The TPS6206x is a family of highly efficient synchronous step-down DC-DC converters. They
provide up to 1.6-A output current.
With an input voltage range of 2.7 V to 6 V, the device is a perfect fit for power
conversion from a single Li-Ion battery as well from 5-V or 3.3-V system supply rails. The TPS6206x
operates at 3-MHz fixed frequency and enters power save mode operation at light load currents to
maintain high efficiency over the entire load current range. The power save mode is optimized for
low output voltage ripple. For low noise applications, the device can be forced into fixed
frequency PWM mode by pulling the MODE pin high.
In the shutdown mode, the current consumption is reduced to less than 1 µA and an
internal circuit discharges the output capacitor.
TPS6206x family is optimized for operation with a tiny 1-µH inductor and a small 10-µF
output capacitor to achieve smallest solution size and high regulation performance.
The TPS6206x operates over a free air temperature of –40°C to 85°C. The device is
available in a small 2-mm × 2-mm × 0.75-mm 8-pin WSON PowerPAD
integrated circuit package.
