Hello,
I may use this TPS22992 switch for powering a LTE modem.
VCC = VBIAS = 3.8V
I'm wondering about the frequency of the chargepump. I have an analog section in the product that would be very sensitive to noise frequencies between 8 and 20kHz. Usually chargepumps are considered as noisy devices and often operates in this frequency range, but what about this small integrated charge pump ? What would be its frequency in steady ON state ?
Thank you
Aurelien
