AP1513
PWM Control 2A Step-Down Converter
Function Description
PWM Control
The AP1513 consists of DC/DC converters that
employ a pulse-width modulation (PWM) system.
In converters of the AP1513, the pulse width varies
in a range from 0 to 100%, according to the load
current. The ripple voltage produced by the
switching can easily be removed through a filter
because the switching frequency remains constant.
Therefore, these converters provide a low-ripple
power over broad ranges of input voltage and load
current.
Under Voltage Lockout
The under voltage lockout circuit of the AP1513
assures that the high-side MOSFET driver outputs
remain in the off state whenever the supply voltage
drops below 3.3V. Normal operation resumes once
V
CC
rises above 3.5V.

Current Limiting
The current limit threshold is setting by the external
resistor connecting from V
CC
supply to OCSET. The
internal 100uA sink current crossing the resistor
sets the voltage at the pin of OCSET. When the
PWM voltage is less than the voltage at OCSET, an
over-current condition is triggered.
