Hello all,
Table 1 shows the I2C address of this device based on CONFIG and DEFSEL pins. The four possible 7-bit addresses are:
0x78; 1111000_
0x79; 1111001_
0x7A; 1111010_
0x7B; 1111011_
Note: "_…
Other Parts Discussed in Thread: LP8725 Hello,
Below is a table from the LP8725 datasheet regarding dynamic voltage scaling for BUCK1. BUCK1 may be controlled with an external pin or with a register bit, yet the table implies that BUCK1 is solely controlled…
Other Parts Discussed in Thread: LP8725 We built a (somewhat) simple proto board to test the LP8725. It contains an MCU (MSP430), a flash chip, an RF chip, and a few others.
Observed behavior is that the LP8725 appears to reset frequently.
Details…
Other Parts Discussed in Thread: LP8725 We are in the process of integrating an LP8725 PMU into our design, and are not sure what to do with 2 of the pins.
Specifically, we're not sure how to connect (or not) PS_HOLD and PWR_ON. We're using PMU mode…
Hi,
I've attached the 2013 User's Guide for power products. Starting on page 53 you will find a selection of PWM controllers. many of these teh frequency can be varied according to external criteria.
As an example if you use a UC3842 it is a simple…
Gary,
Most any of our power controllers with dual output capability will provide the control. See attached document starting at page 50 with the dual output controllers on page 53 and 54 and choose what features you want.
Regards,
John
