Dual, Adjustable, 600mA And 1000mA, 2.25MHz Step-Down Converter With 1-Wire Interface In QFN

The TPS62420 device is a synchronous dual Step-down DC-DC Converter optimized for battery powered portable applications. 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 3.3V or 5V voltage rail.
With an input voltage range of 2.5V to 6V, the TPS62420 is ideal to power 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 TPS62420 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 1.2A. The device allows the use of small inductors and capacitors to achieve a small solution size.
The TPS62420 is available in a 10-pin leadless package (33mm QFN)
