L4993DTR ST PWM Controller | 8-SOIC | 1MHz, 1.5A Gate Driver

Product Overview

The L4993DTR is a high-performance current-mode PWM controller from STMicroelectronics, designed for DC-DC converters and power supplies. It integrates a 1.5A gate driver and operates at up to 1MHz switching frequency, enabling compact and efficient power solutions. The device features a wide input voltage range (8V to 18V) and includes protection functions such as overcurrent, overvoltage, and thermal shutdown. Housed in an 8-SOIC package, it is suitable for space-constrained applications.
