LT8610ABHMSE#PBF

直流-直流开关降压稳压器, 可调, 3.4 V-42 V输入, 970 MV-39.7 V/3.5 A输出, 2.2MHZ, MSOP-16

The from is a 42V, 3.5A synchronous step-down regulator with 2.5µA quiescent current in 16 pin MSOP package. This compact, high efficiency, high speed synchronous monolithic step-down switching regulator consumes only 2.5µA of quiescent current. Compared to the LT8610, the LT8510AB has higher maximum output currents of 3.5A and faster minimum switch-on time of 30ns. The LT8610AB has even higher light load efficiency than LT8610. A SYNC pin allows synchronization to an external clock. The EN/UV pin has an accurate 1V threshold for VIN undervoltage lockout or shut down. A capacitor on the TR/SS pin programs the output voltage ramp rate during start-up. The PG flag signals when VOUT is within ±9% of the programmed output voltage as well as fault conditions.
