TI中文支持网Hi，
1.TPS51120的current mode和D-Cap模式具体差异是什么？
2.这两种模式在输出电容的选择上有什么区别？
3.输出电容的ESR太小了会影响环路稳定吗？
谢谢！
Johnsin Tao：
Hidatasheet 第22页7.4有详细描述，你可以看看。The current mode option has relatively higher flexibility by the external compensation network provided to the COMP pin. And it is suitable for lowest ripple design with output capacitor(s) having ultra-low ESR. Although D-CAP mode provides many advantages such as ease-of-use, minimum external components configuration and extremely short response time, due to not employing an error amplifier in the loop, sufficient amount of feedback signal needs to be provided by external circuit to reduce jitter level.
