Unisonic Technologies UC1108
UC1108 is a primary control unit for switch mode charger and adapter applications. The controlled variable is transferred by an auxiliary winding from the secondary to the primary side. The device uses Pulse Frequency Modulation (PFM) method to build discontinuous conduction mode (DCM) flyback power supplies.| Part No. | UC1108 |

DESCRIPTION
The UTC The UTC UC1108 operates in primary-side sensing and regulation. Opto-coupler and TL431 could be eliminated. It also eliminates the need of loop compensation circuitry while maintaining stability. The UC1108 achieves excellent regulation and high average efficiency, yet meets the requirement for no-load consumption less than 30mW. The UTC UC1108 has the built-in programmable cable voltage drop compensation function, which make it flexible to accommodate various cables with different gauges and lengths The UTC UC1108 achieves high precision CV/CC regulation and high power efficiency. It offers comprehensive protection coverage with auto-recovery features including Cycle-by-cycle current limiting, output over voltage protection, feedback loop open protection, short circuit protection, leading edge blanking, VCC under voltage lockout, etc.●
