DESCRIPTION
The LTM® 4603HV is a complete 6A step-down switch mode DC/DC power supply with onboard switching controller, MOSFETs, inductor and all support components. The μModule^TM is housed in a small surface mount 15mm × 15mm ×2.8mm LGA package. Operating over an input voltage range of 4.5 to 28V, the LTM4603HV 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.
