Product Summary

The MAX1921EUT15+T step-down converter delivers over 400mA to outputs as low as 1.25V. The MAX1921EUT15+T uses a unique proprietary current-limited control scheme that achieves over 90% efficiency. The MAX1921EUT15+T maintains extremely low quiescent supply current (50μA), and its high 1.2MHz (max) operating frequency permits small, low-cost external components. This combination makes the MAX1921 an excellent high-efficiency alternative to linear regulators in space-constrained applications.
