3A, 30V, 340KHz 车充DC/DC降压方案 CX8505，CX8506，8508，8509,WS5203

产品概述：

The CX8505 is a synchronous current mode buck
regulator capable of driving 3A continuous load current
with excellent line and load regulation. The CX8505
can operate with an input range 4.5V to 30V and the
output can be externally set from 0.925V to 20V with a
resistor divider.   
Fault condition protection includes cycle-by-cycle
current limiting and thermal shutdown. In shutdown
mode the regulator draws 1μA of supply current.
Programmable soft-start minimizes the inrush supply
current and the output overshoot at initial startup.
The CX8505 require a minimum number of external
components.
