LM3557SD-2/NOPB Overview

The 8-WFDFN Exposed Pad package saves space on the board. These LED drivers have 1 outputs.The mounting method adopted is Surface Mount.Initially, it emerges as a DC DC Regulator with high efficiency and a high degree of reliability.-40°C~85°C TA is the operating temperature and it works fine.The benefits are considerable for Backlight.This system operates at 1.2MHz frequency.For its operation, 8 terminations are designed.To form its configuration, there are 8 pins.It is possible for undetermined failures to occur if the voltage supply is lower than 2.7V.The number of segments is 5.Surface Mount is mounted on it.A base part number of LM3557 is associated with this LED driver.As a maximum value, 7.5V is acceptable.The system works with a minimum supply voltage of 2.7V in order to achieve maximum efficiency.As long as the supply current is less than 800?A, this device can provide high efficiency.The load is capable of receiving 800mA current.Electronic components can function properly when their switching frequency is set to 1.25MHz.There is 22V voltage output from it.While operating the device, the circuit has 3.6V volts.
