The device is housed in a small surface mount 15mm × 15mm × 2.82mm LGA package. Operating over an input voltage range of 4.5V to 20V, the LTM4603 supports an output voltage range of 0.6V to 5V as well as output voltage tracking and margining. The high efficiency design delivers 6A continuous current (8A peak). Only bulk input and output capacitors are needed to complete the design. The low pr...
