rp110x no.ea-239-140522 8 typical application c1 rp110 series v dd v out ce gnd c2 v out (external components) c2 0.1 f murata: grm155b31c104ka87b technical notes when using these ics, consider the following points: phase compensation in these ics, phase compensation is made for securing st able operation even if the load current is varied. for this purpose, use a capacitor c2 with good frequency ch aracteristics and esr (equivalent series resistance). (note: if additional ceramic capacitors are connected with parallel to the output pin with an output capacitor for phase compensation, the operation might be unstable. becaus e of this, test these ics with as same external components as ones to be used on the pcb.) pcb layout make v dd and gnd lines sufficient. if their impedance is hi gh, noise pickup or unstable operation may result. connect a capacitor c1 with a capacitance value as much as 0.1 f or more between v dd and gnd pin, and as close as possible to the pins. set external components, especially the output capacitor c2, as close as possible to the ics, and make wiring as short as possible.
rp110x no.ea-239-140522 9 constant slope circuits the rp110x series is equipped with a constant slope ci rcuit as a soft-start circui t, which allows the output voltage to start up gradually when the ce is turned on. the constant slope circuit minimizes the inrush curren t at the start-up and also prevents the overshoot of the output voltage. the capacitor to create the start-up slope is built in the ic that does not require any external components. the start-up time and the start-up slo pe angle are fixed inside the ic. if the capacitance of the external output capacitor (c out ) becomes more than the certain capacitance, the output current limit circuit minimizes the incoming current of the output capacitor at the start-up. as a result, the start-up time becomes longer and the start-up sl ope angle becomes more gentle. as ?inrush current characteristics example? below shows, if the c out is less than 4.7f, the constant slope circuit easily starts to function at the start-up, likewise, if the c out is over 10f, the output current limit circuit easily starts to function at the start-up. the boundary point of using these two circuits is inversely proportional to the output voltage. if the output voltage is higher, the output current limit circuit easily starts to function even if the c out capacitance is small. for more details, please refer to the graph 14 of ?inrush current characteristics example?. inrush current characteristics example (c1=none, i out =0ma, topt=25oc) rp110x25xb/d 50 150 250 350 0 100 200 300 400 ce input voltage v ce / output voltage v out (v) inrush current i vdd (ma) 4.0 3.5 3.0 2.5 2.0 1.5 1.0 0.5 0 50 150 100 250 200 350 300 0 output voltage ce input voltage inrush current v in =3.5v c out =0.1 f c out =1.0 f c out =2.2 f c out =4.7 f c out =10 f time t ( s)
