This file is a user manual for a certain brand and model product, which introduces the characteristics of the product.
The SG1825C family (SG1825C, SG2825C, SG3825C) are high‑performance current‑limit comparators and PWM controllers designed for current‑mode power supplies and oscillator applications. They feature a wide‑band low‑impedance error amplifier, programmable soft‑start, and a range of package options.
Key specifications include a 10‑30 V supply range, up to 1.5 A peak output current, and an oscillator frequency that can be programmed from 4 kHz to 1.5 MHz. The document also provides detailed pin‑out diagrams, thermal data, absolute maximum ratings, and application circuits for layout and bypassing.
