General Description
The AP1507 series are monolithic IC designed for a
step-down DC/DC converter, and own the ability of
driving a 3A load without external transistor. 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. If current limit function occurred
and V
FB
is 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 fixed 3.3V, 5V, 12V, and an adjustable
type. The package is available in a 5-lead TO-252.
