TPS62420DRCT Product Details

The TPS6242x 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 TPS6242x 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 TPS6242x 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 TPS6242x operates over a free-air temperature range of –40°C to 85°C. It is available in a 10-pin leadless package (3 mm × 3 mm VSON)
