General Description
The AP1507 is a monolithic IC designed for a step-down DC/DC
converter and is capable of driving a 3A load without an external
transistor. Due to reducing the number of external components,
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 the feedback
control have good line and load regulation without an external
design. Regarding the protected function, the thermal shutdown
is to prevent over temperature operating from damaging the
device, and current limit is against over current operating of the
output switch. If the current limit function occurred and V
down to 0.5V below, the switching frequency will be reduced. The
AP1507 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 a fixed 3.3V,
5V, 12V, and an adjustable type. AP1507 is available in a 5-lead
TO-252 lead-free package.
