100V/2A Non-synchronous Buck Converter with Ultra Low Quiescent Current
SC81A20
The SC81A20/E is a non-synchronous buck converter featuring a wide input voltage range of 6V to 100V, and is specifically optimized for applications demanding ultra-low standby power consumption. The converter can achieve high efficiency and can support up to 2A continuous load current with integrated Low RON high-side power MOSFETs. The SC81A20 integrates a PG pin to indicate whether the output is within the target range, while for the SC81A20E, the PG pin is replaced by an EXT pin instead. The SC81A20E can achieve much lower standby loss and higher light-load efficiency via the EXT tied to VOUT.
