Note 1:
Output voltage is specified at 1A switch current I
SW
, which is equivalent to approximately 1A
(V
IN
/ V
OUT
) of load current.
Note 2:
Load regulation is measured by forcing specified switch current and straight-line calculation of change in output voltage in
external feedback mode. Note that the equivalent load current is approximately I
SW
(V
IN
/ V
OUT
).
Note 3:
Until undervoltage lockout is reached, the device remains in startup mode. Do not apply full load until this voltage is
reached.
Note 4:
Startup is tested with Figure 1
’
s circuit. Output current is measured when both the input and output voltages are applied.
Note 5:
Minimum operating voltage. The MAX1709 is bootstrapped and will operate down to a 0.7V input once started.
Note 6:
Supply current is measured from the OUT pin to the output voltage (+3.3V). This correlates directly with actual input supply
current but is reduced in value according to the step-up ratio and efficiency.
Note 7:
ONA and
ONB
inputs have approximately 0.15V hysteresis.
Note 8:
Guaranteed by design, not production tested.
Note 9:
Specifications to -40
°
C are guaranteed by design, not production tested.
