Function Description
PWM Control
The AP1510 is a DC/DC converter that employs pulse width
modulation (PWM) scheme. Its pulse width varies in the range of
0% to 99%, based on the output current loading. The output
ripple voltage caused by the PWM high frequency switching can
easily be reduced through an output filter. Therefore, this
converter provides a low ripple output supply over a broad range
of input voltage & output current loading
Under Voltage Lockout
The under voltage lockout circuit of the AP1510 assures that the
high-side MOSFET driver remains in the off state whenever the
supply voltage drops below 3.3V. Normal operation resumes
once VCC rises above 3.5V.
Current Limit Protection
The current limit threshold is set by external resistor ROCSET
connected from VCC supply to OCSET pin. The internal sink
current IOCSET (90uA typical) across this resistor sets the voltage
at OCSET pin. When the PWM voltage is less than the voltage at
OCSET, an over-current condition is triggered.
The current limit threshold is given by the following equation:

IPEAK is the output peak current; RDS (ON) is the MOSFET ON
resistance. FS is the PWM frequency (300KHz typical). Also, the
inductor value will affect the ripple current
ΔI.
The above equation is recommended for input voltage range of
5V to 18V. For input voltage lower than 5V, higher than 18V or
ambient temperature over 100°C, high ROCSET is recommended.
The maximum ROCSET value should not exceed AP1510 maximum
current output.
