General Description
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
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. If current
limit function occurred and V
FB
is down to 0.5V
below, the switching frequency will be reduced.
The AP1509 series operates at a switching
frequency of 150KHz thus allowing smaller sized
filter components than what would be needed with
lower
frequency
switching
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 8-lead SOP-8 package.
