LT3680
36V, 3.5A, 2.4MHz
Step-Down Switching Regulator
with 75µA Quiescent Current
FEATURES DESCRIPTION Wide Input Voltage Range: 3.6V to 36V
■ 3.5A Maximum Output Current
®
■ Low Ripple (30V), the saturation current should be above 5A.
To keep the efficiency high, the series resistance (DCR)
should be less than 0.1 , and the core material should
be intended for high frequency applications. Table 1 lists
several vendors and suitable types.
