Model LT1959IR#PBF
Description Linear Technology **Linear Technology** Provide a series of step-down switching regulators with synchronous and asynchronous internal switches. They can provide input voltages ranging from 2.25V to 30V and multiple switching frequencies. They can be used for various applications such as distributed power supply systems, battery powered instruments, and load point power sources. ###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.
