General Description
Features
The IS31LT3515 is a current mode PWM controller designed to drive an external MOSFET for high current LED applications.
With a current sense amplifier threshold of 250mV, the LED current is programmable with one external current sense resistor.
The IS31LT3515 is ideal for buck, boost or buck-boost operation.
With 250kHz operating frequency (typical, and this frequency can be set up by external resistor), the external inductor and capacitors can be small while maintaining high efficiency.
Dimming can be either analog or PWM digital.
