ELECTRICAL CHARACTERISTICS
(VIN = SHDN = 3V, FREQ = GND, TA = -40°C to +85°C, unless otherwise noted.) (Note 2)
Note 1: Current limit varies with duty cycle due to slope compensation. See the Output Current Capability section.
Note 2: Specifications to -40°C are guaranteed by design and not production tested.

CONDITIONS
FREQ = GND
Level to produce VCOMP = 1.24V
FREQ = IN
SHDN = GND
VFB = 1.0V, switching
VFB = 1.24V
Level to produce VCOMP = 1.24V,
2.6V < VIN < 5.5V
FREQ = GND
∆I = 5µA
VFB = 1V, duty cycle = 65%
ILX = 1.2A
VIN rising, typical hysteresis is 40mV,
LX remains off below this level
SHDN, FREQ, VIN = 2.6V to 5.5V
SHDN, FREQ, VIN = 2.6V to 5.5V
VFB = 1.3V, not switching
