BD9615MUV-LB
3.5V to 60V Input 1ch Boost DC/DC Controller

This is the product guarantees long time support in Industrial market. BD9615MUV-LB is a low side MOSFET controller with high withstand voltage (60V). It is suitable for circuits requiring low side FET such as boost and flyback, and it can be used in various applications. An external resistor can adjust the switching frequency from 100kHz to 2500kHz. It reduces the total mounting area because It can operate at extremely high switching frequency. In addition, it has an external clock synchronization function to perform noise management. BD9615MUV-LB has Thermal Shutdown (TSD), Over Voltage Protection (OVP), and Over Current Protection (OCP) to prevent damage caused by various abnormal modes.
