The 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%. It switches at up to 500KHz, fitting Type 2 and 3 cards as well as hand-held devices where height requirements are not as critical. Other features include 1µA logic controlled shutdown and user controlled soft-start to minimize inrush currents. It is used in single PCMCIA slot programming, digital cameras and flash memory programming.
