Overview
| Topology | Buck Converter |
| Input voltage | 3-65 V |
| Output 1 | 5 V / 0.5 A |
Description
The LM5166EVM-C50A EVM is designed to use a regulated or non-regulated high-voltage input rail (3.0 Vto 65 V) to produce a tightly regulated output voltage of 5 V at continuous current levels up to 500 mA. Inparticular, the current limit is set to one of two pre-defined levels to optimize inductor size and maximizeefficiency. The EVM's maximum output current is configured by default to 500 mA but can be changed to300 mA by suitable component selection.
Features
6V to 65V input voltage range5V target output voltageUltra-high power conversion efficiency: >90% at an output of 5 V and above 1 mA load (input voltage 12 V)COT or PFM control architectureNo-load supply current as low as 12µA
Typical applications
- Automotive and battery powered equipment
- Process control,Building automation and HVAC
- High voltage LDO replacement,General-purpose bias supplies
