SLVSDG6B May 2016 – April 2021 TPS54302
The TPS54302 device is designed to operate in pulse-skipping mode at light-load currents to boost light-load efficiency. When the peak inductor current is lower than 500 mA (typical), the device enters pulse-skipping mode. When the device is in pulse-skipping mode, the error amplifier output voltage is clamped which prevents the high-side integrated MOSFET from switching. The peak inductor current must rise above 500 mA and exit pulse skip mode. Because the integrated current comparator catches the peak inductor current only, the average load current entering pulse-skipping mode varies with the applications and external output filters.
