TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information 8.1.1 Setting The Output Voltage The LM3269 features a pin-controlled variable output voltage which eliminates the need for external feedback resistors. It can be programmed for an output voltage from 0.6 V to 4.2 V by setting the voltage on the VCON pin, as in Equation 1. VOUT = 3 × VCON (1) When VCON is between 0.2 V and 1.4 V, the output voltage will follow the formula in Equation 1. 8.1.2 Output Current Capacity The LM3269 load capability is as shown in Table 1. Table 1. Output Voltage vs. Maximum Output Current Derating VOUT VBATT MAXIMUM IOUT CAPABILITY > 3 V 650 mA 4.2 V 2.7 V to 3 V 500 mA > 3 V 750 mA 3.8 V 2.7 V to 3 V 600 mA < 1.5 V 2.7 V to 5.5 V 120 mA (in PFM mode) 8.2 Typical Application Copyright © 2011–2015, Texas Instruments Incorporated Submit Documentation Feedback 11 Product Folder Links: LM3269 |
