RT7252A/B

2A, 17V, 340/800kHz Synchronous Step-Down Converter

General Description

Features

^z4V to 17V Input Voltage Range

The RT7252A/B is a high efficiency, monolithic

synchronous step-downDC/DC converter that can operate

at 340kHz/800kHz, while delivering up to 2A output current

from a 4V to 17V input supply. The RT7252A/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. The

RT7252A/B is available in a SOP-8 (Exposed Pad)

package.
