GENERAL DESCRIPTION
DP2701X is a high performance PrimarySideRegulation (PSR) PWM power switchwithhighprecision CV/CC control ideal for chargerapplications. DP2701X can achieve audio noise freeoperationand fast dynamic response. The built-inCableDrop Compensation (CDC) function canprovideexcellent CV performance. DP2701X integrates functions and protectionsofVDD Under Voltage Lockout (UVLO), VDDoverVoltage Protection (VDD OVP), Cycle-by-cycleCurrent Limiting (OCP), Short Load Protection(SLP), On-Chip Thermal Shutdown, VDDClamping, etc. DP2701X also integrates single failure protections,including FB pull-up resistor open protection, FBpull-down resistor open protection, FBpull-downresistor short protection, output rectifier diodeorSR open protection, output rectifier diodeor SRshort protection, transformer windingsshortprotection and RCS open protection
