JAJSQB9 January 2024 TPS56A37
PRODUCTION DATA
The TPS56A37 requires an input decoupling capacitor and a bulk capacitor is needed depending on the application. TI recommends a ceramic capacitor over 10µF for the decoupling capacitor. TI recommends an additional 0.1µF capacitor (C3) from VIN to PGND pin to provide additional high frequency filtering. The capacitor voltage rating must be greater than the maximum input voltage. The input voltage ripple can be calculated using Equation 12.
The capacitor must also have a ripple current rating greater than the maximum input current ripple of the application. The input ripple current is calculated by Equation 13:
