Overview
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.
The AAT2113B provides excellent transient response and output accuracy across the operating range.
No external compensation is required.
The AAT2113B maintains high efficiency throughout the load range.
The unique low-noise architecture reduces ripple and spectral noise.
The AAT2113B automatically optimizes efficiency during Light Load mode (LL) and maintains constant frequency and low output ripple during PWM mode.
Over-temperature and short circuit protection safeguard the AAT2113B and system components from damage.
The AAT2113B is available in a Pb-free, ultra-small, low profile, 8-pin 2mm x 2mm FTDFN package.
The product is rated over a temperature range of -40°C to 85°C.
