The AAT1403IUQ-T1 from Skyworks Solutions is a single-channel, step-up (boost) LED driver IC. It is designed for applications requiring efficient LED backlight solutions, such as in mobile handsets and portable media players.
This device features a wide input voltage range of 2.7V to 5.5V and can deliver an output voltage of up to 45V with a typical output current of 31mA. It operates at a high switching frequency of 1MHz, which allows for the use of small, low-cost external filtering components. The AAT1403IUQ-T1 supports PWM dimming control and offers advanced features like over-temperature protection and programmable over-voltage protection.
The LED driver is available in an ultra-small, low-profile 10-pin WLCSP package, measuring 1.55 x 1.15mm, making it suitable for space-constrained designs. It operates over a temperature range of -40°C to +85°C.
Key electrical specifications include a typical operating current of 2.3mA and a shutdown current of less than 1µA. The device also offers dimming control options including 32 steps via S2Cwire interface and filtered PWM control.
