PRODUCTION DATA
The controller device TPS59632-Q1 does not require any additional loop compensation for stability as the load-line setting droop amplifier gain automatically stabilizes the DCAP+ control loop. However, to further increase the response time to fast load transients, an additional resistor (3 kΩ) in series with a capacitor (560 pF) is placed from COMP to VREF. Frequency response is measured to ensure the stability while meeting the transient requirements. Some key results for this design are given in Section 8.2.1.3.
