SLVSDD9 – MARCH 2017 TPS92692, TPS92692-Q1 High Accuracy LED Controller With
Spread Spectrum Frequency Modulation
1 Features 3 Description The TPS92692 and TPS92692-Q1 are high accuracy
peak current mode based controllers designed to
support step-up/down LED driver topologies. The
device incorporates a rail-to-rail current amplifier to
measure LED current and spread spectrum frequency
modulation technique for improved EMI performance. 1 Wide Input Voltage: 4.5 V to 65 V
Better than В± 4% LED Current Accuracy over
–40°C to 150°C Junction Temperature Range
Spread Spectrum Frequency Modulation for
Improved EMI
