MAX682ESA+

The MAX682ESA+ is a 3.3V input to regulated 5V output charge pump in 8 pin NSOIC package. This charge pump regulator generates 5V from a 2.7V to 5.5V input and specifically designed to serve as high efficiency auxiliary supplies in applications that demand a compact design. A complete 5V regulator require only one resistor and three external capacitors, no inductors are needed. High switching frequencies (externally adjustable up to 2MHz) and a unique regulation scheme allow the use of capacitors as small as 1µF per 100mA of output current. It is used in flash memory supplies, battery-powered applications, miniature equipment, PCMCIA cards, 3.3V to 5V local conversion applications, backup-battery boost converters and 3V to 5V GSM SIMM cards.

• Input voltage range is 2.7V to 5.5V
• Operating temperature range from -40°C to +85°C
• Ultra small, 1µF capacitors per 100mA of output current
• Up to 250mA output current
• Regulated ±4% output voltage
• 50KHz to 2MHz adjustable switching frequency
• 100µA quiescent current in pulse skipping mode
• 0.1µA shutdown current
