The AP1501A series are monolithic ICs that are designed for a
step-down DC/DC converter, and possess the ability to drive a
5A load without additional transistor component. 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. The AP1501A 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 includes fixed 3.3V, 5V, 12V, and an
adjustable type. The packages are available in a standard 5-lead
TO263 and TO220 packages.
