MBI1802
All-Ways-OnTM High-Power LED Driver
Load Supply Voltage (VLED)
MBI1802 are designed to operate with VDS ranging from 0.4V to 1.0V considering the package power dissipating
limits. VDS may be higher enough to make PD(act) > PD(max) when VLED = 5V and VDS = VLED â VF, in which VLED is the
load supply voltage. In this case, it is recommended to use the lowest possible supply voltage or to set an external
voltage reducer, VDROP.
A voltage reducer lets VDS = (VLED âVF) â VDROP.
Resistors or Zener diode can be used in the applications as shown in the following figures.
