EML3230

ESMT/EMP Preliminary EML3230 3A, 23V, 340KHz Synchronous Step-Down Converter General Description The EML3230 is a synchronous step-down DC/DC converter that provides wide 4.5V to 23V input voltage range and 3A continuous load current capability. „ „ „ „ „ „ Adjustable Output Voltage from 0.925V to 20V 100mΩ integrated Power MOSFET High Efficiency Up to 93% Fixed 340KHz Switching Frequency Current Mode Operation Adjustable Soft-Start Cycle-by-Cycle current limit Input Under Voltage Lockout Over-Temperature Protection 10uA Shutdown Current Thermal Enhanced SOP-8 Package RoHS Compliant Fault protection includes cycle-by-cycle current limit, input UVLO, output over voltage protection and thermal shutdown. Besides, adjustable soft-start function prevents inrush current at turn-on. This device uses current mode control scheme that provides fast transient response. In shutdown mode, the supply current is about 10uA. „ „ „ „ „ „ The EML3230 is available in an 8-pin SOP package, provides a very compact system solution and good thermal conductance.
