ts 103 /a dual operational amplifiers and voltage reference 1 / 6 version: b 07 sop - 8 general description the TS103 is a monolithic ic specifically designed to control the output current and voltage levels of switch mode battery chargers and power supplies. the device contains two operational amplifiers and a prec ision shunt regulator. op amp 1 is designed for voltage control, whose non - inverting input internally connects to the output of the shunt regulator. op amp 2 is for current control with both inputs uncommitted. the ic offers the power converter designer a control solution that features increased precision with a corresponding reduction in system complexity and cost. absolute maximum rating parameter symbol value unit power supply voltage (v cc to gnd) v cc 20 v op amp 1 and 2 input voltage range (pins 2,5,6) v in - 0.3 to v cc +0.3 v op amp 2 input differential voltage (pins 5,6) v id 20 v voltage reference cathode current (pin 3) i k 100 ma power dissipation p d 500 mw storage temperature range t stg - 65 to 150 c esd protection voltage (machine model) -- 200 v note 1: stresses greater than those listed under "absolute maximum ratings " may cause permanent damage to the device. these are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated u nder "recommended operating conditions" is not implied. exposure to "absolute maximum ratings " for extended periods may affect device reliability. features input offset voltage: 0.5mv supply current: 250ua per op amp @ 5v unity gain bandwidth: 1mhz output voltage swing: 0~(vcc 1.5) v power supply voltage: 3~18v fixed output voltage reference: 2.5v 1% sink current capability from 0.2~80ma package types: sop - 8 ordering information part no. package packing TS103cs rl sop - 8 2.5k pcs / 13 reel TS103 a cs rl sop - 8 2.5k pcs / 13 reel block diagram pin assignment : 1. outp ut a 8. vcc 2. input a ( - ) 7. output b 3. input a (+) / vka 6. input b ( - ) 4. gnd 5. input b (+)
