STOD03B is capable of supplying a load current from 150 ma to 200 ma. inductors with a saturation current as a minimu m of 1 a must be selected. 1 l fs v 2 ) vin v ( vin vin 1 i v i mid min mid min min out mid boost peak ? + = ? 2 l fs ) vin 2 vo ( 2 2 vo vin vin 2 xi ) 2 vo vin ( i min min min min min out min min inverting peak ? + ? = ?

order to filter any disturbance present in the in put line and to obtain stable operation for the two switching converters. a minimum real capacitance value of 6 f must be guaranteed for c mid , c o1 and c o2 in all conditions. consider ing tolerance, temperature variation and dc polarization, 2 x 10 f, 10 v 10% as c mid , a 10 f 10v 10% capacitor as c o1 and 2 x 10 f 10 v 10% as co2 can be used to achieve the needed 6 f. 7.2 recommended pcb layout the STOD03B is a high frequency power switch ing device and therefore requires a proper pcb layout in order to obtain the necessary stab ility and optimize line/load regulation and output voltage ripple. analog input (v ina ) and power input (v inp ) must be kept separated and connected together at the c in pad only. the input capacitor must be as close as possible to the ic. in order to minimize ground noise, a common ground node for power ground and a different one for analog ground must be used. in the recommended layout, the agnd node is placed close to c ref ground while the pgnd node is centered at c in ground. they are connected by a separated layer routing on the bottom through vias. the exposed pad is connected to agnd through vias. figure 10. top layer and top silk-screen (top view, not to scale) application information STOD03B 14/22 doc id 022613 rev 1 figure 11. bottom layer and silk-screen (top view, not to scale) STOD03B detailed description doc id 022613 rev 1 15/22 8 detailed description 8.1 general description the STOD03B is a high efficiency dual dc-dc converter which integrates a step-up with an ldo and inverting power stages suitable for supplying amoled panels. thanks to the high level of integration it needs only 6 external components to operate and it achieves very high efficiency using a synchronous rectification te chnique for each of the two dc-dc converters. this topology of a boost followed by an ldo re gulator offers an efficient ripple reduction solution for loads up to 200 ma. the controller uses an average current mode technique in order to obtain good stability and precise voltage regulation in a ll possible conditions of input voltage, output voltage, and output current. in addition, the peak inductor current is monitored in order to avoid saturation of the coils. the STOD03B implements a power saving technique in order to ma intain high efficiency at very light load and it switches to pwm operation as the load increases, in order to guarantee the best dynamic performance and low noise operation. the STOD03B avoids battery leakage thanks to the true-shutdown feature and it is self protected by overtemperature. undervoltage lockout and soft-start guarantee proper operation during startup. 8.1.1 multiple operation modes both the step-up and the inverting stage of the STOD03B operate in three different modes: pulse skipping mode (psm), discontinuous conduction mode (dcm), and continuous conduction mode (ccm). it switches automat ically between the three modes according to input voltage, output current, and output voltage conditions. pulse skipping operation: the STOD03B works in pulse skipping mode when the load current is below a few ma. the load current level at which this way of operating occurs depends on input voltage only for the step-up converter and on input voltage and negative output voltage (v o2 ) for the inverting converter. discontinuous conduction mode: when the load increases above some tens of ma, the STOD03B enters dcm operation. in order to obtain this type of operation the controller must avoid the inductor current going negative. the discontinuous mode detector (dmd) blocks sense the voltage across the synchronous rectifiers (p1b for the step-up an d n2 for the inverting) and turn off the switches when the voltage crosses a defined th reshold which, in turn , represents a certain current in the inductor. this cu rrent can vary according to the slope of the inductor current which depends on input voltage, inductance value, and output voltage. continuous conduction mode: at medium/high output loads, the STOD03B enters full ccm at constant switching frequency mode for each of the two dc-dc converters. detailed description STOD03B 16/22 doc id 022613 rev 1 8.1.2 enable pin the device operates when the en pin is set hi gh. if the en pin is set low, the device stops switching, and all the internal blocks are turned off. in this condition the current drawn from v inp /v ina is below 1 a in the whole temperature ra nge. in addition, the internal switches are in an off state so the load is electrically disconnected from the input, this avoids unwanted current leakage from the input to the load. 8.1.3 soft-start and in rush current limiting after the en pin is pulled high, or a fter a suitable volt age is applied to v inp , v ina and en, the device initiates the startup phase. as a first step, the c mid capacitor is charged and the p1b switch implements a current limiting technique in order to keep the charge current below 400 ma. this avoids the battery overloading during startup. after v mid reaches the v inp voltage level, the p1b switch is fully turned on and the soft-start procedure for the step-up is started. after around 2 ms the soft-start for the inverting is started. the positive and negative voltages are under regulation by around 6 ms after the en pin is asserted high. 8.1.4 undervoltage lockout the undervoltage lockout function avoids im proper operation of the STOD03B when the input voltage is not high enough. when the input voltage is below the uvlo threshold the device is in shutdown mode. the hysteresis of 50 mv avoids unstable operation when the input voltage is close to the uvlo threshold. 8.1.5 overtemperature protection an internal temperature sensor continuously monitors the ic junction temperature. if the ic temperature exceeds 140 c, typical, the de vice stops operating. as soon as the temperature falls below 125 c, typical, normal operation is restored.
