RT7250B - Synchronous Step-Down Converter

Download the RT7250B datasheet PDF. This datasheet also covers the RT7250A variant, as both devices belong to the same synchronous step-down converter family and are provided as variant models within a single manufacturer datasheet.

Description

The RT7250A/B is a high efficiency, monolithic synchronous step-down DC-DC converter that can operate at 340kHz/800kHz, while delivering up to 2A output current from a 4V to 17V input supply.

The RT7250A/B's current mode architecture allows the transient response to be optimized.

® RT7250A/B 2A, 17V, 340/800kHz Synchronous Step-Down Converter General Description The RT7250A/B is a high efficiency, monolithic synchronous step-down DC-DC converter that can operate at 340kHz/800kHz, while delivering up to 2A output current from a 4V to 17V input supply. The RT7250A/B's current mode architecture allows the transient response to be optimized. 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 voltage protection and thermal shutdown. The low current (<5μA) shutdown mode provides output disconnection, enabling easy power management in battery-powered systems.
