LD7576/76H/76J/76K
12/5/2007
Green-Mode PWM Controller with High-Voltage
Start-Up Circuit and Adjustable OLP Delay Time
REV. 03
General Description
The LD7576X series bring high performance, combines with
highly integrated functions, protections and EMI-improve
solution. It’s an ideal solution for those cost-sensitive system,
reducing component count and overall system cost.
The LD7576X series features near-lossless high voltage
startup circuit, green-mode power-saving operation,
leading-edge blanking of the current sensing and internal
slope compensation. They also consist with more
protections of OLP (Over Load Protection), OVP (Over
Voltage Protection) and OTP (Over Temperature Protection)
to prevent the circuit damage under abnormal conditions.
The LD7576X series are available in DIP-8 and SOP-8
package.
