ZHCSHN7B February 2018 – April 2018 TPSM84624
PRODUCTION DATA.
The TPSM84624 transient response is listed in Table 8 for several common output voltages with different capacitor combinations. The calculated RTT value is included in the table along with the typical voltage deviation for a 1.5 A and 3 A load step. All data was taken at the recommended switching frequency for each output voltage.
