AIC2833中文资料3A 16V 490KHz PWM/PSM Synchronous Step-Down Converter数据手册AIC规格书

描述 Description

The AIC2833 is a high efficiency, monolithic synchronous step-down DC/DC converter that can deliver up to 3A output current from 4.5V to 16V input voltage.The AIC2833 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 490KHz switching frequency.

The AIC2833 has short circuit protection function provides protection against shorted output, and soft start function eliminates inrush current during start-up.

The AIC2833 also provides 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 TSOT23-6 package provides a very compact system solution with minimal external components and PCB area.
