NJU7650 Step-Down switching regulator IC with Constant Current Control ■ GENERAL DESCRIPTION The NJU7650 is a low voltage operation high-speed switching regulator control IC for step-down converter, with a constant current control. It incorporates a totem pole output, which can drive an external MOS-FET easily. It also incorporates error amplifier and current sense amplifier, which can allow the constant voltage/current control for output voltage. Therefore the NJU7650 is suitable for a LED driving, battery charger and other CCCV applications. The NJU7650 is available in a small and thin 8-lead MSOP (TVSP) package. ■ FEATURES ● PWM switching control ● Constant Current Control ● Operating Voltage 2.
