General Description
The AP1501A series are monolithic IC that design
for a step-down DC/DC converter, and own the
ability of driving a 5A load without additional
transistor component. Due to reducing the number
of external component, the board space can be
saved easily. The external shutdown function can
be controlled by logic level and then come into
standby mode. The internal compensation makes
feedback control have good line and load regulation
without external design. 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. The AP1501A series 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. The output version included fixed 3.3V,
5V, 12V, and an adjustable type. The packages are
available in a standard 5-lead TO-220 package and
a 5-lead TO-263.
