• Manufacturer Part Number: MAX610
• Description: AC-to-DC Regulator(110/220VAC to 5.0VDC)
• Manufacturer: MAXIM [Maxim Integrated Products]

With 110VAC, 60Hz input:
Pd (R1) = 1.6 x C1
(in mW)
With 220VAC, 50Hz input:
Pd (R1) = 2.7 x C1
(in mW)
The raw DC filter capacitor (C2) is normally an alu-
minum or tantalum electrolytic capacitor. C2 is 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.
The reset delay capacitor, labeled C3 in Figure 9a, is
non-critical and is usually a low-cost ceramic capacitor.
