Page 4: Switching Power Supply
The switching power supply for the ActiveKEY is based on a switchmode buck/boost controller device. For this application the “SEPIC” mode of operation was chosen for high efficiency operation of the regulator circuitry. This device is a low noise high speed controller operating at ~800 KHz that is perfectly suited to the ActiveKEY requirements. -
