A current mode PWM controller designed to drive a low side external NMOS FET for wide input/output voltage range and high LED current applications. An external resistor senses the high side output current of the LED string
Quad Channel, Linear LED driver with Fault reporting (4.8V threshold), dynamic headroom control (DHC), one-fail-all-fail, and auto-recover when device enabled
The IS32LT3140A is a linear programmable current regulator consisting of a single channel 450ma led driver with heat shunt resistor and single led short detection
A PFM step-up DC-DC converter designed for driving the white LED arrays for large size LCD panel backlighting applications and can deliver stable constant output current from a few milliamps up to 2A, programmed via an external resistor
