产品概述

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.

  • 所有功能

    • Input voltage range: 8 V to 55 V
    • Output voltage: 5.1 V ± 3% (line, load and thermal)
    • Output ripple: less than 51 mV
    • Output current range: up to 1.5 A
    • Max output ripple current: 30%
    • Current limit: 2.5 A typ.
    • Switching frequency: 200 kHz
    • RoHS compliant
