HM4310 Dual op AMP and voltage reference
■The HM4310 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 connected 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.
