During no-load conditions, this internal load causes a droop rate of only 150mV per second on VOUT with COUT =lOApplying a 2Hz t0 100Hz, 2% t0 5% duty cycle signal to the SHDN pin ensures that the circuit of Figure 2 comes out of shutdown frequently enough to maintain regulation. Since the LTC1754 spends nearly the entire time in shutdown, the no-load quiescent current is approximately (VOUT) (1.5cct\)/OIVIN). N2012ZZ121T03 on stock
INVA INVB (Pins 4, 13): Inverting Input. ~ch of theINV pins is an inverting input of an op amp. Note that the INV pins are high impedance, sensitive nodes of the filter and very susceptible to coupling of unintended signals. Capacitance on the INV nodes will also affect the fre- quency response of thefilter sections. R)r these reasons, printed circuit connectionsto theINV pins must be kept as short as possible. |
