PMP7761, 24V input to 14V@6A, Non Sync Buck LED Driver Reference Design
Progetto di riferimento di: Texas Instruments
It is a High current Non Synchronous buck DC-DC LED driver. The LM3409 uses 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 shut-down, and thermal shut-down complete the feature set
