Регуляторы напряжения - Импульсные регуляторы MAX1595EUA50+T

Фиксированный DC/DC преобразователь напряжения с подкачкой заряда без индуктора , 1.8В - 5.5В вход

The MAX1595EUA50+T from Maxim Integrated Products is a regulated 5V step-up/step-down charge pump in 8 pin µMAX package. The unique control architecture allows the regulator to step up or step down the input voltage to maintain output regulation. The 1MHz switching frequency, combined with a unique control scheme, allows the use of a ceramic capacitor as small as 1µF for 125mA of output current. The complete regulator requires three external capacitors no inductor is needed. The MAX1595 is specifically designed to serve as a high-power, high- efficiency auxiliary supply in applications that demand a compact design. Typical applications include white LED power, flash memory supplies, miniature equipment, PCMCIA cards, 3.3V to 5V local conversion applications, backup-battery boost converters and 3V to 5V GSM SIMM cards.
