ADAS Applications
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 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. In the shutdown mode, the
current consumption is reduced to 5 µA and an
internal circuit discharges the output capacitor. The
TPS62065-Q1 and TPS62067-Q1 device 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 TPS62065-Q1 and TPS62067-Q1 device is
available in a small 2 × 2 × 0,75-mm 8-pin WSON
package.
