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
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.
