The AP1509 series are monolithic IC designed for a step-down
DC/DC converter, and own the ability of driving a 2A load without
additional transistor. It saves board space. The external
shutdown function can be controlled by logic level and then come
into standby mode. The internal compensation makes feedback
control having 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 occurs and V
FB
is down below 0.5V, the
switching frequency will be reduced. The AP1509 series operates
at a switching frequency of 150KHz thus allow 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 chips are available in a standard 8-lead
SOP-8 package.
