LT3791IFE#PBF

LINEAR TECHNOLOGY  LT3791IFE#PBF  发光二极管驱动器, 1输出, 降压-升压, 4.7V-60V输入, 700kHz开关, 60V/10A输出, TSSOP-38

The is a synchronous 4-switch buck-boost LED Driver Controller can regulate LED current up to 52V of LED string with input voltages above, below or equal to the output voltage. The constant-frequency, forced-continuous current mode architecture allows its frequency to be adjusted or synchronized from 200 to 700kHz. No top MOSFET refresh switching cycle is needed in buck or boost operation. With 60V input, 60V output capability and seamless transitions between operating regions. The LT3791 provides input current monitor, LED current monitor and open or shorted LED fault condition, during which the LT3791 either restarts or latches off.
