3 Description
The TPS6206x is a family of highly efficient
synchronous step down DC/DC converters. They
provide 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 power conversion from a 5-V or 3.3-
V system supply rail. 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, TPS62065 can be
forced into fixed frequency PWM mode by pulling the
MODE pin high. TPS62067 provides an open drain
power good output.
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.
It is available in a small 2-mm × 2-mm × 0.75-mm 8-
pin WSON package.
