3 Description
The TPS62065-Q1, TPS62067-Q1, and TPS62067AQ1
devices are highly-efficient, synchronous, stepdown
DC/DC converters. The device provides up to
2-A output current.
With an input voltage range of 2.9 V to 6 V the
device is an excellent fit for power conversion from
a 5-V or 3.3-V system supply rail. The TPS62065-Q1
and TPS62067-Q1 device 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 TPS62065-Q1 device can be
forced into fixed frequency PWM mode by pulling
the MODE pin high. The TPS62067-Q1 provides an
open drain power good output and has a power
save mode, while the TPS62067A-Q1 operates in
fixed frequency PWM mode. In the shutdown mode,
the current consumption is reduced to 5 μA and
an internal circuit discharges the output capacitor.
The TPS62065-Q1, TPS62067-Q1, and TPS62067AQ1
devices are optimized for operation with a tiny
1-μH inductor and a small 10-μF output capacitor
to achieve smallest design size and high regulation
performance.
The new product, TPS628502-Q1, offers reduced
BOM cost and size, higher efficiency and other
features.
