The MAX1575ETE+T is a versatile charge pump LED driver designed by Analog Devices for applications requiring uniform LED intensity in main and sub-displays. It utilizes adaptive 1x/1.5x charge-pump modes and low-dropout current regulators to achieve high efficiency over a 1-cell lithium-battery input voltage range.
This device features a 1MHz fixed-frequency switching, enabling the use of tiny external components. It supports individual 5% to 100% dimming through a single-wire serial pulse interface, allowing for precise brightness control. The MAX1575ETE+T can drive up to four white LEDs in the main display and up to two in the sub-display, with a maximum drive capability of 30mA per LED. It also includes features like soft-start, output-overvoltage protection, and thermal-shutdown protection.
The MAX1575ETE+T is available in a compact 16-pin Thin QFN package measuring 4mm x 4mm with a maximum height of 0.8mm, making it suitable for space-constrained designs. Its operating temperature range is -40°C to 85°C.
Key electrical specifications include a supply voltage range of 2.7V to 5.5V and a switching frequency of 1MHz. The device offers an average efficiency of 85% and maintains 2% LED current matching.
