The TPS6280x device family is a step down converter with 2.3-µA typical quiescent current
featuring highest efficiency and smallest solution size. TIs DCS-Control™ topology enables the
device to operate with tiny inductors and capacitors with a switching frequency up to 4MHz. At
light load conditions, it seamlessly enters Power Save Mode to reduce switching cycles and
maintaining 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. Once 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 4-MHz or 1.5-MHz switching frequency, enabling
lowest output voltage ripple and highest efficiency. The TPS6280x device series comes in a tiny
6-pin WCSP package with 0.35-mm pitch.
