General Description
The AP1506 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 to prevent 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 AP1506
series operate 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, a 5-lead TO-263 or 8-lead
PDIP.
