With an input voltage range of 2.9V to 6V the device
is a perfect fit for power conversion from a 5V or 3.3V
system supply rail. The TPS6206x operates at 3MHz
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, TPS62065 can be
forced into fixed frequency PWM mode by pulling the
MODE pin high. TPS62067 provides an open drain
power good output.
In the shutdown mode, the current consumption is
reduced to less than 1µA and an internal circuit
discharges the output capacitor.
APPLICATIONS
•
•
•
•
TPS6206x family 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.
