2ch Switching Regulator IC
The NJU7680 is a high-speed low voltage operation switching regulator control IC. It features a totem pole driver that can directly drive an external MOS-FET.Each channel has an on/off switch. Therefore, the power sequence can be activated externally.Internal soft-start function, dead time control and timer latch function are included, and those functions can be easily controlled by external component.
Consumer Input Voltage Range 2.3 V to 7 V (8 V) Operating Temperature Range -40°C to 85°C Supply Current Typ. 1000 µA Standby Current 3 (max.) µA Output Voltage Range 1 V to - V Output Voltage Accuracy ± 1.5 % Oscillator Frequency 300kHz to 1MHz Control PWM switching control Function Soft-Start Function Internal (4ms typ. or adjustable)
