DESCRIPTIOn
The LTM@4649is a complete 10A highefficiency switching mode step-down DC/DC uModule? regulator in a 9mmx15mm×4.92 BGA package. Included in the package are the switching controller, power FETs, inductor, and all support components. Operating over an input voltage range of4.5V to 16V, the LTM4649IY#PBF supports an output voltage range of 0.6V to 3.3V, set by a single external resistor. This high efficiency design delivers 10A continuous current. Only bulk input and output capacitors are needed.
High switching frequency and a current mode architecture enable a very fast transient response to line and load changes without sacrificing stability. The device supports frequency synchronization, programmable multiphase operation, and output voltage tracking for supply rail sequencing.
Fault protection features include output overvoltage andovercurrent protection. The LTM4649IY#PBF is offered in a small 9mm×15mm×4.92mm BGA package available with SnPb or RoHS compliant terminal finish.
