Description
OB5282A High Voltage Green Mode PWM Controller with Brownout GENERAL .
OB5282A is a highly integrated current mode PWM control IC with high voltage startup, optimized for high performance, low standby power consumption an.
Features
* with short startup time and low standby power loss. OB5282A offers complete protection coverage including cycle-by-cycle current limiting (OCP), over load protection (OLP), over temperature protection (OTP), output and VDD over voltage protection. Excellent EMI performance is achieved with On-Bright
Applications
* The controller ‘s HV pin is used for high voltage startup, AC off detection, and X-cap Voltage discharge , this structure allows the brownout detection as well. At full loading, the IC operates in fixed frequency (65KHz) mode. When the loading goes low, it operates in Green mode with valley switchi
