MAX1961EEP+ Overview


Capsuled in the 20-SSOP (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. 1 outputs can be generated with the dc motor controller. PMIC packaging is solid with a Tube enclosure. There are Transistor Driver dc switching's output (s) that it can handle. dc controls with 2.35V~5.5V voltage are supplied and operated. Worked in an dc switcher with a -40°C~85°C TA rating. There is a switch at 500kHz 1MHz that can be used with this controller. Surface Mount makes it suitable for general dc dc regulator. Featured in the dcdc regulator is Current Limit, Enable, Frequency Control which allows efficient switching control. SWITCHING CONTROLLER analog IC connects the switch converters. switching converters terminal (s) are designed to be at DUAL. A variety of terminations with 20 of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. DC switcher's voltage input is 3.3V. A search for "MAX1961" will reveal other relevant dc to dc converter ics. In total, switching converter has 20 pins. Particularly, switching converter is a type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator should be 2.35V. Statistically, the DC regulator outputs 3.3V voltage. Considering the dc to dc regulator can only accept 5.5V input voltage, it is important to take note of this. A starting point for a project is to note down the dc dc regulator's usual output current, which is 20A. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 92 %. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. The max frequency of the pmic can reach 1.12MHz. DC to DC voltage regulator has a value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 4.95V to better satisfy the need.
