Aimed at architectural and general lighting applications, Texas Instruments'
TPS92691 multi-topology LED driver is now available from Mouser stock. The
versatile LED controller can support a range of step-up or step-down driver
topologies.
The device implements a fixed-frequency peak current mode control technique
with programmable switching frequency, slope compensation, and soft-start
timing. It incorporates a high voltage (65V) rail-to-rail current sense
amplifier that can directly measure LED current using either a high-side or
a low-side series sense resistor. The amplifier is designed to achieve low
input offset voltage and attain better than ±3% LED current accuracy. This
is done over a junction temperature range of 25C to 140C and output
common-mode voltage range of 0 to 60V.
