΩ High-Side MOSFET Minimum On Time: 102ns Peak Current Mode Control Adjustable Switching Frequency from 200kHz to 1.5MHz Internal Soft-Start 2μA Shutdown Current Under-voltage Lockout, Over-current Protection, and Thermal Protection eSOP-8 Package Product Package: eSOP-8 (see “Ordering information” for details) Application     Automotive Battery Regulation Industrial Power Supplies Telecom and Datacom Systems Battery-Powered Systems Description The SCM1302A is a step-down regulator. With a wide input range 4.5 V to 40 V, it is suitable for a wide range of applications from industry to automotive. An ultra-low shutdown current(Typ=2μA) prolongs the battery life. A wide adjustable switching frequency range allows either efficiency or external component size to be optimized. Soft start is implemented internally, and this allows the device to be used with minimum external components . The SCM1302A is optimized for up to 2 A load current, and has a 0.75 V nominal feedback voltage. The device has built-in thermal protection and short protection, and is available in the eSOP-8 package(4.9mm × 6.0mm ×1.5mm).
