Powersafe operation of reg.2 Getting Started al id The AS1336 Demoboard is designed to work with the AS1336A adjustable output voltage version. With the resistor divider R1/R2 it is possible to adjust the “Low Battery Comparator Input” threshold. With the resistor divider R3/R4 it is possible to adjust VOUT1 and with the resistor divider R5/R6 it is possible to adjust VOUT2. On this Demoboard the following resistor values are mounted: R1 = 330k and R2 = 1M
VDETECT = 800mV R3 = 560k and R4 = 180k
VOUT1 = 3.3V R5 = 150k and R6 = 120k
VOUT2 = 1.8V Function Value Description Manufacturer Cin Input Capacitor 10µF 0805 / X5R / 6.3V Murata Cout1 Output 1 Capacitor 10µF 0805 / X5R / 6.3V Murata Mfg. Order Nr.
