LD7932R - Green Mode Off-line Power Switch

Description

The LD7932R integrates with a 700V power MOSFET and a current mode PWM controller in a DIP-7 package.

It takes less components counts or circuit space, especially ideal for those total solutions of low cost.

Features

  • more protections like OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent circuit from being damaged under abnormal conditions. Furthermore, the Frequency Swapping function is to reduce the noise level and thus helps the power circuit designers to easily deal with the EMI filter design by spending minimum amount of component cost and developing time. Features.
  • Built-in 700V Power MOSFET.
  • High-Voltage CMOS Process with Excellent ESD Protection.
  • Very Low Startup.

LD7932R 06/19/2012 Green Mode Off-line Power Switch with Brown-Out Protections REV.00 General Description The LD7932R integrates with a 700V power MOSFET and a current mode PWM controller in a DIP-7 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. It also features more protections like OLP (Over Load Protection) and OVP (Over Voltage Protection) to prevent circuit from being damaged under abnormal conditions.
