... PWM Control The APE3061 is high efficient PWM step-up controller. In controllers of the APE3061, the pulse width varies in a range from 0 to 85%, 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, APE3061 provide a low-ripple power over broad ranges of input voltage and load current ...

... Add a 4.7uF output bypass capacitor in order to reduce output ripple effectively. Layout Guidance When laying out the PC board, the following suggestions should be taken to ensure proper operation of the APE3061. These items are also illustrated graphically in below. 1. The power traces, including the NMOS Drain & Source trace, the inductor and the C1 trace should be kept short, direct and wide to allow large current flow ...
