The Oceanside design includes a high-efficiency step-up controller, a 36V H-bridge transformer driver for isolated supplies, a wide input range, and adjustable output low-dropout linear regulator (LDO). Test results and hardware files are included.  Introduction Isolated power is required in many applications such as industrial and medical applications. The Oceanside design uses a step-up HYPERLINK /glossary/definitions.mvp/term/DC-DC-Controller/gpk/78 controller ( HYPERLINK /MAX668 MAX668), a 36V HYPERLINK /glossary/definitions.mvp/term/H-Bridge/gpk/155 H-bridge HYPERLINK /glossary/definitions.mvp/term/Transformer/gpk/1070 transformer driver ( HYPERLINK /MAX13256 MAX13256), and a pair of LDOs ( HYPERLINK /MAX1659 MAX1659 x2) to create a ±15V (±12V) output isolated power supply from a wide range of input voltages. This general purpose power solution can be used in many different types of isolated power applications, but is mainly targeted for industrial sensors, industrial automation, process control, and medical applications.
