3 Description
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.
