Description
The XL7035E1 is a high-efficiency, step-down DC-DC converter IC designed for applications requiring stable, adjustable output voltages. Key features include:
- Input Voltage Range: 5V to 40V
- Output Voltage: Adjustable from 1.25V to 37V
- Output Current: Up to 2A (with proper heat dissipation)
- High Efficiency: Up to 95% (PWM mode)
- Switching Frequency: 180kHz (fixed)
- Protections: Overcurrent, thermal shutdown, and short-circuit protection
It operates in PWM mode for high efficiency under heavy loads and automatically switches to PFM mode at light loads to reduce power loss. Common applications include power supplies for industrial equipment, automotive systems, and consumer electronics.
The XL7035E1 is available in a TO-252-5L package, making it suitable for compact designs. External components like inductors, capacitors, and resistors are required for voltage adjustment and stability.
For detailed specifications, refer to the datasheet from the manufacturer.
