TPS62A02: Switching frequency for PSM, PWM

Jason Chen

Prodigy 10 points

Part Number: TPS62A02

Tool/software:

Hi,

Currently, we are designing the circuitry for a PCIe Gen5 SSD and are looking for components for power management.
From the TPS62A02 datasheet, we noticed that PSM and PWM modes seem to lack information on the switching frequency. However, we found relevant diagrams in the datasheet of other components, such as the TLV62568PDRLR. Could you let us know if there are similar diagrams available for the TPS62A02 for reference?

Figure 1. Switching Frequency from TLV62568DRLR datasheet

Thank you very much.

Hi Jason,

thanks for using E2E.

Could you please provide the VIN and VOUT voltages you are interested in. Your are planning to use the TPS62A02 (PSM) or the TPS62A02A (FPWM)?

Best regards,
Sepp

Hi Josef,

Our Vin/Vout voltages are 3.3V/1.8V, and we're planning to use TPS62A02 (PSM).

Thank you very much.
Best regards,
Jason

Hi Jason,

here the frequency behavior in PSM at VIN=3.5V (similar to 3.3V) and VOUT=3.3V.

Best regards,
Sepp
