DESCRIPTION
The AIC2842 is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 2A output current from 4.5V to 16V input voltage.The AIC2842 current mode architecture provides fast transient response and eases loop stabilization. Low output voltage ripple and small external inductor and capacitors sizes are achieved with 1.2MHz switching frequency.
The AIC2842 has cycle-by-cycle current limit provides protection against shorted output, and soft start eliminates inrush current during start-up.
The AIC2842 also provides over voltage protection and thermal shutdown protection function. The low current at shutdown mode allows output disconnection, enabling easy power management in battery-power system.
This device is available in SOT23-6 package provides a very compact system solution with minimal external components and PCB area.
