General Description
The LD7904JGP7 is a green mode PWM chip integrated with a 700V MOSFET in a DIP-6 package. It’s operating at fixed frequency of 100KHz. With multi-functions built-in this IC , such as high voltage startup, 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.
Features
Built-in 700V Power MOSFET Built-in High Voltage startup circuit Fixed Switching Frequency at 100KHz Frequency Trembling for EMI improve Internal High Voltage Startup Circuit Under Voltage Lockout (UVLO) on VCC Pin Current Mode Control with Slope Compensation Green-Mode Control for Power Saving OVP / OLP / Internal Thermal Shut Down
Applications
Switching AC/DC Adaptor LCD TV or PC Standby Power SMPS for LCD Monitor
