Pololu Adjustable 9-30V Step-Up Voltage Regulator U3V50AHV
This powerful boost regulator efficiently boosts input voltages as low as 2.9 V to a higher, adjustable output voltage between 9 V and 30 V while allowing an input current as high as 5 A.
These adjustable boost (step-up) voltage regulators generate higher output voltages from input voltages as low as 2.9 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a typical efficiency between 80% to 95%.
Features:
- Input voltage: 2.9 V to VOUT
- Output adjustable from 9 V to 30 V
- 5 A switch allows for input currents up to 5 A
- Integrated reverse-voltage protection, over-current protection, over-temperature shutoff, and under-voltage lockout
- Typical efficiency of 80% to 95%, depending on input voltage, output voltage, and load
- Compact size: 1.9″ × 0.6″ × 0.41″ (48 × 15 × 10.5 mm)
- 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
General specifications:
| Minimum operating voltage: | 2.9 V |
|---|---|
| Maximum operating voltage: | 30 V *3 |
| Maximum input current: | 5 A |
| Minimum output voltage: | 9 V |
| Maximum output voltage: | 30 V |
| Reverse voltage protection?: | Y |
| Maximum quiescent current: | 30 mA *4 |
*3The operating voltage should not exceed the set output voltage, VOUT.
*4Typical worst case (i.e. with VIN at 3 V and VOUT at 30 V). Quiescent current depends on the input and output voltages and is much lower for most of the input voltage range. The ENABLE pin can be used to reduce this to well under 1 mA.
