Through the introduction of Buck technology LED driver LD7851

Tong Jia technology released a new buck LED driver LD7851, the product with constant current output, to ensure a uniform brightness of LED, and the input voltage range is wide (12V ~ 50V), the hysteresis control, without additional compensation, feedback voltage level is low, can effectively reduce the power consumption of the terminal products to meet the customer, energy saving and environmental protection product design requirements. Very suitable for driving light emitting diode (LED), the number of taking advantage of high wattage and can simultaneously drive or as many as 12 high power LED, the system is quite simple and efficient solutions, applications cover a wide range of industrial systems, indoor / outdoor, and general lighting system.

The IC can use the pulse width modulation (PWM) input signal voltage feedback control LED brightness, only 0.235V can provide the sensing function; only the components of the EN pin is connected to the external PWM control signal, it can adjust the output current, to achieve the desired LED brightness control. And the IC with current protection detection function, from the system because of the failure to work.

LD7851 provide Mini package (MSOP-10), we have now started to supply samples, welcome to sample and product specifications.
