ZHCSH22C January 2009 – November 2017 LM3241
PRODUCTION DATA.
The LM3241 features a pin-controlled adjustable output voltage to eliminate the need for external feedback resistors. The output voltage can be programmed for an output voltage from 0.6 V to 3.4 V by setting the voltage on the VCON pin, as shown in Equation 1.
When the VCON voltage is between 0.24 V and 1.36 V, the output voltage follows proportionally by 2.5 times of VCON.
If the VCON voltage is less than 0.24 V (VOUT = 0.6 V), the output voltage may be regulated (for details see Figure 17). Figure 17 exhibits the characteristics of a typical part, and the performance cannot be ensured as a part-to-part variation could occur for output voltages less than 0.6 V. For VOUT lower than 0.6 V, the converter could suffer from larger output ripple voltage and higher current limit operation.
