Model LTC3891EUDC#PBF
Description Linear Technology **Linear Technology** Provide a range of low-power single-chip step-down converters designed for applications that require increased efficiency at low loads. These devices generate low standby static current in burst mode. They can be used for applications such as high-voltage power conversion, battery power supply, automotive, distributed power supply, and industrial power systems. ###Switching voltage regulator, Linear Technology's synchronous and asynchronous internal switching regulator IC product series has high efficiency, wide input voltage range, and switching frequency up to 4 MHz. This series of controllers includes various configurations, including step-down (down), step-up (up), step-down step-up, forward, isolated, reverse, and flyback controllers. The flyback, forward, and isolation controllers (primary and secondary) provide solutions to assist in the replacement of DC/DC brick converters used in backplane power conversion.
