Cxle8135 is a constant frequency, 5-pin sot package, current mode boost converter for low-power applications. The switching frequency of cxle8135 is 1.0mhz, allowing the use of smaller low-cost capacitors and inductors of 2mm or less height. Internal soft start reduces surge current and prolongs battery life. The input voltage of cxle8135 is as low as 3.0V, and 5V input can provide 20V current up to 100mA. Cxle8135 adopts automatic pulse frequency mode when it is light loaded. Cxle8135 features also include current limiting and overcurrent protection to prevent chip damage in the event of output overload
