The TPS6218x is a synchronous dual-phase step-down DC-DC converter for low profile powerrails. It operates with two identical, current balanced phases that are peak current controlledenabling use in height limited applications.
With a wide operating input voltage range of 4 V to 15 V, the device is ideally suitedfor systems powered from multi-cell Li-Ion batteries or 12-V rails. The output current of 6 A iscontinuously provided by two phases of 3 A each, allowing the use of low profile externalcomponents. The phases operate out of phase, reducing switching noise significantly.
The TPS6218x automatically enters Power Save Mode to maintain high efficiency down tovery light loads. It also incorporates an AutomaticEfficiency Enhancement(AEE™) for theentire duty cycle range.
The device features a Power Good signal, as well as an adjustable soft start. Thequiescent current is typically 28 µA, it is able to run in 100% mode, and it has no duty cyclelimitation even at lowest output voltage.
The TPS6218x, available in adjustable and fixed output voltage options, is packaged in asmall 24-bump, 0.5 mm pitch DSBGA package.
