External Power Switch Boost
Linear Technology manufacturers a broad range of step-up (boost) controllers for virtually any application. These controllers offer wide input voltage ranges, multiple output capability, and can be configured for flyback, forward or SEPIC converters. Furthermore, they offer BurstMode operation for high efficiencies at light loads, easy synchronization to an external clock and have comprehensive protection features.
