SF2500
The SF2500 is a high-performance, highly integrated DCM (Discontinuous Conduction Mode) primary-side regulation (PSR) power switch suitable for offline low-power converter applications. It can achieve CV/CC accuracy below ±4%. The SF2500 integrates a proprietary NC-Cap/PSR-IITM series for CV control, eliminating the need for external compensation or filter capacitors. Built-in cable voltage drop compensation provides superior CV performance. The IC uses multi-mode control to improve efficiency and reliability and reduce audio noise energy at light loads. The IC achieves standby power consumption below 70mW. The SF2500 integrates proprietary "audio noise reduction" control for audio noise-free operation. The IC features built-in "fast dynamic response" control to meet USB charging requirements. The SF2500 also integrates proprietary "zero-output start" control to enable startup when the output voltage is near zero. The IC features proprietary "intelligent output short-circuit protection" to protect systems with large leakage inductance during output short circuits. The SF2500 integrates FB short-circuit protection, undervoltage lockout (UVLO), VDD overvoltage protection (VDD OVP), soft start, cycle-by-cycle current limit (OCP), pin float protection, and VDD clamping functions and protections. The SF2500 is available in an SOP8 package.
