Post as a guest Name. With the black wires as the common ground. Some ICs are particularly useful for certain circuits, such as the ICL charge pump for getting a negative voltage from a single voltage input, creating a split power supply as needed for many analog or ternary circuits.

Industrial Control and Automation. Nils Pipenbrinck 4, 1 8 MyMaxim My Maxim logout. Input Voltage Min V. Legal Privacy Policy Sitemap. Edesign yes, measure resistance between adjecting IC pins and the capacitor pins.

Setting the oscillator to 40Hz, for example, by connecting pF to pin 7 icl766 the highest efficiency possible. Please check latest availability status for a specific part variant.

Medical Diagnostics Monitoring and Therapy. Output Voltage Min V.

Lower Operating Frequency Improves ICL Voltage-Conversion Efficiency – Application Note – Maxim

Adding an oscillator capacitor to the typical ICL application lowers the oscillator frequency, which for lower values of IO results in more efficient icl76600 conversion. USB will provide at least mA, usually mAbut higher requires negotiation. A unique logic icl660 senses the most negative voltage in the device and ensures that the output NChannel switch source-substrate junctions are not forward biased.

They deliver 10mA with a 0. The drop is more than I expected, but hopefully it sufficient for some purposes. Next I soldered on a USB connector, to supply the positive input:.

Now for some more fixed regulators, although these are low-dropoutallowing the input voltage to be quite close ilc7660 the output voltage. This design note shows how to improve the efficiency of a voltage converter by lowering the oscillator frequency.

However, given 5 V input, I get about a 4. This is a fairly decent general-purpose regulator, adjustable voltage and current limit, for a wide variety of usages.
