The TPS6280x device family is a
step-down converter with 2.3µA typical quiescent current featuring the highest
efficiency and smallest design 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, 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.
