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.
