SEPIC Regulators

Analog Devices manufacturers a broad range of monolithic boost switching regulators that can be configured as SEPIC converters. These SEPIC converters maintain a fixed output voltage regardless of whether the input voltage is above, or below the input. These converters offer wide input voltage ranges, internal Schottky diodes, and external synchronization. Other features include programmable current limit, burst-mode operation, and low battery detect.
