DATA SHEET AAT2113B 3.3MHz, Fast Transient 1.5A Step-Down Converter in an 2mm x 2mm Package General Description The AAT2113B SwitchReg™ is a 1.5A step-down converter with a typical input voltage of 3.3V and a fixed output voltage of 1.2V or an adjustable output. The 3.3MHz switching frequency enables the use of small external components. The ultra-small 2mm x 2mm footprint and high efficiency make the AAT2113B an ideal choice for portable applications. The AAT2113B delivers 1.5A maximum output current while consuming only 55μA no-load quiescent current. Low RDS(ON) integrated MOSFETs and 100% duty cycle operation make the AAT2113B the ideal choice for high output voltage, high current applications which require a low dropout threshold.
