Overview
ESMT/EMP Preliminary EML3220 2A, 23V, 340KHz Synchronous Step-Down Converter General Description The EML3220 is a synchronous step-down DC/DC converter that provides wide 4.
5V to 23V input voltage range and 2A continuous load current capability.
„ „ „ „ „ „ 2A Output Current Adjustable Output Voltage from 0.
925V to 20V 130mΩ 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 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 EML3220 is available in an 8-pin SOP package, provides a very compact system solution and good thermal conductance.
Applications „ „ „ „ „ Set-Top-Box DVD, LCD Displays OLPC, Netbook Distributed Power System Datacom, XDSL Features „ Wide Input Voltage from 4.
