DESCRIPTION  
The TPS61500 is a monolithic switching regulator with integrated 3-A, 40-V power switch. It is an ideal driver for  
high brightness 1-W or 3-W LED. The device has a wide input voltage range to support application with input  
voltage from multi-cell batteries or regulated 5-V, 12-V power rails.  
The LED current is set with an external sensor resistor R3, and the feedback voltage that is regulated to 200-mV  
by current mode PWM (pulse width modulation) control loop, as shown in the typical application. The device  
supports analog and pure PWM dimming methods for LED brightness control. Connecting a capacitor to the  
DIMC pin configures the device to be used for analog dimming, and the LED current varies proportional to the  
duty cycle of an external PWM signal. Floating the DIMC pin configures the IC for pure PWM dimming with the  
average LED current being the PWM signal's duty cycle times a set LED current.  
The device features a programmable soft-start function to limit inrush current during start-up, and has built-in  
other protection features, such as pulse-by-pulse over current limit, over voltage protection and thermal  
shutdown. The TPS61500 is available in 14-pin HTSSOP package with PowerPad.
