5V 9A 스텝다운 전압 레귤레이터 D24V90F5
(Pololu 5V, 9A Step-Down Voltage Regulator D24V90F5)
개요
- 본 제품은 5V 9A 스텝다운(혹은 벅) 레귤레이터입니다. 출력전압에서 38V까지 입력 받아 5V로 출력을 하여 주는 제품입니다.
- 연속적으로 9A까지 출력이 가능합니다.
- 80-95%의 효율을 보이는 레귤레이터로 모터 동작과 같은 고출력 어플리케이션에 적합합니다.
특징
- Input voltage: 5 to 38 V (see below for more details on the regulator’s dropout voltage, which affects the low end of the operating range)
- Fixed 5 V output (with 4% accuracy); this can be lowered by adding an external resistor between FB and VOUT
- Typical maximum continuous output current: 9 A
- Integrated reverse-voltage protection, over-current protection, over-temperature shutoff, soft-start, and under-voltage lockout
- Typical efficiency of 80% to 95%, depending on input voltage and load; the switching frequency automatically changes at light loads to maintain high efficiencies
- 800 μA typical no-load quiescent current; can be reduced to 10 µA to 20 µA per volt on VIN by disabling the board
- “Power good” output indicates when the regulator cannot maintain its set output voltage
- Compact size: 1.6″ × 0.8″ × 0.3″ (40.6 × 20.3 × 7.6 mm)
- Four 0.086″ mounting holes for #2 or M2 screws
- Smaller holes for 0.1″ header pins and larger holes for terminal blocks offer several options for connecting to the board
