Texas Instruments SIMPLE SWITCHER® LM2598SX-3-3 is a 1A, 3.3V fixed output voltage, step-down (buck) switching regulator. This monolithic IC integrates a switch, oscillator, voltage reference, and control circuitry, simplifying power supply design. The LM2598SX-3-3 operates with an input voltage range of 4.5V to 40V and features a switching frequency of 150kHz. It is packaged in a TO-263 (DDPAK-7) surface-mount package, supplied on tape and reel. This component is suitable for applications requiring efficient DC-DC conversion, including industrial power supplies, point-of-load converters, and battery-powered systems. The output is configured as positive, and the device utilizes a non-synchronous rectifier topology. Operating junction temperature range is -40°C to 125°C.
