Product details

Description

The AOZ1934/5 is an ideal power solution for white LED backlighting for medium to small size LCD panels.

It is a highly integrated step up DC-DC converter with input voltage range from 2.7V to 25V, accommodating 1-, 2-, 3-, or 4-cell lithium ion batteries or 3.3V, 5V, 12V or 20V regulated supplies.

Features

are built into the AOZ1934/5, including cycle-by-cycle input current limit protection, output over-voltage protection, LED fault (open or short) protection and thermal shutdown protection. The leakage current in shutdown mode is 0.1µA. The AOZ1934/5 is available in a 16-lead 3 x 3 x 0.75mm thin QFN package. Features z Wide input range: 2.7V to 25V z Drive up to 30 LEDs.
AOZ1934 up to 20 LEDs (10s2p).
AOZ1935 up to 30 LEDs (10s3p) z Up to 92% efficiency z High frequency step-up.
