Other Parts Discussed in Thread: LMR38020
Hello, i am reading the datasheet of LMR38020 and i find that LMR38020 has TWO FUNCTIONAL MODES: Auto Mode, where the device can move between PWM and PFM as the load changes, and FPWM Operation. So i am wondering how the device choose its functional modes and determine whether the load is light or not. If the chip code is LMR38020FSDDAR, does it mean that this device can only operate on FPWM mode? Also how can i know whether the device realizes the function of spread spectrum?
I am looking forward to hear from you. Thank you!
