5-V to 60-V Input Voltage Range • Integrated 200-mΩ High-Side MOSFET • 200 mV Internal Voltage Reference • ±3% LED Current Accuracy • 100 kHz to 2.
5 MHz Switching Frequency Range • Dedicated PWM Dimming Input • LED Thermal Foldback • Adjustable UVLO • Overcurrent Protection • Over-Temperature Protection • MSOP-10 (DGQ) PowerPAD™ Package APPLICATIONS • Street Lighting • Emergency Lighting • General Illumination • Industrial and Commercial Lighting • MR16 LED Bulbs 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 highbrightness LEDs with a constant current.
The tighttolerance, 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.
