TB62701N

The TB62701N is specifically designed for LED and LED display contant current drivers.This constant current output circuits is able to set up external resistor (IOUT = 5 to 150mA).This IC is monolithic integrated circuit designed to be used together with Bi-CMOs process.

Features of the TB62701N are:(1)output current is set up at 0 to 50mA with an external resister;(2)a little change of output current ;(3)maximum clock frequency is fCLK =2.5MHz;(4)5V C-MOS compatible input;(5)package is SDIP-24(SDIP24-P-300).

The absolute maximum ratings of the TB62701N can be summarized as:(1):the characteristic is supply voltage,the symbol is VDD,the rating is 0 to 7,the unit is V;(2):the characteristic is input voltage,the symbol is VIN,the rating is -0.4 to VDD+0.4,the unit is V;(3):the characteristic is output current ,the symbol is IOUT,the rating is 50,the unit is mA;(4):the characteristic is output voltage,the symbol is VCE,the rating is -0.5 to 30,the unit is V;(5):the characteristic is clock frequency,the symbol is fCK,the rating is 2.5,the unit is MHz;(6):the characteristic is GND terminal current,the symbol is IGND,the rating is 800,the unit is mA;(7):the characteristic is power dissipation,the symbol is PD,the rating is 1.78,the unit is W;(8):the characteristic is operating temperature,the symbol is Topr,the rating is -40 to 85,the unit is ;(9):the characteristic is operating temperature,the symbol is Tstg,the rating is -55 to 150,the unit is .
