This small synchronous switching step-down regulator accepts an input voltage of up to 36 V and efficiently reduces it to 6 V. The board measures only 0.7″ × 0.7″, but delivers a typical continuous output current of up to 2.5 A and is reverse polarity protected. Typical efficiencies of 85% to 95% make this controller well suited for supplying medium loads such as sensors or small motors. An optional shutdown pin enables a low power state with a current consumption of approximately 30 to 350 mA, depending on the input voltage. A power good output indicates when the controller cannot maintain the output voltage sufficiently.
These controllers have a typical quiescent current consumption (no-load) of about 1 mA, and an enable pin can be used to put the boards in a low-power state that reduces the quiescent current to about 5 µA to 10 µA per volt on VIN.
>The modules have integrated reverse polarity protection, short-circuit protection, thermal shutdown to prevent overheating, and a soft start function to reduce inrush current.
>Input voltage:
- 4 V to 36 V for versions with 3.3 V outputs />[output voltage + dropout voltage] to 36 V
- for output voltages from 5 V and higher
- Fixed output 3.3 V, 5 V, 6 V, 7.5 V, 9 V or 12 V (depending on controller version) with 4% accuracy
- Typical maximum continuous output current: >2 A
- Typical efficiency from 85% to 95%, depending on input voltage, output voltage and load
- Switching frequency: ~400 kHz
- Integrated reverse polarity protection, overcurrent protection, overtemperature shutdown and soft start integrated
- 1 mA typical no-load quiescent current; this can be set to approx. 5 µA to 10 µA per Volt can be reduced to VIN.
- The "Power good" output indicates when the controller cannot maintain the output voltage sufficiently.
- Compact size: 0.7″ × 0.7″ × 0.7″ × 0.7″ × 0.31″ (17.8 mm × 17.8 mm × 8 mm)
- Two 0.086″ mounting holes for #2 or M2
