Hi,
I have made a PCB for a buck converter with a constant 5 V output and maximum output current of 4 A using LM22677-Q1-5.0. The input voltage(battery source) will vary between 6.5 to 8.4 volts. The circuit schematic used was generated by the WEBENCH…
Part Number: LM22677 On a development board, I have two LM22677 buck converters for two different voltage levels (adjustable at 12V, fixed at 5V). As per the datasheet section 7.3.4, the RT/SYNC pins of the two connectors are pulled low with 1k resistors…

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
