특징
- Input voltage: 2.9 V to VOUT
- Output voltage: 4.5 V to 20 V (precision-adjustable using built-in 12-turn potentiometer)
- True shutdown option turns off power to the load
- Typical efficiency of 80% to 95%, depending on input voltage, output voltage, and load (see the Typical efficiencies and output currents section below for performance graphs)
- 10 A switch allows for:
- Instantaneous input currents up to 10 A
- Input currents up to 8 A for several seconds
- Input currents around 6 A to 7 A for prolonged durations, depending on input voltage and output voltage
- low quiescent current for most combinations of input and output voltages (see the quiescent current graph below for more details)
- Integrated protections:
- Reverse voltage protection
- Short-circuit protection with hiccup recovery
- Over-temperature shutoff
- Under-voltage lockout (typical thresholds are 2.4 V falling, 2.8 V rising)
- Cycle-by-cycle input current limiting to 10 A
- Compact size: 1.6″ × 0.6″ × 0.22″ (40.6 × 15.2 × 5.5 mm)
- Weight: 3.9 g
- Two 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
