LD7539E Datasheet (Leadtrend Technology) - Green-Mode PWM Controller

LD7539E, Green-Mode PWM Controller

The LD7539E is built-in with several functions, protection and EMI-improved solution in a tiny 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,

LD7539E Features

* more protections like BNO (Brownout), OTP (Over Temperature Protection), OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent circuit damage occurred under abnormal conditions. Furthermore, the Frequency Swapping function is to reduce the noise level and thus helps the power circu
