LTC3675EUFF#TRPBF Description

Short technical summary and product information.

The LTC3675/LTC3675-1 is a digital programmable, high-efficiency, multi-output power supply and two-string LED driver IC, optimized for high-power single-cell Li-Ion/Li-Polymer battery applications. The device includes four synchronous buck converters (1A/1A/500mA/500mA), one synchronous boost DC/DC (1A), and one buck-boost DC/DC (1A), all powered from a 2.7V to 5.5V input.

 

The 40V LED driver can regulate up to 25mA of current through two strings of LEDs, each containing up to 10 LEDs. The LED driver can also be configured as a general-purpose high-voltage boost converter. DC/DC enable, output voltage, switching slew rate, and operating mode can be individually set via I2C or used in a single mode with simple I/O and power-on defaults.

 

The buck DC/DCs can be used individually or paralleled to provide higher output current with a shared inductor. LED enable, 60dB brightness control, and grayscale up/down are set via I2C. Low VIN and high chip temperature alarm levels can also be set via I2C and monitored with a maskable interrupt output for DC/DC and system faults. Button ON/OFF/reset control and a power-on reset output provide flexibility and reliable power-on sequencing.

 

The LTC3675/LTC3675-1 is available in a low-profile (0.75mm height only), thermally enhanced 44-lead 4mm x 7mm QFN package.
