Electrical Characteristics
(1) (2)
Limits in standard typeface are for TJ = +25° C. Limits in boldface type apply over the full operating junction temperature
range (-40°C
≤ TJ ≤ +110°C). Unless otherwise noted, specifications apply to the LM3551 and LM3552 Typical Application
Circuit (pg. 1) with: VIN = 3.6V, V(SD) = 0V for LM3551 and V(EN) = VIN for LM3552, ILOAD = 0A

(1)
All voltages are with respect to the potential at the GND pin.
(2)
Min and Max limits are guaranteed by design, test, or statistical analysis. Typical (Typ) numbers are not guaranteed, but do represent
the most likely norm. Unless otherwise specified, conditions for Typ specifications are: VIN = 3.6V and TA = 25ºC.
(3)
CIN and COUT,: Low-ESR Surface-Mount Ceramic Capacitors (MLCCs) used in setting electrical characteristics
(4)
Duty cycle affects current limit due to ramp generator.
(5)
Current limit at 0% duty cycle. See TYPICAL PERFORMANCE section for Switch Current Limit vs. VIN
(6)
