RT8295BHZSP

DC-DC开关降压 降压稳压器, 可调, 4.5V至23V输入, 0.8V-15V/2A输出, SOP-8

The from is a 2A, 23V, 1.2MHz synchronous step-down converter in 8 pin SOP package. It is a high-efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 2A output current from a 4.5V to 23V input supply. The RT8295B"s current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up. The RT8295B also provides under voltage protection and thermal shutdown protection. The low current <3µA shutdown mode provides output disconnection, enabling easy power management in battery-powered systems. It is used in wireless AP/router, set-top-box, LCD monitors and TVs, green electronics/appliances and point of load regulation of high-performance DSPs.
