LM3404HVMA/NOPB General Description

Featuring a buck switching voltage regulator, the LM3404HVMA/NOPB is ideal for applications requiring high voltage conversion. Its SMD termination type and compact 8-SOIC package make it easy to integrate into various electronic designs while maintaining a small footprint. With a maximum input voltage of 75V and a maximum output voltage of 67V, this IC is capable of delivering a maximum output current of 1000A. Furthermore, it operates within a supply voltage range of 6V to 75V and is RoHS compliant, aligning with environmental regulations

Key Features

High-level of isolation between input and output
Rapidly responding to changing load conditions
Efficient power conversion with minimal losses
Safe operation in harsh environmental conditions
Fully programmable pulse width modulation
Excellent thermal management for reliability

fast shipmentworks fine. But it seems that the clock is 8Mhz not 16Mhz as serial port must be set to 19200 to get readable output although in the program it is set to 9600

It came quickly, everything is fine, thanks to the seller

Ordered the amplifier board on this trading platform from the category "collect yourself", underbanized the broken lcd tv for speakers, soldered 3,5mm "jack", found at the gas station, connected this power supply, inserted into the body of mdf, made of the trim of the shop for the production of furniture, and voila! The construction now under the music will go more fun!!!The load block of the amplifier pulls well, the tip does not give, i'm happy!I regret that i did not order two at once!
