Datasheet Linear Technology LT3980HMSE#PBF — Ficha de datos

LT3980
58V, 2A, 2.4MHz
Step-Down Switching Regulator
with 85µA Quiescent Current
Features Description Wide Input Range: Operation from 3.6V to 58V
■ Overvoltage Lockout Protects Circuits Through 80V
Transients
■ 2A Maximum Output Current
®
■ Low Ripple (40V), the saturation current should
be above 3.5A. To keep the efficiency high, the series
resistance (DCR) should be less than 0.1Ω, and the core
material should be intended for high frequency applications.
