说明
- MAXREFDES1017, Reference Design for the MAX16990 is a high-performance, current-mode PWM controller with 4uA (typ) shutdown current for wide input voltage range boost/SEPIC converters. The 4.5V to 36V input operating voltage range makes this device ideal in automotive applications such as for front-end (pre-boost) or (SEPIC) power supplies and for the first boost stage in high power LED lighting applications. An internal low-dropout regulator (PVL regulator) with a 5V output voltage enables the MAX16990 to operate directly from an automotive battery input. The input operating range can be extended to as low as 2.5V when the converter output is applied to the SUP input. The MAX16990 operates in different frequency ranges. It can be synchronized to an external master clock using the FSET/SYNC input
