设计要求:8v到15v降压到5v, 500mA工作电流。
有三个芯片:
(1)TPS562200 4.5V to 17v Input, Adjustable output 0.76 to 7v, 2-A synchronous step-down, D-CAP2 mode;
(2)TPS62160 3V to 17v Input, Adjustable output 0.9 to 6v, 1-A synchronous step-down, DCS-Control Topology;
(3)RT7250 4V to 17v Input, Adjustable output 0.8 to 12v, 2-A synchronous step-down,
上面三个到底选哪个好?D-CAP2 mode和DCS-Control Topology到底有什么区别? |
