L6725ATR

DC DC Switching Controllers Overview

The L6725ATR is a voltage-mode PWM controller designed for non-isolated buck converter topologies. It operates within an input voltage range of 4.5 V to 18 V and supports switching frequencies up to 550 kHz. The device features a minimum ON time shorter than 100 ns, enabling very low duty cycles. It provides a programmable output with a reference voltage of 600 mV and a maximum output current capability of 20 mA. The component functions in a temperature range from -40 °C to +85 °C and is housed in a 16-pin SOIC package.
