LTC3868EUH#PBF Descrizione generale

The LTC3868EUH#PBF stands out as a high-performance dual step-down switching regulator controller, setting a new standard in power management solutions. By driving all N-channel synchronous power MOSFET stages, this controller ensures optimal performance and reliability in various applications. Its constant frequency current mode architecture allows for a phase-lockable frequency of up to 850kHz, making it highly versatile and adaptable to different operating requirements. Additionally, the LTC3868EUH#PBF is designed to reduce power loss and noise by operating the two controller outputs out of phase, providing clean and efficient power delivery
