Description:

The TPS6214x is an easy-to-use synchronous step-down DC/DC converter optimized for high power density applications. The device features a typical switching frequency of up to 2.5MHz, allowing the use of small inductors, while DCS-Control™ topology technology provides fast transient response. With a wide operating input voltage range of 3V to 17V, the device is ideal for systems powered by lithium-ion or other battery types, as well as 12V intermediate power rails. The output voltage ranges from 0.9V to 6V, supporting continuous output currents up to 2A (with 100% duty-cycle mode). The output voltage startup ramp is controlled by the soft-start pin, allowing the device to operate as a standalone power supply or in a tracking configuration. Power sequencing is also possible via the configurable Enable (EN) and open-drain Power Good (PG) pins. In power-save mode, the device draws a quiescent current of approximately 17µA (depending on VIN). Under light-load conditions, the device automatically and seamlessly enters power-save mode, maintaining high efficiency across the entire load range. In shutdown mode, the device is turned off with a current consumption of less than 2µA. The device is available in both adjustable and fixed output voltage versions, housed in a 3mm × 3mm (RGT) 16-pin Very Thin Quad Flat No-Lead (VQFN) package.
