The AP1512/A is a monolithic IC that design for a
step-down DC/DC converter, and own the ability of
driving a 2A (3A for AP1512A) 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
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 AP1512/A operates at a
switching frequency of 50KHz 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.
