r1190x 9 technical notes when using these ics, consider the following points: phase compensation in these ics, phase compensation is made for securing stable operation even if the load current is varied. for this purpose, use a capacitor c out with good frequency characteristics 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 high, noise pickup or unstable operation may result. connect a capacitor with a capacitance value as much as 4.7 f or more between v dd and gnd pin, and as close as possible to the pins. set external components, especially the output capacitor, as close as possible to the ics, and make wiring as short as possible. (refer to the typical application diagram below) thermal shutdown function there is the built-in thermal-shutdown function in r1 190 series. it discontinues operation of the ic when the junction temperature becomes over 150c (typ.) and ic re-operates when the junction temperature under 130c . if the temperature increasing keeps the ic repeats on and off operating. the output becomes the pulse condition. chip enable (ce) circuit for the output voltage stability, please do not use the intermediate electric potential (the voltage value between v ceh and v cel ) that causes the supply current increa sing and the unstable of output voltage. inrush-current limit function r1190 series has the function to limit the inrush-cur rent, it limited approximately 0.4a when the voltage regulator is turn on. it is also possible to set time of the rush-current limitation by connecting capacitor with delay pin. the rush-current time (t d ) and the value of capacitor (c d [f]) is calculatable by the following formula; t d =(0.000198 + (3.79e+7 x c d )) x v in the inrush-current is limited even if the capacitor is not connected with the delay pin. in this case, the time is calculated as c d =0 by the formula above. though, if the value of time is insufficient for controlling the inrush-current, please connect the capacitor with delay pin. the delay pin is used as open when the capa citor is not used. please use the delay pin as open when the capacitor is not used. auto-discharge function r1190xxxxd series has the auto-discharge function. when "l" signal is put into the chip-enable pin (ce), the switch between v out and gnd is turned on and the charge at capacitor is discharged rapidly by the auto-discharge function. * delay pin is open when c d pin is not used. v dd ce gnd v out v out c in c out typical application (external components) c in : 4.7 f c out : 4.7 f r1190x series v in delay c d
