LM1770SMF/NOPB Product Details
LM1770SMF/NOPB Overview
This switching controller fits most application requirements since it is packaged in a SC-74A, SOT-753 package. 1 outputs can be generated with the dc motor controller. PMIC is packaged in a solid enclosure of Tape & Reel (TR). Transistor Driver dc switching's outputs (s) are supported. 2.8V~5.5V is the operating voltage and supply voltage of the dc control. Suitable for a -40°C~125°C TJ dc switcher. There is a switch at 100kHz~1MHz that can be used with this controller. dc dc regulator is made easier with Surface Mount. An analog IC SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . A variety of terminations with 5 of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis set to 3.3V. You can find other relevant dc to dc converter ics by searching "LM1770". There are only 5 pins on switching converter. dc dc voltage regulators should have a minimum input voltage of 2.8V. DC regulator outputs 4.5V voltage according to the test statistics. normally, the dc dc regulator's output current is 4A, which you should keep in mind when starting a project. voltage regulator dc to dcs with a 95 % duty cycle are designed to be reliable when powered on and powered off. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. DC regulator's maximum frequency is 1MHz. The value of DC to DC voltage regulator is set to ALSO HAS ADJUSTABLE OUTPUT VOLTAGE AS LOW AS 0.8V in order to better satisfy the requirement. In order to run the voltage regulator dc to dc safely and reliably, users are advised to apply 5.5V. When the dc switching is dormant, it uses 400μA.
