The AAT1541 is an integrated power solution tailored for AMOLED and mobile devices. It includes a Boost and an inverting switching regulator operating at 1.5MHz and for VIN ranging from 2.3V to 5.5V. Output voltage of the Boost regulator can be adjusted from 4.6V to 7V through external feedback resistors, and the regulator is implemented with true-shutdown function to eliminate possible power loss during off mode. The inverting regulator output can also be adjusted from –5V to –1.5V. Both regulators are synchronous converters with internal compensation, thereby reducing external part count to minimal.
