SP435W Dual OP AMP with Voltage Regulator DESCRIPTION The SP435W 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 precision 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. FEATURES Input offset voltage: 0.5mV Supply current: 250 uA per Op Amp at 5.0V supply voltage Unity gain bandwidth: 1MHz Output voltage swing: 0 to (VCC- 1.5) V Power supply range: 3 to 18V Fixed output voltage reference: 2.5V Voltage tolerance: 1% Sink current capability from 0.2 to 80mA 2012/01/05 V.1 APPLICATIONS Battery Power Equipment Linear Regulators Switch Power Supply Cellular Phone Digital Cameras Computer Disk Drivers Instrumentation PIN CONFIGURATION ( SOP-8 ) PART MARKING Page 1 SP435W Dual OP AMP with Voltage Regulator TYPICAL APPLCATION CIRCUIT PIN DESCRIPTION Pin Symbol Description 1 2 3 Output 1 Input 1Input 1+ VKA OP Amp Output 1 OP Amp Input 1 Voltage Power Switching Output 4 GND 5 6 7 8 Input 2+ Input 2Output 2 Vcc Ground OP Amp Input 2 Voltage OP Amp Input 2 Voltage OP Amp Output 2 Power Supply Voltage ORDERING INFORMATION Part Number Package SP435WS8RGB SOP-8 ※ SP435WS8RGB : 13” Tape Reel; Pb – Free, Halogen-Free 2012/01/05 V.1 Part Marking SP435W Page 2 SP435W Dual OP AMP with Voltage Regulator BLOCK DIAGRAM ABSOULTE MAXIMUM RATINGS (TA=25℃, unless otherwise specified.)
