AX3203
150KHz, 5A PWM Buck DC/DC Converter
Page No. : 1/7
AX3203 Series
Description
The AX3203 is Monolithic IC that design for a step-down DC/DC Converter, and own
the ability of driving a 5A load without additional transistor component. The output
version included 3.3V, 5V, 12V and an adjustable type. It operates at a switching
frequency of 150KHz thus allowing smaller sized filter components than what would
be needed with lower frequency switching regulators. Other features 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, thermal shutdown is to prevent over temperature operating from damage,
and current limit is against over current operating of the output switch.
