HV9910 is a highly efficient, stable and reliable high-brightness LED lights-driven control IC, compared with built-in high-precision, off-time control circuit, such as constant current drive circuit, particularly for high-power, a number of high-brightness LED lights constant string Flow-driven.
9910 fixed off-time control, its frequency can be as high as 2.5 MHz, will enable external inductors and filtering, high-volume reduction, increased efficiency. off-time minimum time, through external resistors and inductors set, the frequency can be changed according to user requirements. EN-plus in the PWM signal, can adjust the brightness of LED lights.
Through the adjustment of external resistance, to control high-brightness LED lights of the current drive to achieve the desired brightness LED lights constant brightness, high-brightness LED lights from the current one amp a few milliamperes to change.

Characteristics:
Programmable LED drive current, programming range of a few milliamperes to one amp
High efficiency: 90%
Wide input voltage range: 2.5 V ~ 400V
High frequency:> 2.5 MHz
Adjustable frequency: 500 KHz ~ 2.5MHz
LED lights-driven features: LED lights from a string to hundreds of high-brightness LED lights
PWM brightness can be adjusted: EN-side, adjusting brightness LED lights
