Guangdong's new SC2987 core source is a PWM buck converter, the typical output drive current of 3.8A without external transistors. Design allows it to operate over a wide input voltage of 8V ~ 48V. By COMP / EN pin is pulled low logic level to control external shutdown, it goes into standby mode. External compensation allows the feedback control has a good line regulation and load regulation, with a flexible peripheral design. One of the features is the SC2987 has a programmable CV / CC mode control. CV (constant voltage) mode provides a stable output voltage, CC (constant current) mode provides a limiting function. During the current sense amplifier input, CC current value is set by external resistors. SC2987 is suitable for the need to use the current limiting function of DC / DC switching power supply. The device uses ESOP-8L package and requires only a few external components work. Luo widely core source
