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
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.
