650 mA, 6 MHz — what this regulator delivers for your rail
The Texas Instruments TPS626751YFDR is a step-down (buck) DC-DC converter that delivers a fixed 1.2 V output from a 2.3 V to 4.8 V input rail, rated for 650 mA continuous output. Synchronous rectification is included, which helps maintain efficiency across the load range.
Package and PCB — the DSBGA footprint demands a clean layout
The 6-XFBGA (DSBGA) package has a 0.4 mm ball pitch — the same as many mobile PMICs — so the PCB layout must use micro-vias or via-in-pad to fan out the centre balls. A 2-layer board is possible if the ground plane sits on layer 2 and the input/output caps are placed within 2 mm of the respective balls.
