4 / 22 page LM2759 SNVS577D – JUNE 2008 – REVISED MAY 2013 www.ti.com 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 (-30°C ≤ TJ ≤ +125 °C). Unless otherwise noted, specifications apply to the LM2759 Typical Application Circuit (pg.1) with VIN = 3.6V, VTX = 0V, VSTROBE = 0V, CIN = C1 = C2 = 2.2 µF, COUT = 4.7 µF.

(2) Min and Max limits are specified by design, test, or statistical analysis. Typical (Typ) numbers are not ensured, but do represent the most likely norm. Unless otherwise specified, conditions for Typ specifications are: VIN = 3.6V and TA = 25°C. (3) CIN, COUT, C1, C2: Low-ESR Surface-Mount Ceramic Capacitors (MLCCs) used in setting electrical characteristics. (4) For input voltage below the regulation target during the gain of 1x, the output voltage will typically be equal to the input voltage. (5) SCL and SDA should be glitch-free in order for proper brightness control to be realized. 4 Submit Documentation Feedback Copyright © 2008–2013, Texas Instruments Incorporated Product Folder Links: LM2759 |
