The SG3524M/TR with SOP-16 AC-DC Controllers & Regulators ROHS manufactured by HGSEMI is a high-frequency pulse-width modulation controller designed to offer improved performance and reduced total power loss. It features an internal digital circuitry which provides precision peak current control and pulse-width modulation. Additionally, it has an internal under-voltage lockout and thermal shutdown circuit which helps protect the device. The SG3524M/TR is well-suited for applications such as on/off control, as well as LED dimming, high-efficiency, switched-mode power supplies, and motor speed control. It is RoHS compliant and can operate from a supply voltage range of 4.5V to 40V.
