LN5071 Overview
The LN5071 series of internal integration of two highly precise, low noise, positive voltage LDO regulators manufactured using CMOS processes. The device used in portable electronic products drive main or vice screen backlight modules and the provision of low-voltage system voltage source. LN5071 can drive four LEDs, each LED currents up to 20mA, through the PWM signal can adjust average brightness, the constant...
