The TPS62410 device is a synchronous dual step-down DC–DC converter. It 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 V or 5 V voltage rail.

With an input voltage range of 2.5 V to 6 V, the TPS62410 is ideal for battery powered portable applications like smart phones, PDAs, and other portable equipment.

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 2.25-MHz 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 1.2 µA. The device allows the use of small inductors and capacitors to achieve a small solution size.

The TPS62410 operates over a free-air temperature range of –40°C to 85°C. It is available in a 10-pin leadless package (3 × 3 mm VSON)
