MAXIM INTEGRATED PRODUCTS MAX1686HEUA+ 芯片, 直流/直流控制器
The is a 3V to 5V regulating charge pump for SIM cards in 8 pin µMAX package. It provides power for dual voltage subscriber ID module SIM cards in portable applications such as GSM cellular phones. Designed to reside in the portable unit cellular phone handset, the 1MHz charge pump converts a 2.7V to 4.2V input to regulated 5V output. The MAX1686H has a nominal output voltage of 5V to reduce SIM card current drain. The charge pump has only 45µA quiescent supply current which reduces to 3µA when a 3V capable SIM card is being powered and the charge pump is disabled. An internal input/output shorting switch provides power for 3V SIM cards. The MAX1686H require only three external capacitors around the space-saving, thin 1mm 8-pin µMAX package. Typical applications include GSM cellular phones, PCS phones, portable POS terminals and personal communicators.
