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.
