ZHCSQS6C November 2007 – January 2024 TPS5420-Q1
PRODUCTION DATA
The TPS5420 has an OVP circuit to minimize voltage overshoot when recovering from output fault conditions. The OVP circuit includes an overvoltage comparator to compare the VSENSE pin voltage and a threshold of 112.5% × VREF. Once the VSENSE pin voltage is higher than the threshold, the high-side MOSFET is forced off. When the VSENSE pin voltage drops lower than the threshold, the high-side MOSFET is enabled again.
