Description
HM1483 is a monolithic 30V, 3.0A step-down switch regulator. HM1483 integrates a 36V 65mΩ high side and a 36V, 45mΩ low side MOSFETs to provide 3.0A continuous load current over a 6.5V to 36V wide operating input voltage with 30V input over voltage protection. Peak current mode control provides fast transient responses and cycle-by-cycle current limiting. Programmable soft-start prevents inrush current at power-up. Flip-chip TSOT23-8 package makes the part best fit narrow space applications

FEATUREs
