TEXAS INSTRUMENTS LM3429Q1MH/NOPB 发光二极管驱动器, 1输出, 升压, 降压, SEPIC, 4.5V-75V输入, 2MHz开关, 72V/1A输出, HTSSOP-14
The is a versatile high voltage N-channel MOSFET Controller for constant current LED drivers. It can be easily configured in buck, boost, buck-boost and SEPIC topologies. This flexibility, along with an input voltage rating of 75V, makes the LM3429 ideal for illuminating LEDs in a very diverse, large family of applications. Adjustable high-side current sense voltage allows for tight regulation of the LED current with the highest efficiency possible. It uses predictive off-time PRO control, which is a combination of peak current-mode control and a predictive off-timer. This method of control eases the design of loop compensation while providing inherent input voltage feed-forward compensation. It includes a high-voltage start-up regulator that operates over a wide input range of 4.5 to 75V. The internal PWM controller is designed for adjustable switching frequencies of up to 2MHz, thus enabling compact solutions.
