DESCRIPTION
The TPS62060 is a highly efficient synchronous
step-down DC-DC converter and provides up to 1.6A
output current.
With an input voltage range of 2.7V to 6V the device
is a perfect fit for power conversion from a single
Li-Ion battery as well from 5V or 3.3V system supply
rails. The TPS62060 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 1µA and an internal circuit
discharges the output capacitor.
TPS62060 is optimized for operation with a tiny
1.0µH inductor and a small 10µF output capacitor to
achieve smallest solution size and high regulation
performance.
The TPS62060 is available in a small 2x2x0.75mm
8-pin SON package.
