L6727TR ST PWM Controller | 8-SOIC | 5V-12V Input, 300kHz-1MHz

Product Overview

The L6727TR is a high-performance PWM controller from STMicroelectronics, designed for DC-DC step-down (buck) converter applications. It operates from a 5V to 12V input voltage range and provides a regulated output voltage as low as 0.8V. The device features a fixed frequency oscillator programmable from 300kHz to 1MHz, allowing optimization between efficiency and component size. Housed in a compact 8-SOIC package, the L6727TR integrates a high-gain transconductance error amplifier, a precision reference, and protection features such as overcurrent and undervoltage lockout. Its adaptive non-overlap circuitry prevents cross-conduction, enhancing reliability. This controller is ideal for point-of-load regulation in networking, telecom, and industrial systems.
