The ADP1822 regulated output can track another power supply and can be dynamically adjusted up or down with the controller’s margining-control inputs, making it ideal for high reliability applications. It is well suited for a wide range of high power applications, such as DSP power and processor core power in telecommunications, medical imaging, high performance servers, and industrial applications. It operates from a 3.7 V to 5.5 V supply with power input voltage ranging from 1.0 V to 24 V.
The ADP1822 can operate at any frequency between 300 kHz and 1.2 MHz, either by synchronizing with an external source or an internally generated, logic-controlled clock of 300 kHz or 600 kHz. It includes an adjustable soft start to allow sequencing and quick power-up while preventing input inrush current. Output reverse-current protection at startup prevents excessive output voltage excursions. The adjustable, virtually lossless current-limit scheme reduces external part count and improves efficiency.
The ADP1822 operates over the −40°C to +125°C junction temperature range and is available in a 24-lead QSOP package.
