产品概述 返回TOPhDV嘉泰姆
The CXSD61019 is a 180 KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 3.5A load with high efficiency, low ripple and excellent line and load regulation. Requiring a minimum number of external components, the regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator.
The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An over current protection function is built inside.When short protection function happens, the operation frequency will be reduced from 180KHz to 48KHz. An internal compensation block is built in to minimize external component count

| Pin Number | Pin Name | Description |
| 1 | NC | No Connected. |
| 2 | SW | Power Switch Output Pin (SW). SW is the switch node that
supplies power to the output.
(Note: Connected the back exposed PAD to SW.) |
| 3 | GND | Ground Pin. Care must be taken in layout. This pin should be
placed outside of the Schottky Diode to output capacitor
ground path to prevent switching current spikes from inducing
voltage noise into CXSD61019. |
| 4 | FB | Feedack Pin (FB). Through an external resistor divider
network, FB senses the output voltage and regulates it. The
feedback threshold voltage is 1.25V. |
| 5 | EN | Enable Pin. Drive EN pin low to turn off the device, drive it
high to turn it on. |
| 6 | OCSET | Output Constant Current Set Pin. |
| 7 | VC | Internal Voltage Regulator Bypass Capacity. In typical system
application, The VC pin connect a 1uf capacity to VIN. |
| 8 | VIN | Supply Voltage Input Pin. CXSD61019 operates from a 8V to 36V DC voltage. Bypass Vin to GND with a suitably large capacitor to eliminate noise on the input. |
