LTM4622IY#PBF

LTM4622IY#PBF is an Analog Devices dual 2.5 A or single 5 A (two-phase parallelable) step-down uModule regulator in a 6.25 x 6.25 x 1.82 mm LGA package - for dense point-of-load rails on FPGA, ASIC and embedded boards, including PCIe and AdvancedMC cards with strict height limits. The 1.82 mm ultrathin profile is the selection point: the regulator mounts on the backside of the PCB, freeing topside area for digital ICs where conventional regulators do not fit, while the 3.6 V to 20 V input and 0.6 V to 5.5 V output range covers both 12 V intermediate-bus and 3.3 V direct conversions. Two channels parallel for a single 5 A rail with current sharing, and output-voltage tracking plus soft-start simplifies multi-rail sequencing; ADI holds the part active with a current Rev J datasheet. Selection advice: the IY#PBF code is the industrial-grade ultrathin LGA (1.82 mm) - the thinner option versus the BGA package variant, so verify backside height budget and keep-out before layout; LGA assembly needs the same care as BGA (solder paste profile, thermal vias). Against the quad 4 A LTM4644IY#PBF on this site - the LTM4622 suits boards that need two rails or one 5 A rail in minimal height; for a single output beyond 5 A, step up to a higher-current uModule family rather than pushing paralleled phases past their rating.
