The AAT1401IUQ-T1 is a DC-DC regulator specifically designed for driving LEDs. It uses a step-up (boost) topology to provide an output voltage up to 28V from a low input voltage range of 2.7V to 5.5V. The device can deliver a maximum output current of 31mA, making it suitable for driving up to 6 series LEDs. It operates at a fixed switching frequency of 1MHz, allowing the use of small external components. The typical operating current is 2.3mA, and the shutdown current is less than 1µA. Efficiency can reach up to 85%. PWM dimming is supported for brightness control. The device is available in a 10-bump WLCSP package (10WLCSP) for compact designs. It is ideal for portable devices and battery-powered applications where space is limited.
