When the adaptive peak current is enabled, the device adjusts the peak inductor current setting automatically based on the load condition. Here is the effect on the switching frequency when it’s disabled…
The MAX14745 Buck regulators feature a variable frequency mode for increased efficiency during light-load operation. However, there is a feature where pulse frequency modulation can be switched to peak…
Page 8 and 9 of the datasheet give a typical value of switching frequency as 3MHz. However, it's not the switching frequency itself but the frequency of the burst pulses that causes the issue of noise…
The MAX14745 is not like a traditional buck converter where the device mode depends on the load and switches between PWM and PFM (Burst) modes automatically. In these PMICs you have to select either one…
Yes, MAX14745 do not include watch dog function, but it can add a watch dog through pFN1(hard reset) & pFN2(soft reset) pin. Customer can connect a watch dog reset output to pFN1 or pFN2, so the PMIC can…
The MAX14690 and the MAX14745 are very close devices. The main difference is an improved buck architecture in the MAX14745 to improve EMI performance. It has additional features to control the noise spectrum…
