9.5 Boost Regulator
The boost regulator boosts the input voltage to the regulated output voltage that drives the LED anodes. The MSL3086/88 boost
regulators use external MOSFET switches and current sense resistors, allowing a wide variety of input/output voltage combinations and
load currents. The boost regulator switching frequency is 625kHz. Switching frequencies of 350kHz, 500kHz, 750kHz, 875kHz and 1Mhz
are also available; contact the factory for information.
