The AAT1145IDE-1.8-T1 from Skyworks Solutions is a 1.2MHz constant frequency, current mode PWM step-down (buck) converter designed for portable equipment. It can supply up to 1.5A of output current from a 2.5V to 5.5V input voltage, with a fixed output voltage of 1.8V.
This converter features high efficiency, achieving over 90% during peak load conditions. It also supports low dropout operation with 100% duty cycle, extending battery life in portable systems. The high switching frequency minimizes external component size while maintaining low switching losses. Internal slope compensation allows for the use of smaller inductor values for optimized size and efficiency.
The AAT1145IDE-1.8-T1 includes features such as soft start, short-circuit protection, and thermal fault protection. It has a low shutdown current of less than 1μA. The device is available in a Pb-free, 3 x 3mm 10-lead TDFN package and is rated for an operating temperature range of -40°C to +85°C.
Applications include cellular phones, digital cameras, DSP core supplies, PDAs, portable instruments, and smartphones.
