3.3 V/1.0 A Buck Regulator
DescriptionThe CS51411 demonstration board is a 1.0 A/3.3 V buck
regulator running at 260 kHz (CS51411) or 520 kHz
(CS51413). The switching frequency can be synchronized to
a higher frequency through feeding clock signals to the SYNC
input. Driving SHDNB input low shuts down the converter
output and minimizes the power consumption. The regulator
has superior line and load regulation due to the use of V2
control. This control method also enhances the load transient
response.
Features V2 Control for Superior Line and Load Regulation Small Board Space Requiring Only 1.0 × 0.7 in. Total of 11 Components Including IC Shutdown Mode Disables the Output and Reduces the
Operating Current Frequency Synchronization to Higher Frequency 1.5 A Peak Current Protection which Folds Back 30%
During Overload Conditions Built–In Soft Start to Eliminate Any In–Rush Current High Energy Transfer Efficiency of 83% at 1.0 A Load Line Regulation Better Than 0.1% Load Regulation Better Than 0.4%
