Other Parts Discussed in Thread: BQ24773
Above is a scope of the startup of boost based on the TPS61236P. the circuit quickly rises to the input voltage. Hangs there about 8 seconds and then slowly begins to rise to the 5V output. This circuit is being feed off the Sys output voltage of a bq24773 battery charger chip. The battery charger is not charging while we are booting. I am running solely off battery.
The 5V output has the following capacitors attached.
1 10uF
1 4.7uF
3 22uF
1 47uF
C total 127.7uF
the 5V power supply input comes off the sys power output from the battery charger. Schematics can sent in private message.
