LT3791EFE-1#PBF

LINEAR TECHNOLOGY  LT3791EFE-1#PBF  控制器, PWM 降压-升压, 700 kHz, 10A输出, TSSOP-38

The is a 60V 4-switch Synchronous Buck-Boost Controller regulates output voltage, output current or input current with input voltages above, below or equal to the output voltage. The constant-frequency, current mode architecture allows its frequency to be adjusted or synchronized from 200 to 700kHz. No top FET refresh switching cycle is needed in buck or boost operation. With 60V input, 60V output capability and seamless transitions between operating regions, the LT3791-1 is ideal for voltage regulator, battery/ super-capacitor charger applications in automotive, industrial, telecom and even battery-powered systems. It provides input current monitor, output current monitor and various status flags, such as C/10 charge termination and shorted output flag.
