DC-DC преобразователи интегральные MAX606ESA+

Импульсный повышающий DC-DC стабилизатор , регулируемый, 3В-5.5В вход, 1МГц, 3В-12.5В/180мА выход

The MAX606ESA+ from Maxim Integrated Products is a low profile, 5V/12V or adjustable, step-up DC-DC converter for flash memory/PCMCIA cards in 8 pin NSOIC package. This CMOS, step-up DC-DC converter employs a current-limited pulse frequency control scheme. This control scheme regulates a boost topology to convert input voltages between 3V and 5.5V into either a pin-programmable 5V/12V output or an adjustable output between VIN and 12.5V. It optimizes performance over all input and output voltages, it gives output accuracy to ±4%. The MAX606 switches at up to 1MHz and fits type 1 (thinnest standard) flash memory and PCMCIA cards. It uses a thin, 1.19mm high, 5µH inductor and small, 0.68µF output capacitors. The entire circuit fits in 0.25in² and is less than 1.35mm high. It is used in PCMCIA cards, memory cards, single PCMCIA slot programming, digital cameras, flash memory programming and hand held equipment.
