Boost Converter with fixed 5.1V Output

We are happy to now produce this high efficiency boost converter. The circuit has excellent efficiency and great thermal performance. Some stats: 5.1V fixed output voltage. Up to 97% efficiency. Up to 3.5A output for 3.3V to 5.1V conversion. The circuit has an enable pin which is active by default. You can interface with a microcontroller or external switch by simply cutting the trace on the bottom of the PCB (as pictured). The circuit also has +5V and ground pins broken out. This circuit does not seem to get very hot during testing at 1-1.5amp loads.
