LD7912J

LD7912J 9/5/2012 Green Mode Power Switch with BNO REV：00 General Description The LD7912J is a green mode PWM controller integrated with a 700V MOSFET in a DIP-7 package. It’s capable to operate at fixed frequency of 100KHz. With multi-functions built in this device , such as high voltage startup, Burn-in/out /OLP/OVP/OTP protection, internal current mode slope compensation, and green-mode power-saving operation under light load or no load condition, this highly integrated device provides high efficiency, low external component counts, and low cost solution for compact power applications.
