TPS62290-Q1 - 采用 2x2mm SON 封装的汽车类 2.25MHz 1A 降压转换器 - 转换器（集成开关） - DC/DC开关稳压器 - TI公司（Texas Instruments，德州仪器）
The TPS6229x-Q1 is a highly efficient synchronous step down dc-dc converters optimized for battery-powered portable applications. TPS6229x-Q1 provides up to 1000-mA output current from a single Li-Ion cell.
With an input voltage range of 2.3 V to 6 V, the device supports batteries with extended voltage range and are ideal to power portable applications like mobile phones and other portable equipment.
The TPS6229x-Q1 operates at 2.25-MHz fixed switching frequency and enters Power Save Mode 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. 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 1μA. The TPS6229x-Q1 allows the use of small inductors and capacitors to achieve a small solution size.
The TPS6229x-Q1 is available in a 2-mm × 2-mm 6-pin SON package.
