General Description
The AP1501 is a fully integrated step-down DC/DC converter,
with the ability to drive 3A load without the need of additional
driver components. The AP1501 operates at a switching
frequency of 150KHZ enabling the use of small size filter
components. As a result, board space is reduced and BOM costs
are lowered.
The AP1501 has integrated the shutdown function that allows
standby mode to be activated via an external logic signal input.
The internal compensation facilitates feedback control for line
and load regulation without the need of an external circuitry. The
AP1501 has a built-in Thermal shutdown and Current Limit
function to prevent damage from high operating temperature and
high current operating to the output switch.
Additional features include a guaranteed +/- 4% tolerance on the
output voltage under specified input and output load conditions,
and +/- 15% on oscillator frequency. The AP1501 offers both
fixed and a Adjustable output voltages. For fixed outputs the
AP1501 supports 3.3V, 5.0V and 12V. The package options
available are standard 5-lead TO263 and TO220(R) packages.
