AA18375数据手册Agamem中文资料规格书

描述 Description

The AA18375 is a two-channel PWM DC-DC converter control IC that features low-voltage operation. This IC can obtainthe step-up, step-down and inverting voltages with a small number of external components. Because the IC iscompactly packaged, it is best suited for use as a power supply in portable equipment.
