LM5576 high power wide voltage DCDC, input up to 75V 3A

Overview

The LM5576-Q1 is an automotive grade product and qualified for AEC-Q1001 grade (operating junction temperature range -40°C to +125°C) and AEC-Q100 Grade 0 (operating junction temperature range -40°C to +125°C). +150°C) integrated 75V 170mΩ N-channel metal oxide semiconductor field effect crystal

Ultra-wide input voltage range: 6V to 75V

Adjustable output voltage as low as 1.225V

Can provide 3A continuous output current

The efficiency of the power amplifier is quite high, but it will also generate heat when working at high power, so certain heat dissipation measures need to be taken. Pay attention to component selection

The attachments include manuals and official evaluation board product pictures. It is recommended that the solder mask on the back be made larger.

There is actual test data in the attachment. It can be seen that the efficiency is quite good. The external load is 31Ω.
