The PCB layout plays an important role in the improvement of the MAX17504 heat dissipation and efficiency. Under normal conditions, a 4-layer PCB dissipates heat better than a 2-layer PCB, and a PCB with…
The loop-gain crossover frequency, where the loop gain equals 1 (0dB) should be set below 1/10th of the switching frequency
Choosing a lower crossover frequency reduces the effects of noise pick-up into…
LIR is the ratio of inductor peak-to-peak AC current to DC average current (LIR) first. For LIR values which are too high, the RMS currents are high, and therefore I2R losses are high. Use high-valued…
During 100% load step test in the EVKIT i.e. 3.2A‐>0A load transition, output voltage does not recover to nominal steady state voltage after overshoot and stays at an elevated level, until the next load…
When Vout is higher than Vin, the high side MOSFET's body diode will turn on and the inductor current becomes negative. When the negative inductor current reaches the valley current limit threshold (-1…
