MAX1573ETE+T Description

Short technical summary and product information.

The MAX1573ETE+T is a fractional charge pump designed by Analog Devices / Maxim Integrated to drive up to four white LEDs with regulated constant current. It utilizes proprietary adaptive 1x/1.5x modes and ultra-low-dropout current regulators to maintain high efficiency across the full 1-cell Li+ battery input voltage range. The device operates with a fixed switching frequency of 1MHz, enabling the use of tiny external components and optimizing regulation for low EMI and input ripple.

 

Key electrical specifications include a 2.7V to 5.5V input voltage range, a 28mA/LED drive capability, and 0.2% LED current matching. It supports PWM dimming control and offers a low shutdown current of 0.1µA. The MAX1573ETE+T is available in a 16-TQFN (4x4) package, suitable for surface mount applications.

 

This LED driver is ideal for applications such as backlighting in cell phones, smartphones, PDAs, digital cameras, camcorders, and MP3 players. Its design eliminates the need for ballast resistors and requires no external Schottky diodes, simplifying the overall circuit design.
