LD7576A
1 1/29/2009
Green-Mode PWM Controller with High-Voltage
Start-Up Circuit and Adjustable OLP Delay Time
REV. 00b
General Description
The LD7576A brings hi gh performance, and com bines
highly inte grated functions, protections an d EMI-improve
solution. It’s an id eal so lution for those cost-sensitive
systems, redu cing comp onent count and overa ll s ystem
cost.
The LD7576A features near-lossless high v oltage startup
circuit, green-mode power-saving operation, leading-edge
blanking of the curre nt sensi ng an d i nternal slop e
compensation. They are also equipped with protections,
such as OLP (Over Load Pro tection), OVP (Over Voltage
Protection) and OT P (Over T emperature Protection), to
prevent circuit damage under abnormal conditions.
