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.
