OB2105 High Performance Synchronous Buck Converter GENERAL DESCRIPTION OB2105 is a wide input voltage, high-efficiency, high performance synchronous-rectified buck converter. OB2105 utilizes soft driving technology to achieve good EMI performance. OB2105 also provide soft-start, VIN/VOUT over voltage protection, over temperature protection, and output short circuit protection with hiccup mode. The built-in multi-stage detection scheme effectively protects the device and system when the output hard short to ground. OB2105 is available in SOP-8 and SOT23-5 packages and required very few external components for operation. FEATURES  Wide 6V to 35V Operating Input Range  Synchronous Operating without External Schottky Diode.  Simplified External Device Requirement.  90.
