Description
The MP1482DN-LF-Z is a synchronous buck converter from Monolithic Power Systems (MPS). It features a 4.5V–28V input range, delivers up to 2A output current, and operates at a 340kHz fixed switching frequency.
Key characteristics:
- High efficiency (up to 95%) with integrated power MOSFETs.
- Adjustable output voltage (0.8V–24V).
- Low standby current (50μA) in shutdown mode.
- Protections: Over-current (OCP), thermal shutdown (TSD), and under-voltage lockout (UVLO).
Applications include industrial, automotive, and consumer electronics where compact, efficient power conversion is needed. The DFN-8 (3x3mm) package makes it suitable for space-constrained designs.
For detailed specs, refer to the datasheet.
