ADM8660 voltage inverter configuration oscillator frequency the internal charge-pump frequency may be selected to be either 25 khz or 120 khz using the frequency control (fc) input. with fc unconnected (adm660) or connected to gnd (ADM8660), the internal charge pump runs at 25 khz while, if fc is connected to v+, the frequency is increased by a factor of five. increasing the frequency allows smaller capacitors to be used for equivalent performance or, if the capacitor size is un- changed, it results in lower output impedance and ripple. if a charge-pump frequency other than the two fixed values is desired, this is made possible by the osc input, which can either have a capacitor connected to it or be overdriven by an external clock. refer to the typical performance characteris- tics, which shows the variation in charge-pump frequency versus capacitor size. the charge-pump frequency is one-half the oscil- lator frequency applied to the osc pin. if an external clock is used to overdrive the oscillator, its levels should swing to within 100 mv of v+ and gnd. a cmos driver is, therefore, suitable. when osc is overdriven, fc has no effect but lv must be grounded. note that overdriving is permitted only in the voltage inverter configuration. table i. adm660 charge-pump frequency selection fc osc charge pump c1, c2 open open 25 khz 10 f v+ open 120 khz 2.2 f open or v+ ext cap see typical characteristics open ext clk ext clk frequency/2
rev. b adm660/ADM8660 e9e current levels. the adm660/ADM8660 is tested using low esr, 10 f, capacitors for both c1 and c2. smaller values of c1 increase the output resistance, while increasing c1 will reduce the output resistance. the output resistance is also depen- dent on the internal switches on resistance as well as the capacitors esr, so the effect of increasing c1 becomes negligible past a certain point. figure 9 shows how the output resistance varies with oscillator frequency for three different capacitor values. at low oscillator frequencies, the output impedance is dominated by the 1/f c term. this explains why the output impedance is higher for smaller capacitance values. at high oscillator frequencies, the 1/f c term becomes insignificant and the output impedance is dominated by the internal switches on resistance. from an out- put impedance viewpoint, therefore, there is no benefit to be gained from using excessively large capacitors. oscillator frequency e khz 500 400 0 0.1 100 110 300 200 100 c1 = c2 = 2.2 f c1 = c2 = 1 f c1 = c2 = 10 f output resistance e figure 9. output impedance vs. oscillator frequency capacitor c2 the output capacitor size c2 affects the output ripple. increas- ing the capacitor size reduces the peak-to-peak ripple. the esr affects both the output impedance and the output ripple. reducing the esr reduces the output impedance and ripple. for convenience it is recommended that both c1 and c2 be the same value. table iii. capacitor selection charge-pump capacitor frequency c1, c2 25 khz 10 f 120 khz 2.2 f power efficiency and oscillator frequency trade-off while higher switching frequencies allow smaller capacitors to be used for equivalent performance, or improved performance with the same capacitors, there is a trade-off to consider. as the oscillator frequency is increased, the quiescent current increases. this happens as a result of a finite charge being lost at each switching cycle. the charge loss per unit cycle at very high frequencies can be significant, thereby reducing the power effi- ciency. since the power efficiency is also degraded at low oscillator frequencies due to an increase in output impedance, this means that there is an optimum frequency band for maximum power transfer. refer to the typical performance characteristics section. bypass capacitor the ac impedance of the adm660/ADM8660 may be reduced by using a bypass capacitor on the input supply. this capacitor should be connected between the input supply and gnd. it will provide instantaneous current surges as required. suitable capacitors of 0.1 f or greater may be used.
