ELECTRICAL CHARACTERISTICS (continued)
(V OUT = 5V, I LOAD = 0mA, T A = -40°C to +85°C where indicated. T A = -25°C to +85°C for all other limits. Typical values are at
T A = +25°C.)

Note 1: Limits over this temperature range are guaranteed by design.
Note 2: The MAX608 must be operated in bootstrapped mode with OUT connected to the DC-DC circuit output. The minimum output
voltage set point is +3V.
Note 3: Output voltage guaranteed using preset voltages. See Figures 4a–4d for output current capability versus input voltage.
Note 4: Output voltage line and load regulation depend on external circuit components.
Note 5: Operation in the external-feedback mode is guaranteed to be accurate to the V FB trip level, and does not include resistor tolerance.
