600mA 超低 IQ 降压转换器

 

描述

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 with a switching frequency up to 4MHz. At light load conditions, it 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.
