Texas Instruments TPS62801YKAR

The TPS6280x device family is a step down converter with 2.3-µA typical quiescent current featuring highest efficiency and smallest solution size. TI’s DCS-Control™ topology enables the device to operate with tiny inductors and capacitors up to a 4 MHz switching frequency. 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 1.2-V 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 typically 4-MHz switch frequency enabling lowest output voltage ripple. The TPS6280x device series comes in a tiny 6-pin WCSP package with 0.35-mm pitch.
