Can I toggle the TPS62110 SYNC pin to switch from forced PWM mode to PWM/PFM mode and back during operation
The SYNC pin can be toggled high or low while the device is in operation without any problems. I have attached a scope capture showing the behavior of our EVM when switching SYNC from low (PFM mode) to high (PWM mode). Test conditions: Vin = 5V, Vout = 3.3V, Iout = 10mA.
