MAX638 CMOS DC-DC boost converter is a switched regulator, it has a interior MOS FET that has a peak of 375mA, this FET can constitute a 5-W DC-DC converter. Its voltage output is adjustable and input volage range is 2.0~16.5V. For this converter, typical efficiency is 85%, voltage variation ±1.5%, typical static current 70µA, oscillation frequency 10kHz. Maximum ouput voltage of LX and LBO terminal is 18V, peak of output current of LX is 375mA, LBO 50mA. If room temperature drops to below 50℃, power of DIP platic encapsulation will be 468mW, micro platic encapsulation will be 441mA, and ceramic encapsulation 833mW. Working temperature range of MAX630C is 0~+70℃, MAX630E -40~+85℃, MAX630M -55~+125℃. This converter has an interior circuit for input voltage-detection.
