MAX610 Summary of contents

... MAX610 connects directly to the 110VAC or 220VAC power line to make a minimum component count 110/220VAC to 5VDC power supply. The devices in the MAX610 family differ in three respects: full- or half-wave rectification, 12V or 18V zener voltage, and the assignment of pin 4 to the function of setting the output voltage or setting the time delay. The MAX610 has ...

... V- to the power line. Note that for a given amount of out- put current, the value of C1 must be twice the value used in the full-wave circuit of Figure 3. As with all MAX610 family circuits that do not use a transformer to isolate the circuit, this circuit is NOT ISOLATED from the power line. ...

... The maximum input voltage to the MAX610 is 10V, and the MAX610 can supply any out- put voltage from 1.3V to 9V. The output voltage of the standard MAX610 is set to 5V ±4% with an undervoltage trip point of 4.65V and an overvoltage trip point of 5.4V. Other output voltages are available through fusible link programming. The overvoltage and undervoltage trip points are fixed at 107% and 93% of the pretrimmed output voltage ...

... DELAY (in sec) Figure 9a. Power-Up Reset Delay Figure 11 shows a simple way to combine a MAX610 with a battery to form an uninterruptible 5V power sup- ply. When the 110VAC line voltage is present, resistor R2 trickle charges the 7.2V NiCd battery. When the 110VAC is removed, the NiCd battery will supply cur- rent through diode D1, and the MAX610 output will remain a constant 5V ...

... MAX612 corrects the battery polarity. The MAX612 is well suited for battery-powered circuits since its quiescent current is only 70µA. The MAX610 can also be used if the battery voltage is less than 10V. The +6.7V open circuit or float voltage of Figure 13 is set by R2 and R3 ...

... Figure 13. Simple Battery Charger The current-limiting resistor (R1) limits the maximum peak current that occurs when power is first applied to the MAX610 just as the power line voltage is at its maxi- mum. The instantaneous peak current must be limited to 5A. For 110VAC, input voltage R1 must be 33Ω or greater ...

... Raw DC Filter Capacitor, C2 The raw DC filter capacitor (C2) is normally an alu- minum or tantalum electrolytic capacitor ordinar- ily 47µF when the MAX610/MAX612 are driven from the 110/220VAC power line. The half-wave MAX611 requires larger values for C2 since the output current is supplied by C2 for one-half of each line cycle. ...

... C2 were discharged into a short cir- cuit below 750µF, this protection is not necessary. 9) While the MAX610 family is stable without an output filter capacitor good engineering practice to have power-supply bypass capacitors on the output to compensate for the increased output impedance of the MAX610/MAX611/MAX612 at high frequency. A 47µ ...
