3 Description
The TPS6280x device family is a step-down converter
with 2.3μA typical quiescent current featuring the
highest efficiency and smallest design size. TI's
DCS-Control topology enables the device to operate
with tiny inductors and capacitors with a switching
frequency up to 4MHz. At light load conditions, the
device seamlessly enters power save mode to reduce
switching cycles and maintain high efficiency.
Connecting the VSEL/MODE pin to GND selects a
fixed output voltage. With only one external resistor
connected to VSEL/MODE pin, 16 internally set
output voltages can be selected. An integrated R2D
(resistor-to-digital) converter reads out the external
resistor and sets the output voltage. The same device
part number can be used for different applications
and voltage rails just by changing a single resistor.
Furthermore, the internally set output voltage provides
better accuracy compared to a traditional external
resistor divider network. After the device has started
up, the DC/DC converter enters forced PWM mode by
applying a high level at the VSEL/MODE pin. In this
operating mode, the device runs at a typical 4MHz or
1.5MHz switching frequency, enabling lowest output
voltage ripple and highest efficiency. The TPS6280x
device series comes in a tiny 6-pin WCSP package
with 0.35mm pitch.
