• Manufacturer Part Number: tb62726afg
• Description: 16-bit Constant-current Led Driver With Operating Voltage Of 3.3-v And 5-v
• Manufacturer: TOSHIBA Semiconductor CORPORATION

TB62726ANG/AFG
Application Circuit (example 2): When the condition of VLED is VLED > 17 V
The unnecessary voltage is one effective technique as to making the voltage descend with the zenor diode.
Example)
TD62M8600F: 8-bit multi-chip PNP transistor array, which
is not used in static lighting system.
