As a 100V/3A step-down regulator with an integrated high-side MOSFET and a wide input voltage range of 4.0-100V, SY5130 is suitable for industrial and automotive applications with unregulated power supply. It prolongs the battery life by providing an ultra-low current of 9u in shutdown mode. The adjustable switch frequency of 200kH-1MHz provides the optimized efficiency or external component size. The internal loop compensation eliminates the tedious work in design of the loop compensation components and minimizes the external components. Enable pin can withstand high voltage, that makes the timing control design simpler . In addition, there are a variety of built-in protection features: cycle-by-cycle current limit, Over temperature shutdown protection , Over voltage protection and under-voltage protection.
