TEXAS INSTRUMENTS TPS62410DRCT. 芯片, 降压转换器, 双路 2X0.8A 10SON
The is a synchronous dual step-down DC-DC Converter provides two independent output voltage rails powered by 1-cell Li-ion or 3-cell NiMH/NiCD batteries. With the EasyScale™ serial interface, the output voltages can be modified during operation. It therefore supports dynamic voltage scaling for low-power DSP and processors. The TPS62410 operates at 2.25MHz fixed switching frequency and enter the power-save mode operation at light load currents to maintain high efficiency over the entire load current range. For low-noise applications the devices can be forced into fixed frequency PWM mode by pulling the mode/data pin High. In the shutdown mode, the current consumption is reduced to 1.2µA. The device allows the use of small inductors and capacitors to achieve a small solution size.
