FEATURES  
DESCRIPTION  
The TPS92640/41 are high voltage, synchronous  
NFET controllers for buck current regulators. Output  
current regulation is based on valley current-mode  
control with a constant on-timer. This control method  
eases the design of loop compensation. The

VIN range from 7V to 85V  
2Ω, 1Apeak MOSFET gate drivers  
Adjustable LED Current Sense voltage  
Input UVLO and output OVP  
Various dimming modes  
TPS92640/41 includes  
a
high-voltage start-up  
regulator that operates over a wide input range of 7V  
to 85V. The PWM controller is designed for high  
speed capability including an oscillator frequency  
range up to 1.0 MHz. The TPS92640/41 is optimized  
to give superior dimming performance with both  
analog and PWM dimming. Both devices include an  
error amplifier, precision reference, thermal shutdown  
and low power shutdown mode. Additionally, the  
TPS92641 provides shunt FET dimming capability.
