SiLM6582/83 series
95V, 0.5A DC-DC buck converter
SiLM6582/83 is a high conversion efficiency synchronous buck DC-DC that can provide an output current of 0.5 A. SiLM6582/83 operates within a wide input voltage range of 6V to 95V and integrates extremely low impedance switching transistors to minimize power loss and provide an efficient voltage conversion solution.
SiLM6582/83 adopts a control architecture with constant on-time switching to achieve fast transient response. The ultra-low static current and diode operating mode improve efficiency under light loads. SiLM6582/83 provides internal soft start to limit startup surge current. The programmable UVLO pin provides a flexible way to program the startup input voltage and good output of the open drain power supply to indicate the health status of the regulator. Simultaneously integrated with peak valley current limiting protection and over temperature protection.
