Other Parts Discussed in Thread: LM22674, TEST
Hi TI teams,
When we use LM22676 or LM22674, we design the circuit as below, the FB signal is from the MCP6002. The output voltage is changed following the DAC output signal.
But when we PP the product, and do test, LM22676 burn up when the system is power up. The failure rate is about 10%, and when finish power up , the system is steady. Can you help to check whether the circuit is OK ? and pls. give some advise. thanks
