8/20 xcm406 series v out 0.8v ~ 1.45v 1.5v ~ 1.75v 1.8v ~ 5.0v c l R 6.8 f R 4.7 f R 1.0 f operational explanation the voltage, divided by resistors r1 & r2, which are connected to the v rout pin is compared with the internal reference voltage by the error amplifier. the p-channel mosfet connected to the v rout pin is then driven by the subsequent output signal. the out put voltage at the v out pin is controlled and stabilized by negative feedback. the constant current limit circuit and short circuit protection operate in relation to the level of output current. with the xcm406 series regulator, a stable output voltage is achievable even if low esr capacitors are used, as a phase compensation circuit is built into the regulator. in or der to ensure the effectiveness of the phase compensation, we suggest that an output capacitor (c l ) will be connected as close as possible between the output pin (v rout ) and the v ss pin. please use an output capacitor (c l ) with a capacitance based on the chart below. we also suggest an input capacitor (c in ) of 1 f. this should be connected between v in and v ss in order to stabilize input power source. output capacitor corresponding table the xcm406 series regulator offers a combination of current lim it and short circuit protection by means of a built-in fixed current limiter circuit and a foldback circuit. when drops fu rther and output current decreases. when the output pin is shorted, a current of abo ut 50ma flows. the load current r eaches the current limit level, t he fixed current limiter circuit operates and output voltage drops. as a result of this drop in output voltage, the foldback circuit operates, the output voltage the ic's internal regulator circuitry can be shut down vi a the signal from the en pin with the xc6210 series. in shutdown mode, output at the v rout pin will be pulled down to the v ss level via r1 & r2. options are available for the en pin logic (see the product classification). note that as the xcm406aa types are 'high active / no pull-down', operations will become unstable with the en pin open. alt hough the en pin is equal to an inverter input with cmos hysteresis, with either the pull-up or pull-down options, the ce pin input current will increase when the ic is in operation. we suggest that you use this ic with either a v in voltage or a v ss voltage input at the en pin. if this ic is used with the correct specifications for the en pin, t he ic will operate normally. however, s upply current may increase as a result of through current in the ic's internal circuitry if a voltage other than v in or v ss is applied. notes on use 1. please use this ic within the stated maximum ratings. fo r temporary, transitional voltage drop or voltage rising phenomenon, the ic is liable to malfunction should the ratings be exceeded. 2. where wiring impedance is high, operations may become unstable due to noise and/or phase lag depending on output current. please strengthen v in and v ss wiring in particular. 3. please wire the input capacitor (c in ) and the output capacitor (c l ) as close to the ic as possible. when rapid input fluctuation or load fluctuation occurs, pleas e increase the capacitor value such as c in or cl to stabilize the operation. 4. the two dies in the same package are closely pl aced so that one heat gener ation affects the other. heat dissipation should be evaluated on the actual board design before finalizing. in case of light load operation like 100 a below, but the other side is heavy lo ad operation, the light load output vo ltage may happen to be elevated up to the input voltage level as a result of leakage current. as a counter measure when it happened, adding one resistor between v out and v ss pins is recommended. 5. torex places an importance on improv ing our products and its reliability. however, by any possibility, we would request user fail-sa fe design and post-aging treatm ent on system or equipment.
