LM3431AMHX/NOPB Overview
The 28-PowerTSSOP (0.173, 4.40mm Width) package conserves board space. 3 outputs are designed into LED drivers.Surface Mount is used for mounting.When it emerges as a DC DC Controller, it performs extremely well and is highly reliable.-40°C~125°C TJ is a valid operating temperature for the led driver.There are considerable benefits for Backlight.In this LED driver, the base is configured as 28.Failures may occur if the voltage supply is below 4.5V.The mount is on its way to Surface Mount.It is under the base part number LM3431 that you can find this LED driver.36V is a reasonable voltage.It achieves maximum efficiency with a minimal voltage supply of 4.5V.Electronic components can function properly when their switching frequency is set to 1MHz.When no external factors are present, there is 4mA current consumption.0.7A is the maximum output current.
