description (continued)
The devices feature the power-saving pulse-skip mode to extend battery life at light loads. TPS60130 and
TPS60132 include a low-battery comparator; TPS60131 and TPS60133 feature a power-good output. The logic
shut-down function reduces the supply current to 1 µA (max) and disconnects the load from the input. Special
current-control circuitry prevents excessive current from being drawn from the battery during startup. This dc/dc
converter requires no inductors and therefore EMI is of low concern. It is available in the small, thermally
enhanced 20-pin PowerPADt package (PWP).
