The TPS6206x is a family of highly efficient synchronous step down DC/DC converters. Theyprovide up to 2-A output current.
With an input voltage range of 2.9 V to 6 V, the device is a perfect fit for powerconversion from a 5-V or 3.3-V system supply rail. The TPS6206x operates at 3-MHz fixed frequencyand enters power save mode operation at light load currents to maintain high efficiency over theentire load current range. The power save mode is optimized for low output voltage ripple. For lownoise applications, TPS62065-67EVM-347 can be forced into fixed frequency PWM mode by pulling the MODE pinhigh. TPS62067 provides an open drain power good output.
In the shutdown mode, the current consumption is reduced to less than 1 μA and aninternal circuit discharges the output capacitor.
TPS6206x family is optimized for operation with a tiny 1 μH inductor and a small 10-μFoutput capacitor to achieve smallest solution size and high regulation performance.
It is available in a small 2-mm × 2-mm × 0.75-mm 8-pin WSON package.
