FAN5066数据手册集成电路（IC）的PMIC-稳压器-DCDC开关式控制器规格书PDF

描述 Description

The FAN5066 is a synchronous mode DC-DC controller IC which provides an adjustable output voltage for ultra-low voltage applications, down to 400mV. The FAN5066 uses a high level of integration to deliver load currents in excess of 19A from a 5V source with minimal external circuitry. Synchronous-mode operation offers optimum efficiency over the entire output voltage range, and the internal oscillator can be programmed from 80KHz to 1MHz for additional flexibility in choosing external components. The FAN5066 also offers integrated functions including a four-bit DAC-controlled reference, Power Good, Output Enable, over-voltage protection and current limiting.
