TPS54320RHLR Description
The TPS54320is a fullfeatured 17-V,3-Asynchronous step-down converter which is optimizedforsmall designs through highefficieney andintegrated high-side and low-side MOSFETs. Furtherspace savings are achieved through current modecontrol，which reduces component count. and byselecting a highswitching frequency,reducing theinductor's footprint.
The output voltage startup ramp is controlled by thesS/TR pin which allows operation as either a standalone power supply or in tracking situations. Powersequencing is also possible by correctly configuringthe enable and the open drain power good pins.
