CP103 Datasheet | Ceramate Technical

Description The CP103 is a monolithic IC specifically designed to regulate the output current and voltage levels of switching battery chargers and power supplies. The device contains two Op Amps and a 2.5V precision shunt voltage reference. Op Amp 1 is designed for voltage control with its non-inverting input internally connects to the output of the shunt regulator. Op Amp 2 is for current control with both inputs unmitted. The IC offers the power converter designer a control solution that features increased precision with a corresponding reduction in system plexity and cost. The CP103 is available in standard packages of DIP8 and SOP-8. Features Op Amp - Input Offset Voltage: 0.5m V - Supply Current: 75µA 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 36V Voltage Reference - Fixed Output Voltage Reference: 2.5V - Voltage Tolerance: ± 0.5%, ± 1% - Sink Current Capability from 0.05 to 80m A - Typical Output Impedance: 0.2Ω Applications - - Battery Charger Switching Power Supply SOP-8 DIP-8 Figure 1.
