The RT7243 is a high efficiency, monolithic synchronous
step-down DC/DC converter that can deliver up to 6A output
current from a 4.5V to 18V input supply. The RT7243
current-mode architecture with external compensation
allows 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 startup.
Fault condition protections include output under-voltage
protection, output over-voltage protection, and overtemperature
protection. The low current shutdown mode
provides output disconnection, enabling easy power
management in battery-powered systems.资料下载
