PFET降压控制器的高功率LED驱动器 PFET Buck Controller for High Power LED Drivers
The LM3409, LM3409-Q1, LM3409HV, and LM3409HV-Q1 are P-channel MOSFET PFET controllers for step-down buck current regulators. They offer wide input voltage range, high-side differential current sense with low adjustable threshold voltage and fast output enable/disable function and a thermally enhanced 10-pin, HVSSOP package. These features combine to make the LM3409 family of devices ideal for use as constant current sources for driving LEDs where forward currents up to 5 A are easily achievable.
The LM3409 devices use constant off-time COFT control to regulate an accurate constant current without the need for external control loop compensation. Analog and PWM dimming are easy to implement and result in a highly linear dimming range with excellent achievable contrast ratios. Programmable UVLO, low-power shutdown, and thermal shutdown complete the feature set.
