DESCRIPTION
The TPS92510 is a 60-V, 1.5-A peak current-mode step-down converter with an integrated high-side
MOSFET. It is specifically designed for driving high•
brightness LEDs with a constant current. The tight•
tolerance, 200-mV internal reference voltage reduces
power dissipation in the current-sense resistor. A dedicated pulse width modulation input pin allows
linear control of the light output.
The TPS92510 integrates a thermal foldback feature
that reduces the average output current to ensure
that the sensed LED temperature never exceeds a
specific value, improving the reliability of the overall system. An integrated frequency synchronization
feature allows a reduction of unwanted beatfrequencies
in multi-string applications and simplifies
EMI filtering. The adjustable input voltage UVLO
feature accommodates the various deep discharge
levels of multiple battery types.
The TPS92510 includes cycle-by-cycle overcurrent protection, and thermal shutdown protection. It is
available in a 10-pin MSOP PowerPAD™ package.
