What are the ways to make a dual power supply from a single voltage

If a supply of twice the required minimum voltage is available, another option is to simply split the supply and create a virtual ground, either using an op-amp fed from a pair of matched resistors as voltage divider, or using a dedicated rail splitter part such as the Texas Instruments TLE2426.

Dual Power Supply from Single Battery

A dual power supply is a regular direct current power supply. It can provide a positive as well as a negative voltage and ensures a stable power supply to the device as well as helps to prevent system damage.

6 FAQs about [Convert lithium battery single voltage to dual voltage]

What if a supply is twice the required minimum voltage?

How do you use a dual power supply?

For a quick and simple dual power supply, use two resistors in series connected in parallel with two capacitors. Connect the two ends to the battery or power source and BAM! You have a dual power supply. Typical values for bipolar converters like this are 100k-1M for the resistors and 47uf to 4700uf depending on the current draw of your circuit.

Can ltc3552 supply a battery with a 5V supply?

Example: An LTC3552 operating from a 5V supply is programmed to supply 800mA full-scale current to a discharged Li-Ion battery with a voltage of 3.3V. For sim-plicity, assume the regulators are disabled and dissipate no power.

What is a good droop voltage for a Li-ion battery?

For a 5% output droop: A good standard value is 10μF. Since the impedance of a Li-Ion battery is very low, CIN is typically 10μF. The output voltage can now be programmed by choosing the values of R1 and R2. To maintain high effi ciency, the current in these resistors should be kept small.

What is a good voltage for a switching regulator?

A good rule of thumb for ITERMINATE is one tenth the full charge current, so RITERM is picked to be 1.24k (ITERMINATE = 80mA). For the switching regulator, VCC will be operating from a maximum of 4.2V down to about 2.7V. The load requires maximum of 800mA in active mode and 2mA in standby mode. Regulator 1 output voltage is 1.8V.

What is a good CIN value for a Li-ion battery?

COUT selection is then based on load step droop instead of ESR requirements. For a 5% output droop: A good standard value is 10μF. Since the impedance of a Li-Ion battery is very low, CIN is typically 10μF. The output voltage can now be programmed by choosing the values of R1 and R2.
