General Description

The AOZ1960 is a high-efficiency boost regulator with integrated 55V boost switch and 30V input protection switch.

It is designed to drive 6 parallel strings of multiple series-connected white LEDs for LCD backlight applications.

The current of each string is individually regulated by an internal current regulator.

Key Features

to protect the regulator under fault conditions. An internal 30V input protection switch protects against catastrophic failure conditions such as output short-circuits. A separate over-voltage protection (OVP) loop limits the output voltage if LED strings fail open. Cycle-by-cycle over-current protection (OCP) limits the peak inductor current. Built-in soft-start minimizes the inrush current during startup. Thermal shutdown provides another level of protection. The integrated 55V power MOSFET re.
