General Description

The RT7298A 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 RT7298A

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.
