The device can provide 2A output current from a 4.75V to 23V input supply. The AIC2822’s current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and capacitors. Current mode control also provides cycle-bycycle current limit. The AIC2822 provides over voltage protection and thermal shutdown. An adjustable soft-start prevents inrush current during turn on. This device is available in a SOP-8 package, provides a very compact system solution with minimal external components and PCB area.  TYPICAL APPLICATIONS CIRCUIT AIC2822 Typical Application Circuit Analog Integrations Corporation Si-Soft Research Center TEL: 886-3-5772500 FAX: 886-3-5772510 DS-2822G-03 20120807 www.analog.com.tw 1  PIN CONFIGURATION AIC2822-XXXX XX PACKING TYPE TR: TAPE & REEL TB: TUBE P.
