RT8250

3A, 23V, 340kHz Synchronous Step-Down Converter

General Description

Features

^ꢀ4.5V to 23V Input Voltage Range

The RT8250 is a high-efficiency synchronous step-down

DC/DC converter that can deliver up to 3Aoutput current

from 4.5V to 23V input supply. The RT8250's current mode

architecture and external compensation allow 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 start-up. The RT8250 also

provides output under voltage protection and thermal

shutdown protection. The low current (<3μA) shutdown

mode provides output disconnection, enabling easy power

management in battery-powered systems.
