工作条件 输入DC电压24V 电池为5节锂电池串联 充电限制电压设置为21V ，原理图和官方推荐一样，
You are right that it does not exist in LTSpice. You could consider working with LTC4009 which does have a model and is somewhat similar.
Alternatively, you can order a demo board for LTC4007 and just work with that.
I want to buy your LTC4009-1 IC and its evaluation board, on the website i see that you offer the evaluation kit as a sample, this is true?
and if i get the evaluation board, i should change the ic for the LTC4009-1?
请问你遇到过这个问题没，输入DC电压24V 电池为5节锂电池串联 充电限制电压设置为21V，给电池充电，电感会啸叫；空载时给电池充电，充满电后，电流会稳定到一个值，带负载给电池充电，充满电后电流一直跳变，原理图和官方推荐一样，求解释
