PRODUCTION DATA.
The TPSM842xx devices operate in Eco-mode operation in light load conditions. Eco-mode is a high-efficiency, pulse-skipping mode under light load conditions. Pulse skipping initiates when the switch current falls to 840 mA typically. During pulse skipping, the low-side FET turns off when the switch current falls to 0 A. The device takes on the characteristics of discontinuous conduction mode (DCM) operation and the apparent switching frequency decreases. As the output current decreases, the perceived time between switching pulses increases.
