GENERAL DESCRIPTIONDP2358 is a high performance current modePWMpower switch for offline flyback converterapplications.

In DP2358, PWM switching frequencywithshuffling is fixed to 65KHz and is trimmedtotight

range. The IC has built-in green and burst modecontrol for light and zero loadings, whichcanachieve less than 75mWstandby power. DP2358 integrates functions and protectionsof

Under Voltage Lockout (UVLO), VDDoverVoltage Protection (VDD OVP), Cycle-by-cycleCurrent Limiting (OCP), Over Load Protection(OLP), On-Chip Thermal Shutdown (OTP), Soft

Start, VDD Clamping and CS Pin Float Protection, etc.
