Part Description

The TPS54320 is a full featured 17-V, 3-A synchronous step-down converter which is optimized for small designs through high efficiency and integrated high-side and low-side MOSFETs. Further space savings are achieved through current mode control, which reduces component count, and by selecting a high switching frequency, reducing the inductor's footprint. The output voltage startup ramp is controlled by the SS/TR pin which allows operation as either a stand alone power supply or in tracking situations. Power sequencing is also possible by correctly configuring the enable and the open drain power good pins. Cycle by cycle current limiting on the high-side FET protects the device in overload situations and is enhanced by a low-side sourcing current limit which prevents current runaway. Hiccup protection will be triggered if the overcurrent condition has persisted for longer than the preset time. Thermal shutdown disables the part when die temperature exceeds thermal shutdown temperature. The TPS54320 is available in a 14-pin, 3.5-mm × 3.5-mm VQFN, thermally-enhanced package.
