CONDITIONS
3V < VIN < 5V, FB = IN, ILOAD = 0 to 135mA
4.5V < VIN < 5.5V, FB = GND, ILOAD = 0 to 90mA
0.1V < VFB < (VIN - 0.1V)
0.1V < VFB < (VIN - 0.1V)
VLX = 12V
VSHDN = VIN, VSS = 150mV
VSHDN = VSS = 0
VOUT = 13V

VSHDN = 0, OUT = IN
VOUT = 13V
3V < VIN < 5.5V
(tON = K / VIN)
MAX606
MAX607
2V < (VOUT + 0.5V - VIN) < 8V (see Pulse-
Frequency-Modulation Control Scheme section)
VIN = 3V
VIN = 5.5V
VSHDN = 0 or VIN
VIN = 3V to 5.5V. For VFB below this voltage,
output regulates to 12V.
