AVANTICS - AX3203 Series
Specification No.: 050310-FE0010
AX3203
150KHz, 5A PWM Buck DC/DC Converter
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.
Features
3.3V, 5V, 12V and adjustable
Adjustable version output voltage range: 1.3-37V
±
4% max over line and load conditions
