目录产品概述 返回TOP The CXSD61005 is a monolithic step-down switch mode converterwith a built-in power MOSFET. It achieves 1.8A output current over awide input supply range with excellent load and line regulation.Currentmode operation provides fast transient response and eases loop stabilization.Fault condition protection includes cycle-by-cycle currentlimit and over temperature protection.

| Pin Name | Pin Function |
| BS | Bootstrap. A 22nF capacitor is connected between SW and BS pins to drive the power switch’s gate above the supply voltage. |
| GND | Ground Pin. Connect this pin to exposed pad. |
| FB | Feedback. An external resistor divider from the output to GND, tapped to the FB pin sets the output voltage. |
| EN | On/Off Control Input. Pull EN above 1.2V and below 5V to turn the device on. |
| VIN | Power Supply Input. Drive 4.5V to 23V voltage to this pin to power on this chip. Connect a 10μF ceramic bypass capacitor between VIN and GND to eliminate noise. |
| SW | Switch Output. Connect this pin to the switch end of the inductor. |
| NC | No Connect. |
