5 / 16 page Electrical Characteristics (Notes 2, 9, 10) Limits in standard typeface are for T J = 25˚C. Limits in boldface type apply over the full operating junction temperature range (−25˚C ≤ T J ≤ +125˚C). Unless otherwise noted, specifications apply to the LM3671 Typical Application Circuit (Figure. 1) with V IN = EN = 3.6V, VOUT = 1.5V (Continued) Note 8: Refer to datasheet curves for closed loop data and its variation with regards to supply voltage and temperature. Electrical Characteristic table reflects open loop data (FB=0V and current drawn from SW pin ramped up until cycle by cycle current limit is activated). Closed loop current limit is the peak inductor current measured in the application circuit by increasing output current until output voltage drops by 10%. Note 9: Min and Max limits are guaranteed by design, test or statistical analysis. Typical numbers are not guaranteed, but do represent the most likely norm. Note 10: The parameters in the electrical characteristic table are tested at VIN= 3.6V unless otherwise specified. For performance over the input voltage range refer to datasheet curves. Note 11: Input voltage range for all voltage options is 2.8V to 5.5V. The voltage range recommended (Fixed Voltage parts) for ideal applications performance with 500mA or higher output current is given below. VIN = 2.8V to 4.5V for VOUT = 1.2V, 1.25V, 1.375V, 1.5V and 1.6V. VIN = 3.0V to 4.5V for VOUT = 1.8V and 1.875V.
