4mm Г— 7mm IC Produces Seven Regulated Outputs
and a Dual-String LED Driver
Aspiyan Gazder The LTC3675 is a space-saving single-chip power solution for multirail applications
that run from a single Li-ion cell. Its 4mm Г— 7mm QFN contains two 500mA buck
regulators, two 1A buck regulators, a 1A boost regulator, a 1A buck-boost regulator,
a boost LED driver capable of driving dual LED strings up to 25mA, and an alwayson 25mA LDO for powering a housekeeping microprocessor. All regulators can be
controlled via I2C. Figure 1 shows an eight-rail solution run from a single Li-ion battery.
SWITCHING REGULATOR FEATURES All of the voltage regulators in the LTC3675
are internally compensated monolithic
synchronous regulators. The buck regulators and the buck-boost regulator can be
enabled via enable pins or I2C, whereas
the boost regulator is enabled via I2C only.
The feedback regulation voltage of
the regulators can be programmed via
I2C from 425mV to 800mV in 25mV steps.
Each regulator offers two modes of light
load operation. The buck regulators offer
Burst Mode operation for the greatest efficiency and pulse skipping-mode for more
predictable EMI. The boost and buck-boost
regulators offer Burst Mode operation
and PWM mode. Each regulatorвЂ™s operating mode can be programmed via I2C.
The regulators also feature
I2C-programmable slew rate control …
