ADP5054 High-Performance Power Regulators for Medical, Security, and Surveillance

Analog Devices’ ADP5054 quad buck (step-up) regulators are offered in a small 7 mm x 7 mm 48 LFCSP package

Image of Analog Devices ADP5054 High-Performance Power Regulators for Medical, Security, and SurveillanceADI’s ADP5054 combines four high-performance buck (step-up) regulators in a small 7 mm x 7 mm 48-lead LFCSP package. The switching frequency of the ADP5054 can be programmed or synchronized to an external clock from 250 kHz to 2 MHz, and individual ½x frequency configuration is available for each channel. The ADP5054 contains an individual precision enable pin on each channel for easy power-up sequencing. The internal low 1/f noise reference is implemented in ADP5054 for noise sensitive applications. The device enables direct connection to high input voltages up to 15.5 V with no pre-regulators.
