General Description
The AP1501 series are monolithic IC that design for
a step-down DC/DC converter, and own the ability
of driving a 3A 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 AP1501
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 packages are available in a
standard 5-lead TO-220 package and a 5-lead
TO-263.
