RT7257B
3A, 18V, 1.2MHz Synchronous Step-Down Converter
General Description
The RT7257B is a high efficiency, monolithic synchronous
step-down DC/DC converter that can deliver up to 3A
output current from a 4.5V to 18V input supply. The
RT7257B's current mode architecture and external
compensation allow the transient response to be
optimized over a wide input voltage range and loads.
Cycle-by-cycle current limit provides protection against
shorted outputs, and soft-start eliminates input current
surge during start-up. The RT7257B also provides under
voltage protection and thermal shutdown protection. The
low current (
