The TPS62400DRCTG4 is a synchronous dual step-down DC-to-DC Converter optimized for battery-powered portable applications. The device provides two independent output voltage rails powered by 1-cell Li-ion or 3-cell NiMH/NiCD batteries. The device is also suitable to operate from a standard 3.3 or 5V voltage rail. With an input voltage range from 2.5 to 6V. With the EasyScale serial interface the output voltages can be modified during operation. The TPS6240x operates at a 2.25MHz fixed switching frequency and enters 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, typical. The devices allow the use of small inductors and capacitors to achieve a small solution size.
