MAX1957EUB+ Overview
In the 10-TFSOP, 10-MSOP (0.118, 3.00mm Width) package, the switching controller meets most application requirements. For 1 outputs, the dc motor controller is appropriate. There is a Tube solid enclosure around the pmic. Transistor Driver dc switching's outputs (s) are supported. The supply and operating voltage of the dc control are 3V~5.5V. Suitable for a -40°C~85°C TA dc switcher. The switching controller is capable of switching at the 300kHz position. The Surface Mount makes it ideal for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Current Limit. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Thare switching converters has a terminal (s) at DUAL . An array of 10 terminations of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's input voltageis 5V volts. You can find other relevant dc to dc converter ics by searching "MAX1957". There are only 10 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. An input voltage of 3V is the minimum required for the dc dc voltage regulator. DC regulator outputs 4.73V voltage based on test statistics. A maximum voltage of 5.5V is accepted by the dc to dc regulator as an input voltage. normally, the dc dc regulator's output current is 3A, which you should keep in mind when starting a project. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 89 %. This Surface Mount makes DC switcher suitable for most prototypes and applications. This dc regulatorhas a max frequency of 360kHz. This value is ALSO OPERATES IN CURRENT MODE so that DC to DC voltage regulator better serves the purpose.
