Step-up PWM DC/DC Converter
APE1901
GENERAL DESCRIPTION
The APE1901 is high efficient step-up DC/DC converter. Large output current is
possible having a built in internal N channel MOSFET, and using an external coil and
diode.
The APE1901 can be operated at switching frequencies of 500kHz allowing for easy
filtering and low noise, the size of the external components can be reduced.
Output voltage is programmable with 1.0V of standard voltage supply internal, and
using externally connected components, output voltage (FB) can be set up at will.
This converter also contains an error amplifier circuit as well as a soft-start circuit
that prevents inrush-current at startup. An enable function and thermal shutdown
functions are built inside.
FEATURES
- Input voltage: 3V to 15V
- Output voltage: 3.3V to 28V(±2.5%）
- Duty ratio: 0% to 80% PWM control
- Switch current: 3A(MAX)
- Oscillation frequency: 500KHz.
- Enable function
- Soft-start function
- Thermal Shutdown function
- Built-in internal SW N-channel MOS
- SOP-8L Pb-Free Package.

Function Descriptions
PWM Control
The APE1901 consists of DC/DC converters that employ a pulse-width modulation
(PWM) system.
In converters of the APE1901, the pulse width varies in a range from 0 to 80%,
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.
