lb11847 no.6183-12/15 sample application circuit notes on usage 1. external diodes because this ic uses upper-side transistor switching in slow decay mode an d dual-side transistor switching in fast decay mode, it requires external diodes between the out pins and ground for the regenerative current during switching off. use schottky ba rrier diodes with low vf. 2. v ref pin because the v ref pin serves for input of the set current reference voltage, precautions against noise must be taken. the input voltage range is 0 to 3.0v. 3. gnd pin the ground circuit for this ic must be designed so as to allow for high-current switching. blocks where high current flows must use low-impedance patterns and must be removed from small-signal lines. especially the ground connection for the sensing resistor re at pin e, and the ground connection for the schottky barrier diodes should be in close proximity to the ic ground. the capacitors between v cc and ground, and v bb and ground should be placed close to the v cc and v bb pins, respectively. 1.5v to 4.0v voltage setting logic input 28 27 26 25 24 23 22 21 20 19 18 17 16 15 1 2 3 4 5 6 7 8 9 10 11 12 13 14 v cc phase1 enable1 i a 1 i a 2 i a 3 i a 4 i b 4 i b 3 i b 2 i b 1 enable2 phase2 gnd md v ref 1 cr1 e1 decay1 out a out a out b out b decay2 e2 cr2 v ref 2 v bb 10
