Categories: DC DC Switching Controllers
Quality Control: Learn More
Fairchild Semiconductor FAN1577AMX is a Dual Switching Controller designed for positive output step-down DC-DC conversion. This 20-SOIC package IC operates with a voltage supply range of 8V to 15V and features a maximum duty cycle of 90% at a switching frequency of 340kHz. The FAN1577AMX supports two outputs, each configured as a positive output with a transistor driver output type, and utilizes a Buck topology. Key control features include Enable, Frequency Control, and Soft Start. This component is suitable for applications requiring synchronous rectification and is presented in Bulk packaging. It is commonly found in power supply designs for consumer electronics and industrial control systems.
