Wide Input Voltage Range from 2.3 V to 5.5 V
synchronous step-down DC/DC converters optimized
6 MHz Regulated Frequency Operation
for battery-powered portable applications. Intended
90% Efficiency at 6 MHz Operation
for low-power applications, the TPS6262x devices
support up to 600 mA load current, and allow the use
31
μA Quiescent Current
of low cost chip inductor and capacitors.
Best in Class Load and Line Transient
With a wide input voltage range of 2.3 V to 5.5 V, the
±2% Total DC Voltage Accuracy
devices support applications powered by Li-Ion
