TPS62590-Q1 (ACTIVE) Automotive 2.5V to 6V, 2.25MHz Fixed Frequency 1A Buck Converter in 2x2mm SON Package

 

Description

The TPS62590-Q1 device is a high-efficiency synchronous step-down converter, optimized for space constrained applications and very low quiescent current requirements. It provides up to 1000-mA output current from preregulated low voltage rails and consumes 15 µA (typical) in power-save 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 output-voltage ripple. For low-noise applications, the device can be forced into fixed-frequency PWM mode by pulling the MODE pin high. In the shutdown mode, the current consumption is reduced to less than 1 µA. The TPS62590-Q1 allows the use of small inductors and capacitors to achieve a small solution size.

The TPS62590-Q1 is available in a 2-mm × 2-mm 6-pin SON package with a thermal pad for improved thermal performance.
