产品概要
描述
The STEVAL-ISA202V1 product evaluation board provides a platform for evaluation of the L4971, a 1.5 A asynchronous step-down power switching regulator with zero load current operation capability.
Based on the selection of the external components, the device can operate in the entire input voltage range of 8 V < VIN < 55 V. The output voltage is limited by the voltage rating of the output capacitor, so it can be adjusted within the 3.3 V < VOUT < 30 V range through voltage divider R2, R3.
The input and output capacitors are capable of sustaining the RMS current within the operating range.
