AP1515
150KHz, 1.5A PWM Buck DC/DC Converter
Function Description
Pin Functions
+V
IN
This is the positive input supply for the IC switching
regulator. A suitable input bypass capacitor must be
present at this pin to minimize voltage transients
and to supply the switching currents needed by the
regulator.
Ground
Circuit ground.
Output
Internal switch. The voltage at this pin switches
between (+V
IN
– V
SAT
) and approximately – 0.5V,
with a duty cycle of approximately V
OUT
/ V
IN
. To
minimize coupling to sensitive circuitry, the PC
board copper area connected to this pin should be
kept a minimum.

Feedback
Senses the regulated output voltage to complete
the feedback loop.
SD
Allows the switching regulator circuit to be
shutdown using logic level signals thus dropping
the total input supply current to approximately
150uA. Pulling this pin below a threshold voltage of
approximately 1.3V turns the regulator on, and
pulling this pin above 1.3V (up to a maximum of
18V) shuts the regulator down. If this shutdown
feature is not needed, the SD pin can be wired to
the ground pin.
