Electrical Characteristics
Limits in standard typeface are for TA = +25°C. Limits in boldface type apply over the full operating junction temperature range
(-30°C
≤ TJ ≤ +125°C). Unless otherwise noted: VIN = 3.6V, RSET = 16.5kΩ, VD1 = VD2 = 500mV, VFB bit = '0', FEN = '0', TX =
'0', Flash Current Level = Full-Scale.

(1)
All voltages are with respect to the potential at the GND pin.
(2)
Min and Max limits are specified by design, test, or statistical analysis. Typical (Typ) numbers represent the most likely norm. Unless
otherwise specified, conditions for Typ specifications are: VIN = 3.6V and TA = 25ºC.
(3)
All testing for the LM3553 is done open-loop.
