前輩,謝謝你的回答.我VDD range 在spec.裡是1.2V,小弟有考慮過前輩你們的建議0.6~1.2V,但error amplifier用p-channel就會有風險.請問有人在PWM booster的應用上取0.2V~0.3V來做Vfb嗎?我的主管不想做第一隻老鼠,我實在找不出理由堅持用0.2V.
For power ic, the reference voltage is 0.8V not your 1.2V.
and for the closed loop , the error amp must connect to the negative feedback so that the power system may ne stable.
