New launch of the new IC white light LED

Shigeru electronics recently launched white LED drive IC - APW7128. It is a white LED boost mode high power and high efficiency drive IC, input voltage range from 2.7V to 21V, the highest output voltage up to 30V, maximum inductor current up to 3.5A, efficiency up to 95%, it is suitable for large size LCD (liquid crystal display) panel backlight applications.

APW7128 has output over-voltage protection and thermal shutdown function, output overvoltage protection function can prevent LED (light emitting diode) open circuit makes the output voltage is too high and damage the IC function of thermal shutdown can avoid high power operation under high temperature damage IC IC.
