Description
High quality BEC from Pololu. Power 12V / 2.4A with up to 50V input voltage.
Features
- Input voltage: 12.9 V to 50 V (minimum input subject to dropout voltage considerations; see the dropout voltage section for details)
- Output voltage: 12 V with 4% accuracy
- Typical maximum continuous output current: 2 A to 3.3 A (see the maximum continuous output current graph)
- Typical efficiency of 90% to 95%, depending on input voltage, output voltage, and load (see the efficiency graph)
- Switching frequency: ~500 kHz under heavy loads
- Power-save mode with ultrasonic operation that increases light load efficiency by reducing switching frequency, but keeps it above the audible range (20 kHz)
- 1 mA to 3 mA typical no-load quiescent current (see the quiescent current graph)
- Enable input with precise cutoff threshold for disconnecting the load and putting the regulator into a low-power state that draws approximately 10 µA to 20 µA per volt on VIN
- “Power good” output indicates when the regulator cannot adequately maintain the output voltage
- Output undervoltage and overvoltage protection
- Soft-start feature limits inrush current and gradually ramps output voltage
- Integrated reverse-voltage protection up to 40 V, over-current and short-circuit protection, over-temperature shutoff
- Compact size: 0.7″ × 0.8″ × 0.345″ (17.8 mm × 20.3 mm × 8.8 mm)
- Two 0.086″ mounting holes for #2 or M2 screws
