This parameter models the mini- mum voltage required to be present across the current sources for them to regulate properly. This minimum voltage is proportional to the programmed LED current, so the con- stant has units of mV/mA. The typical kHR of the LM2796 is 22mV/mA. In equation form: (VPOUT - VLED kHRxILED (eq. 3) The "ILED-MAX" equation (eq. 1) is obtained from combining the Rou-r equation (eq. 2) with the kHR equation (eq. 3) and solving for ILED. Maximum LED current is highly dependent on minimum input voltage and LED forward voltage. Output current capability can be increased by raising the minimum input voltage of the application, or by selecting an LED with a lower forward voltage. Excessive power dissipation may also limit output current capability of an application. TMS320VC5472GHK 980 on stock "Write Disturb" means a phenomenon that frequent write cycles executed to pages in Flash memory may cause a data error in another page to which write operations are not performed. For example, 20,001 t0 50,000 write operations performed to pages other than page "n" may cause a l-bit error in page "n".
