OB2105
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.
