SLVSCW4B April 2016 – May 2019 TPS560200-Q1
When the TPS560200-Q1 is in the normal CCM operating mode and the switch current falls to 0 A, the TPS560200-Q1 begins operating in pulse-skipping Eco-Mode. Each switching cycle is followed by a period of energy-saving sleep time. The sleep time ends when the VFB voltage falls below the Eco-Mode threshold voltage. As the output current decreases the perceived time between switching pulses increases.
