U6205SC Datasheet | UNI SEMI

Description U620XC is a high performance current mode PWM power switch for offline flyback converter applications. The IC has built-in General Primary Side CC control, which simplifies isolated power supply design that requires CC regulation of the output. In U620XC, PWM switching frequency with shuffling is fixed to 65KHz and is trimmed to tight range. The IC has built-in green and burst mode control for light and zero loadings, which can achieve less than 75m W standby power . - Features - General Primary Side Constant-Current (CC) Control Supports DCM and CCM Operation - ±5% CC Regulation , ±1% CV Regulation with Fast Dynamic Response - CC Algorithm pensates for Line Variation and Transformer Inductance Tolerance - Less than 75m W Standby Power - Current Mode Control - Built -in Frequency Shuffling - Fixed 65KHz Switching Frequency - Green Mode and Burst Mode Control - On-chip Thermal Shutdown - Cycle -by-Cycle Current Limiting U620XC integrates functions and protections of Under Voltage Lockout (UVLO), VDD over Voltage Protection (VDD OVP), Cycle-by-cycle Current Limiting (OCP), Short Load Protection (SLP), Over Load Protection (OLP), On-Chip Thermal Shutdown (OTP), Soft Start, VDD Clamping, etc. - Built -in Leading Edge Blanking - Built -in Slope pensation - Very Low Startup and Operation Current - Package: U6202SC：SOP-7 U6203SC: SOP-7 U6205SC: SOP-7 U6205DC: DIP-7 - Applications - Package Information - Chargers and Adapter - Motor Driver Power Supply - Remended Output Power(1) Part Number 90~264Vac 175-264Vac U6202SC 5W 7.5W U6203SC 10W 12W 12W 15W U6205DC 20W 24W Note 1:Typical continuous power in a non-ventilated enclosed adapter with sufficient drain pattern as a heat sink at 40 ℃ ambient. - Ordering Information TOP...
