A 60° phase margin is a good result. A faster response to current load changes is achieved when the bandwidth (BW) of the power supply design is wider. The BW of the power supply is where the 0 dB gain crosses the frequency axis. Also known as the crossover f...
A contractor that underestimates the cost of a project could be forced to cut into their own profit margin to cover project costs. On the other hand, overestimating the actual project costs could lead a contractor to submit a bid that’s too high to be selected. Even in negotiated bidding...
Loop response - IOUT = 10 A, Loop Bandwidth = 120 kHz, Phase Margin = 65° 3.3.9 Output Voltage Ripple Figure 3-7 shows an output voltage ripple of 12.1 mV with a load of 0 A. Figure 3-8 shows an output voltage ripple of 12.1 mV with a load of 10 A. 12 TPS542A50 SWIFT...
Initially, the output sags al- most 200mV due to slow loop response time (the R1-C1 pair delay VC pin (Trace B) response). When the LT1074 comes on response is reasonably quick and surprisingly well behaved considering circuit dynamics. The multi-time constant recovery7 ("rattling" is ...
which were tuned according to the conventional criteria of phase and gain margin (0.25𝑓𝑠≤𝑓𝑐≤10𝑓𝑠0.25fs≤fc≤10fs and 45≤𝑃𝑀≤9045≤PM≤90) to provide a good response with adequate output voltage overshoot and ensures the stability of the converters during the load st...
Variable step size algorithms allow the filters to dynamically adjust their performance in response to conditions in the input data and error signals. In this context, one of the most popular algorithms is the variable step size LMS (VSLMS) proposed in [170]. In the VSLMS algorithm, each ...
6.3 Control Loop Gain and Phase Measurement Procedure The TPS546B24AEVM-1PH includes a 100.0-Ω series resistor in the feedback loop for VOUT. The resistor is accessible at the test points TP16 and TP17 for loop response analysis. These test points should be used during loop response ...

Current-mode control provides fast transient response and cycle-by- cycle current limit. An adjustable soft-start prevents inrush current at turn-on, and in shutdown mode the supply current drops to 0.1µA. Built-in output over voltage (open load), over temperature, cycle-by-cycle over ...
