UC3816A
DESCRIPTION
The UTC UC3816A provides a CCM/valley switching mixed mode operation for better efficiency performance. The operation mode stays at CCM at heavy load, and switch to valley switching at light load.
The UTC UC3816A is a high performance current mode PWM controller ideally suited for low standby power. Low VCC startup current make the power reliable on startup design and a large value resistor could be used in the startup circuit to minimize the standby power. At no load condition, the IC operates in power-saving mode for lower standby power, decreasing frequency for Higher conversion efficiency at light load condition.
The UTC UC3816A contains protection with automatic recovery including OLP (over load protection), OCP (cycle-by-cycle current limiting), and UVLO (VCC over voltage clamp and under voltage lockout). It also provides the protections including OTP (over temperature protection), BNO(AC Brown Out protection) , LNO(AC Over voltage protection), OVP (VCC or DC output...
