Other Parts Discussed in Thread: LP5811
Tool/software:
I submitted datasheet feedback on this but figure I will ask here as well.
LP5810 is a linear 4-channel LED driver. LP5811 is a boost 4-channel LED driver in the same family.
I'm trying to check what decoupling capacitance is recommended for the Vdd pin of LP5810.
The schematic on page 1 and page 23 (application circuit, section 9.2) show 1uF.
Page 24 (section 9.2.3.1) says "While a 10μF input capacitor is sufficient for most applications, large capacitance is used to reduce input current ripple. "
Page 5, Table 5-1 says of the Vcc pin "Boost converter output. A 22 uF capacitor is recommended to be connected between this pin with GND and be placed as close to the device as possible."
I assume this is an error.
What is the recommended input capacitor value for LP5810: 1uF, 10uF, 22uF?
