Other Parts Discussed in Thread: TPS61230,
Hello.
I am wanting to use the TPS6109 to have a Vin = 3.8V, Vout = 5.0V. I want the IC to stop operating once Vin = 3.20V - 3.25V. Using the above equations I calculated the needed values of R1 and R2. Is there any calculations that need to be done to calculate the pull up resistor for the LBO pin or is the 1M ohm value for the pull resistor the needed resistor value regardless of what Vin we want the IC to shut off at?
In other words is the 1M ohm pull up resistor for the LBO pin fixed and the value of R1 is the only value that needs to be changed to have the IC shut off at a specific value of Vin?
Thank you for any help you can give in this matter.
