GL2574A Datasheet | Gleam

Description GL2574A of regulators provides all the active functions for a step-down (buck) switching regulator, and drives 1.5A load with excellent line and load regulation. GL2574A is available in fixed output voltages of 3.3V, 5V, 12V, 15V, and a versatile Adjustable output version. These regulators are simple to use and require a minimum number of external ponents. Features include internal frequency pensation and a fixesfrequency oscillator. The GL2574A is high-efficiency replacements for popular three-terminal linear regulators, and is requiring a smaller heatsink or even no heatsink. GL2574A performs well with standard inductors from several manufacturers, and simplifying the design of switch-mode power supplies. GL2574A guarantees ±4% tolerance on output voltage within specified input voltages and output load conditions, and ±10% on the oscillator frequency. External shutdown is included...
