12-75V Input to 10V Output DC-DC Buck Converter
This is a versatile synchronous Buck DC/DC converter built using the LM5007 chip. It operates with an input voltage range 12V to 75VDC, and provides 10V/250mA output. The regulator can provide load current up to 400mA, but it is advisable to draw only 250mA due to the small thermal area (small PCB). The default output of the converter is set to 10Vdc. The output is adjustable by changing the feedback resistor values R1 and R4. You may refer to the datasheet of the LM5007 chip for more info.
Features
- Operating Input Voltage Range of 12 V to 75 V
- Output 10V @ 250mA (Output Up to 400mA with forced air)
- Adjustable Output Voltage
- High-Efficiency Operation
- Adaptive Constant On-Time Control Architecture
- Ultra-Fast Transient Response
- No Control Loop Compensation Required
- Nearly Constant Switching Frequency
- PWM On-Time Varies Inversely with Input Voltage
- Low Input Quiescent Current
- Inherent Protection Features for Robust Design
- Intelligent Current Limit Protection
- VCC and Gate Drive UVLO Protection
- Thermal Shutdown Protection with Hysteresis
- PCB Dimensions 20 x 14.29mm
