The TPS62590TDRVRQ1 device is a high-efficiency synchronous buck converter optimized for very low quiescent current requirements and space-constrained applications. It delivers up to 1000mA of output current from a pre-regulated low voltage rail and consumes 15uA (type) in power-down mode.

The TPS62590TDRVRQ1 device has an input voltage range of 2.5 V to 6 V and an output voltage accuracy of 2.5% and is primarily used to power various automotive applications. To maintain high efficiency over the entire load current range, the TPS62590TDRVRQ1 device operates at a fixed switching frequency of ata225MHz and enters a power-saving mode at light load currents.

The power-saving mode of the TPS62590TDRVRQ1 device is optimized for low output voltage ripple. And for low noise, the application of the TPS62590TDRVRQ1 device can force the device into fixed frequency PWM mode by pulling the MODE pin high. In shutdown mode, the TPS62590TDRVRQ1 device’s current consumption drops below 1 uA. The TPS62590TDRVRQ1 device supports the use of small inductors and capacitors to achieve a small solution size.
