Description

The AME5104 is a monolithic IC that  was designed as a step-down DC/DC Converter and owns the ability of driving a
3A load without additional transistor component.The output versions of AME5104 included 3.3V,5V,12V and an adjustable type.It
operates at a switching frequency of 150KHz thus allowing smaller sized filter components otherwise it would need
lower frequency switchhing regulators.
Other features of AME5104 include a guaranteed  +4% tolerance on output voltage under specified input voltage and output load
conditions, and  +15% on the oscillator frequency. Regarding protected function, current limit is to protect over current
operating of the output switch.
