Part Number: PMP10236 Hi Team,
Good day, one of our customer want to use PMP10236 as reference and want to know the reason why bulk capacitors for high bus voltage uses resistor such as 4.7Mega ohm in the design.
Thank you and looking forward for your…
Other Parts Discussed in Thread: UCC28722 , PMP10236 hi engineers.... pls suggest best cost effective and compact topology for input range 85VAV to 440VAC, 50Hz that consume max 60W output power with isolated. Assume output voltage is 12V
Other Parts Discussed in Thread: PMP10236 Dear All,
Need help to suggest suitable power supply reference design for below specs

Part Number: UCC28722 Other Parts Discussed in Thread: PMP10236 Hello UCC28722 Team,
We are using UCC28722 to generate 5V@ 50mA and +/-12V@ 30mA .
The input voltage range is 85VAC to 440VAC, 50/60Hz
But we have few issues-
1. Start-up issues
2. If it start…
