The TPS6280x device family is a step-down converter with 2.3-µA typical quiescent current featuring the highest efficiency and smallest solution size. TI’s DCS-Control™ topology enables the device to operate with tiny inductors and capacitors with a switching frequency up to 4 MHz. 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. 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.
