ON NCP4300ADR2G

放大器电源管理表面贴装型

Overview

The NCP4300A is a monolithic integrated circuit specifically designed to control the output current and voltage levels of switch mode battery chargers and power supplies. This device contains a precision 2.6 V shunt reference and two operational amplifiers. Op−Amp 1 is designed to perform voltage control and has its non−inverting input internally connected to the reference. Op−Amp 2 is designed for current control and has both inputs uncommitted. The NCP4300A offers the power converter designer a control solution that features increased precision with a corresponding reduction in system complexity and cost. This device is available in an 8−lead surface mount package.• This is a Pb−Free Device• Low Input Offset Voltage: 0.5 mV• Input Common Mode Voltage Range Includes Ground• Low Supply Current: 210 A/Op−Amp (@VCC = 5.0 V)• Medium Unity Gain Bandwidth: 0.7 MHz• Large Output Voltage Swing: 0 V to VCC − 1.5 V• Wide Power Supply Voltage Range: 3.0 V to 35 V• Fixed Output Voltage Reference: 2.60 V• High Precision Over Temperature: 1.0%• Wide Sink Current Range: 80 A to 80 mA• Battery Charger• Switch Mode Power Supply
