DC-DC开关降压 降压稳压器, 可调, 4.5V至18V输入, 2A输出, 500 kHz, TSOT-23-6

The from is a 2A, 18V, 500KHz, ACOT step-down converter in 6 pin TSOT-23 package. This is a high-efficiency, monolithic synchronous step-down DC-DC converter that can deliver up to 2A output current. It adopts ACOT architecture to allow the transient response to be improved and keep in constant frequency. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up. Fault conditions also include output under-voltage protection, output over-current protection and thermal shutdown. It is used in set-top boxes, portable TVs, access point routers, DSL modems and LCD TVs.
