It provides up to 1000-mA output current from preregulated low voltage rails and consumes 15 uA (typical) in powersave mode. With an input voltage range of 2.5 V to 6 V and an output voltage accuracy of 2.5%, the device is targeted to power a large variety of automotive applications. The TPS62590-Q1 family operates at a 2.25-MHz fixed switching frequency and enters a power-save mode at light load currents to maintain a high efficiency over the entire load current range. The power-save mode is optimized for low outp...
