LTC3855EFE#PBF Descrizione generale

The LTC3855EFE#PBF is a versatile dual PolyPhase^® current mode synchronous step-down switching regulator controller designed to drive all N-channel power MOSFET stages with precision and efficiency. With its high speed differential remote sense amplifier, this controller ensures accurate voltage regulation and reliable performance in a range of applications. What sets this product apart is its programmable maximum current sense voltage, which can be set to 30mV, 50mV, or 75mV, allowing for flexibility in selecting the sensing element, whether it be the inductor DCR or a discrete sense resistor. This level of adaptability makes the LTC3855EFE#PBF a practical choice for power management designs that demand precision and customization
