The TPS6242x device is a synchronous dual step-down DCDC 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)
