OB5269 is a high-performance current mode PWM controller with integrated HV start-up ，optimized for high performance, low standby power and cost effective offline flyback converter applications. VDD low startup current and low operating current contribute to 100mW input power on standby design. OB5269 offers complete protection coverage with auto-recovery including Cycle-by-Cycle current limiting (OCP), over load protection (OLP), and VDD under voltage lockout (UVLO). It also provides the protections with latched shut down including over temperature protection (OTP), and over voltage (fixed or adjustable) protection (OVP).
Features:
◆ High Voltage Startup Circuit
◆ Ultra Low Standby Power
◆ Power on Soft Start Reducing MOSFET Vds Stress
◆ Frequency shuffling for EMI
◆ Extended Burst Mode Control For Improved Efficiency and Minimum Standby Power Design
◆ Fixed 65KHZ Switching Frequency
◆ Comprehensive Protection Coverage
◇ VDD Under Voltage Lockout with Hysteresis (UVLO)
◇ Cycle-by-cycle over current threshold setting for constant output power limiting over universal input voltage range
◇ Overload Protection (OLP) with auto-recovery
◇ Over Temperature Protection (OTP) with latch shut down
◇ VDD Over voltage Protection(OVP) with latch shut down
◇ Adjustable OVP through external Zener
◆ Available in SOP8 package, RoHS compliant
Applications:
◆ Notebook Adapter
◆ LED Monitor Power
◆ Battery Charger
◆ Power Adaptor
◆ Open-frame SMPS
