DP2358,Integrated 600V Power MOSFET Current-Mode PWM Controller,DIP-8

The DP2358 is a high-performance current-mode PWM controller with an integrated 600V power MOSFET, designed for offline flyback converter applications. It provides efficient power conversion with a fixed switching frequency of 65kHz and frequency shuffling to reduce EMI emissions.

To meet stringent energy efficiency standards, the DP2358 features green and burst mode operation, reducing power consumption to less than 75mW during standby. Its advanced protection mechanisms include over-voltage protection (OVP), under-voltage lockout (UVLO), cycle-by-cycle current limiting, and thermal shutdown, ensuring reliable operation in demanding environments.

The built-in slope compensation enhances system stability at high duty cycles, while the leading-edge blanking eliminates premature switching interruptions. Packaged in a DIP-8 format, the DP2358 is ideal for use in power adapters, general-purpose SMPS, and motor driver power supplies.
