AIC2832中文资料2A 16V 490kHz PWM/PSM Synchronous Step-Down Converter数据手册AIC规格书

描述 Description

The AIC2832 is a high efficiency, monolithic syn-chronous step-down DC/DC converter that can deliver up to 2A output current from 4.5V to 16V input voltage.The AIC2832 current mode archi-tecture provides fast transient response and eas-es loop stabilization. Low output voltage ripple and small external inductor and capacitors sizes are achieved with 490kHz switching frequency.

The AIC2832 has cycle-by-cycle current limit provides protection against shorted output, and soft start eliminates inrush current during start-up.

The AIC2832 also provides over voltage protec-tion and thermal shutdown protection function. The low current at shutdown mode allows output disconnection, enabling easy power manage-ment 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.
