Dual 3A buck in a 3x5 mm VQFN
The TPS62442RQRR is a dual-channel synchronous step-down regulator delivering 3 A on each output from a 2.75 V to 6 V input rail.
Output voltage and thermal envelope
Output is adjustable from 0.6 V up to 5.5 V.
That pad needs a solid via array to the ground plane to keep junction temperature under 150°C at full load. The part is surface-mount — rework with a hot-air station is possible if the pad is properly tinned, but the small pitch means a stencil is the reliable production path.
