Texas Instruments TPS62242QDDCRQ1

The TPS62242-Q1 device is a highly efficient buck converter optimized for battery-powered portable applications. The device provides up to 300-mA output current from a single Li-Ion cell and is ideal for battery-powered portable applications, automotive applications, and other equipment like Advanced Driver Assistance Systems (ADAS).

With an input voltage range of 2 V to 6 V, the device supports applications powered by Li-Ion batteries with extended voltage range, two- and three-cell alkaline.

The TPS62242-Q1 operates at 2.25-MHz fixed-switching frequency and enters the power-save mode of operation at light load currents to maintain high efficiency over the entire load current range.

The power-save mode is optimized for low output-voltage ripple. In shutdown mode, the current consumption is reduced to less than 1 µA. With 2.25-MHz fixed frequency and a 1.2-V fixed output voltage, the TPS62242-Q1 device allows the use of small inductors and capacitors to achieve a small solution size.

The TPS62242-Q1 operates over a free-air temperature range of –40°C to 115°C. The device is available in a 5-pin SOT 2.90-mm × 1.60-mm package.
