Frequently Asked Questions
What is the minimum input voltage for LM2623?
The LM2623 has an ultra-low startup voltage of 0.8V, allowing direct operation from a single depleted alkaline or NiMH battery cell. Once started, it can continue operating down to 0.6V input, extracting maximum energy from the battery.
What output voltages can LM2623 generate?
The LM2623 can generate adjustable output voltages from the input voltage up to 14V maximum, set by an external resistor divider. Common configurations include 3.3V and 5V from single-cell batteries. Output current capability depends on input/output voltage ratio.
What is the efficiency of LM2623?
The LM2623 achieves up to 90% efficiency in typical applications. Efficiency varies with input/output voltage ratio and load current. At light loads, the automatic power-save mode reduces switching losses to maintain high efficiency across the entire load range.
What external components does LM2623 need?
The LM2623 requires an external inductor (4.7µH-22µH typical), Schottky diode, output capacitor (22µF-47µF), and feedback resistor divider. The 1.3MHz switching frequency allows small inductors, keeping the total solution size compact.
