The LM3311SQ-HIOP is a step-up PWM DC/DC converter designed for applications requiring adjustable output voltage up to 20V. It features an integrated low dropout linear regulator (LDO) and an operational amplifier capable of sourcing/sinking up to 200mA of current. The device operates within a voltage range of 2.5V to 7V and includes a low R_DSON internal switch rated for 2A, enhancing efficiency. The switching frequency is selectable between 660kHz and 1.28MHz, allowing for the use of smaller external components. Additional features include adjustable soft-start functionality, input undervoltage protection, and over-temperature protection. The LM3311SQ-HIOP is housed in a compact 24-lead WQFN package, making it suitable for portable applications and TFT bias supplies.
