MAXREFDES1123, 80V/5mA, High-Voltage, Compact Boost Power Supply Reference Design Using MAX1523

MAXREFDES1123, Reference Design is a compact boost power-supply design for high-voltage applications with low current requirements where extremely low cost and small size are top priorities. This design provides an 80V output and up to 5mA of load current. This power supply is designed specifically to provide a simple application circuit at high voltage and to minimize the size and number of external components, making it ideal for low-cost consumer electronics applications. This design is centered around the MAX1523 simple SOT23 boost controller. The design is tested at 5V nominal voltage input. The output voltage is within 1% error margin
