Product Overview

The TPS62202DBVT is a synchronous Step-down Converter ideally suited for portable systems powered by 1-cell Li-ion or 3-cell NiMH/NiCd batteries. It is suitable to operate from a standard 3.3 or 5V voltage rail. With an output voltage range of 6 down to 0.7V and up to 300mA output current. Under nominal load current, the devices operate with a fixed switching frequency of typically 1MHz. At light load currents, the part enters the power save mode operation, the switching frequency is reduced and the quiescent current is typically only 15µA, therefore, it achieves the highest efficiency over the entire load current range. The TPS6220x needs only three small external components. An advanced fast response voltage mode control scheme achieves superior line and load regulation with small ceramic input and output capacitors.
  • High-efficiency synchronous step-down
  • Converter with up to 95% efficiency
  • Highest efficiency over wide load current range due to power save mode
  • Soft-start
  • Dynamic output-voltage positioning
  • 15µA Typical quiescent current
  • 100% Duty cycle low-dropout operation
  • Green product and no Sb/Br

Applications

Computers & Computer Peripherals, Communications & Networking, Portable Devices, Power Management, Audio, Imaging, Video & Vision
