Overview
® RT7237A 2A, 18V, 340kHz Synchronous Step-Down Converter General Description The RT7237A is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 2A output current from a 4.
5V to 18V input supply.
The RT7237A's current mode architecture and external compensation allow the transient response to be optimized over a wide input range and loads.
Cycle-bycycle current limit provides protection against shorted outputs, and soft-start eliminates input current surge during start-up.
The RT7237A also provides under voltage protection and thermal shutdown protection.
The low current (<3 μ A) shutdown mode provides output disconnection, enabling easy power management in battery-powered systems.
The RT7237A is available in an SOP-8 (Exposed Pad) package.
