Buck-Boost Regulators Employ Ultra-Fast Switching Frequency

Oct. 8, 2008
Pumped for portable consumer, medical, and industrial applications, the ADP2503 and ADP2504 dc/dc converters support switching frequencies at speeds up to 2.5 MHz and regulate voltages above and below the battery output. Their fast switching speed

Pumped for portable consumer, medical, and industrial applications, the ADP2503 and ADP2504 dc/dc converters support switching frequencies at speeds up to 2.5 MHz and regulate voltages above and below the battery output. Their fast switching speed allows designers to use low-cost multilayer inductors that are half the size required by comparable converters. Relying on a proprietary current-mode buck-boost architecture, the devices achieve glitchless mode transitions and reliable transient performance across line and load. They also feature a no-load quiescent current of 38 µA in power-save mode. The ADP2503 and ADP2504 operate from input voltages ranging from 2.3V to 5.5V and deliver fixed output voltages from 2.8V to 5V. Available now in 10-lead, 3 mm x 3 mm LFCSP packages, pricing is $1.40 each/1,000. ANALOG DEVICES, INC., Norwood, MA. (800) 426-2564.
