LM3409

用于高功率 LED 驅(qū)動(dòng)器的 42V PFET 降壓控制器; ? LM3409-Q1 and LM3409HV-Q1 are Automotive Grade Products: AEC-Q100 Grade 1 Qualified\n? 2-?, 1-A Peak MOSFET Gate Drive\n? VIN Range: 6 V to 42 V (LM3409, LM3409-Q1)\n? VIN Range: 6 V to 75 V (LM3409HV, LM3409HV-Q1)\n? Differential, High-Side Current Sense\n? Cycle-by-Cycle Current Limit\n? No Control Loop Compensation Required\n? 10,000:1 PWM Dimming Range\n? 250:1 Analog Dimming Range\n? Supports All-Ceramic Output Capacitors and Capacitor-less Outputs \n? Low-Power Shutdown and Thermal Shutdown\n? Thermally Enhanced 10-Pin, HVSSOP Package;

The LM3409, LM3409-Q1, LM3409HV, and LM3409HV-Q1 are P-channel MOSFET (PFET)controllersfor step-down (buck) current regulators. They offer wide inputvoltage range, high-sidedifferential current sense with low adjustablethreshold voltage and fast output enable/disablefunction and a thermallyenhanced 10-pin, HVSSOP package. These features combine to make the LM3409 family of devices ideal for use as constant current sources for driving LEDswhere forward currentsup to 5 A are easily achievable. The LM3409 devices use constant off-time (COFT) control to regulate anaccurate constantcurrent without the need for external control loopcompensation. Analog and PWM dimming are easy toimplement and result in ahighly linear dimming range with excellent achievable contrast ratios. Programmable UVLO, low-power shutdown, and thermal shutdown complete thefeature set.For all available packages, see the orderableaddendum at the end of the data sheet.
