LTM4601/LTM4601-1 12A µModule Regulators with PLL, Output Tracking
and Margining Description
The LTM®4601 is a complete 12A step-down switch mode DC/DC power supply with onboard switching controller,
MOSFETs, inductor and all support components. The µModule® regulator is housed in small surface mount 15mm × 15mm × 2.82mm LGA and 15mm × 15mm × 3.42mm BGA packages. Operating over an input
voltage range of 4.5V to 20V, the LTM4601 supports an output
voltage range of 0.6V to 5V as well as output
voltage tracking and margining. The high efficiency design delivers 12A continuous current (14A peak). Only bulk input and output
capacitors are need...
