Product Description

The UCC28711D is a flyback Power Supply Controller provides isolated-output Constant-Voltage (CV) and constant-current (CC) output regulation without the use of an optical coupler. It process information from the primary power switch and an auxiliary flyback winding for precise control of output voltage and current. An internal 700V start-up switch, dynamically-controlled operating states and a tailored modulation profile support ultra-low standby power without sacrificing start-up time or output transient response. The output drive interfaces to a MOSFET power switch. Discontinuous conduction mode (DCM) with valley switching reduces switching losses. Modulation of switching frequency and primary current peak amplitude (FM and AM) keeps the conversion efficiency high across the entire load and line ranges.
High-power density charger designs
Quasi-resonant valley-switching operation for highest overall efficiency
Frequency jitter to ease EMI compliance
Wide VDD range allows small bias capacitor
Clamped gate-drive output for MOSFET
Overvoltage, low-line and overcurrent protection functions
Primary-side regulation (PSR) eliminates opto-coupler
±5% Voltage and current regulation across line and load
700V Start-up switch
<10mW No-load power
Green product and no Sb/Br
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
