Descrizione

Traduzione AI

The LT8618 family are compact, high speed synchronous monolithic step-down switching regulators that deliver up to 100mA to the output with high efficiency at a constant frequency, even up to 2.2MHz. They accept a wide input voltage range up to 65V (transients only, 60V for continuous operation), and consume only 2.5μA of quiescent current when operating in Burst Mode. Top and bottom power switches are included with all necessary circuitry to minimize the need for external components. The LT8618C includes BST and INTVCC ceramic capacitors for a more compact solution while having SYNC/MODE and HYST pins. The SYNC/MODE pin selects the regulator’s operation between forced continuous mode, for predictive interference in sampling systems, Burst Mode, for increased efficiency at light loads or spread spectrum for Low EMI. It also allows synchronization to an external clock to further increase signal to noise ratio in high-resolution acquisition systems. A PG flag signals when VOUT is within ±7.5% of the programmed output voltage and when in fault conditions. Thermal shutdown provides additional protection.
