产品概述 返回TOP
The CXSU63005 is a constant frequency, 5-pin TSOT23 current mode step-up converter intended for small,low power applications. The CXSU63005 switches at 1.2MHz and allows the use of tiny, low cost capacitors and i nductors 2mm or less in height.Internal soft-start results in small inrush current and extends battery life. The CXSU63005 operates from an input voltage as low as 2.5V and can generate 28V at up to 100mA from a 5V supply.
The CXSU63005 features automatic shifting to pulse frequency modulation mode at light loads. The CXSU63005 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The CXSU63005 is available in a small 5-pin TSOT-23 package.

NAME |
FUNCTION |
|
1 |
SW |
Power Switch Output. SW is the drain of the internal MOSFET switch. Connect the power inductor and output rectifier to SW. SW can swing between GND and 28V. |
|
2 |
GND |
Ground Pin |
|
3 |
FB |
Feedback Input. The FB voltage is 1.25V. Connect a resistor divider to FB. |
|
4 |
EN |
Regulator On/Off Control Input. A high input at EN turns on the converter, and a low input turns it off. When not used, connect EN to the input supply for automatic startup. |
|
5 |
IN |
Input Supply Pin. Must be locally bypassed. |
