TPS62290DRVT

Импульсный понижающий DC-DC стабилизатор, регулируемый, 2.3В-6В (Vin), 600мВ-6В, 1А, SON-6.

The TPS62290DRVT is a highly-efficient synchronous step-down DC-to-DC Converter optimized for battery-powered portable applications. It provide up to 1000mA output current from a single Li-ion cell. With an input voltage range of 2.3 to 6V, the device support batteries with extended voltage range and are ideal to power portable applications like mobile phones. The TPS6229x device operates at 2.25MHz fixed switching frequency and enter 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 pulse width modulation (PWM) mode by pulling the MODE pin high. In the shutdown mode, the current consumption is reduced to less than 1µA. The TPS6229x device allows the use of small inductors and capacitors to achieve a small solution size.
