LD7576GS LD7576PS ld7576 LCD Power Supply Chip SMD SOP-8
General Description
The LD7576X series brings high performance, and
combines highly integrated functions, protections and
EMI-improve solution. It’s an ideal solution for those
cost-sensitive systems, 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 are also equipped with
protections, such as OLP (Over Load Protection), OVP
(Over Voltage Protection) and OTP (Over Temperature
Protection), to prevent circuit damage under abnormal
conditions.
The LD7576X series is available in DIP-8 and SOP-8,
SOP-7 packages.
