A4447SLJTR-T 제품 상세 정보
Features and Benefits
· Wide input voltage range:8 to 50V· Integrated low Rps(on) DMOS switch
·2A continuous output current
· Adjustable fixed off-time
· Highly efficient
· Adjustable output:0.8 to 24V
· Small package with exposed thermal pad
Description
The A4447 is a 2A, high efficiency general-purpose buck regulator designed for a wide variety ofapplications. The output voltage is adjustable from 0.8 to 24 V, based ona resistor divider and the 0.8 V±2% reference. External components include an external clamping diode, inductor, and filter capacitor.
The off-time is determined by an external resistor to ground.
It operates in both continuous and discontinuous modes to maintain light load regulation. An internal blanking circuit is used to filter out transients due to the reverse recovery of the external clamp diode. Typical blanking time is 200 ns.
This new device is ideal for various end products including applications with 8 to 50 V input voltage range and require up to 2 A output current, such as uninterruptible power supplies, point of sale(POS) applications, and industrial applications with 24or 36 V bus.
Applications include:
·Printer power supplies
·Office automation equipment
·POS thermal,laser,photo,and inkjet printers
·Tape drives
·Industrial applications
