General Description
The LD7531 is built-in with several functions, protection and
EMI-improved solution in a SOT-26/ DIP-8 package. It takes
less components counts or circuit space, especially ideal for
those total solutions of low cost.
The implemented functions include low startup current,
green-mode power-saving operation, leading-edge blanking
of the current sensing and internal slope compensation.
And the LD7531 features more protections like OLP (Over
Load Protection) and OVP (Over Voltage Protection) to
prevent the circuit damage from the abnormal conditions.
Furthermore, the frequency trembling function is to reduce
the noise level and thus helps the power circuit designers to
easily deal with the EMI filter design by using minimum
component cost and developing time.
