Регуляторы напряжения - Импульсные регуляторы MAX1595ETC50+

Регулируемый DC/DC преобразователь напряжения с подкачкой заряда , 1.8 - 5.5В вход, 4.8В - 5.2В/125мА

The MAX1595ETC50+ from Maxim Integrated Products is a regulated 5V step-up/step-down charge pump in 12 pin TQFN 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.
